Simultaneous sound playback. How to set up speakers on a computer - simple ways. Output sound to different devices. What does "default device" mean?

At the very beginning, I want to explain how the sound interface on a computer works so that you understand what we will talk about next.

The computer sees any device that is capable of producing sound, separately from others. If a typical computer has only one sound card, either built-in or separate, then in some cases there may be many more of these devices.

In order to allow a person to control these devices, as well as to automate sound playback in general, Windows computers have a special item in the audio output settings called “default device”.

How to get to the control panel for audio devices in Windows

Find the clock in the lower right corner of the screen, to the left of it there will be a “Speaker” icon, right-click on it.

In the pop-up menu, select “Sounds” and left-click on it.

You are now in the Windows audio device management menu. For the purposes of this article, we are only interested in the “Playback” tab.

What does "default device" mean?

This menu item shows us which device is in this moment is responsible for outputting sound or recording sound.

For example, if your computer has many sound-reproducing devices installed, then this setting will show which device is currently playing sound.

Default audio output device in general

Let's imagine that you have only one sound-reproducing device in your computer - a sound card built into the motherboard.

There will be only one in the list and, of course, it will be the default device and you will not experience any problems.

However, if you connect USB headphones or a USB speaker to this computer, then 2 devices will appear in the list.

If you connect a monitor with built-in speakers to your computer, there will already be 3 devices and this list can go on for a very long time.

Therefore, it is important to understand how to adjust and configure Windows so that you can listen to sound through the device you need.

Let's say you have one sound card and you connected a monitor with speakers, and you already have good speakers, which are connected to the sound card.

Of course, the sound quality of individual speakers will be better than those built into the monitor, so in order for sound to be output from individual speakers, we need to select a sound card as the default playback device.

After we have selected the sound card as the default device, all sound from the computer will be output through it.

Selecting an audio device in the application

Let's return to our situation when we have 2 sound reproduction devices: speakers built into the monitor and a separate sound card.

In the settings of all such applications there is an item that allows you to select the sound playback and recording devices that will be used when this application is active, regardless of which device was selected by default in Windows.


Let's go to the audio settings of the Discord program. We see that we can select separate devices for recording audio and outputting it. What does this give us?

We can choose the same audio output device that is used for everything else, or we can choose a separate one. This way we can split multiple audio streams for output to different devices.

For example, you have good external speakers that you use to sound the game, and there are speakers built into the monitor that you do not use at all. By adjusting the audio output devices inside Discord, you can make sure that the voice of your interlocutors is output through the speakers in the monitor, and the game audio is output through good external speakers.

To do this you need to Windows device By default, select external speakers, the game will see these settings and use it for itself. And in Discord we will select the speakers in the monitor as the audio output device. Now all the voices of the interlocutors will be voiced by the monitor, and the game will be played by good speakers.

As you understand, this is just an example, you can choose any sound devices in the way that is convenient or appropriate for you.

In the same way, you can choose different sound recording devices if you have several microphones. One microphone will be used for one application, and the second for another, or vice versa.

USB headphone connection vs regular connection

Is there a difference between a device connected via USB and using a standard TRS jack?

Yes, there is a difference. It lies in the fact that any additional USB device that is capable of playing sound is considered separate from the others by Windows and can be flexibly managed. While your sound card is seen by Windows as one device, and if you connect speakers and headphones to it at the same time, Windows will still see them as one sound-reproducing device.

But what if you want to switch between speakers and headphones that are connected to the same device?

There is a solution, but I will only describe the general algorithm, because... Each sound-reproducing device may differ significantly from the other in its proprietary application interface or settings.

Make sure that you have installed on your computer latest version drivers and proprietary software for your audio device. This is a must.

Is it possible to set up automatic switching from speakers to headphones and vice versa?

Let's consider a situation where you have one sound card to which you simultaneously connect headphones and speakers.

You connected the speakers to the green output on the back of the computer, and the headphones to the audio jack on the front of the computer.

If the front panel is connected to the sound card correctly, the sound card software will automatically switch between speaker and headphone output.

Windows will always be sure that the sound is output through the sound card, and will give it the entire audio stream for processing and output. The sound card will independently determine whether headphones are connected or not and output sound to them.

How to switch audio output to headphones if the front panel does not work

Some sound cards can change the purpose of the jacks on the rear panel of the computer depending on the situation. For example, in some cases the line input (usually indicated in blue) can be used as a separate headphone input.

Do not connect headphones to the line input unless you have verified that it is now functioning as a headphone input. Otherwise, you risk damaging your headphones.

You can find out whether your sound card supports this operating mode either in the sound card settings or by reading the instructions.

If the sound card can use the line input as a headphone output, then your problem is solved and when you connect headphones, the sound will automatically be routed to them.

If the sound card does not support this mode of operation, you will have to manually disconnect the speaker jack, then connect headphones to the audio jack (usually indicated in green).

At the same time, in the settings of the sound card, before connecting the headphones, it is necessary to reduce the volume level to minimum and switch the operating mode of the green output to the “headphones” mode, if possible.

If the sound card continues to operate in "speakers" mode and you connect headphones, it may damage the headphones due to too much current that the sound card will generate to drive the speakers.

Switching audio output from speakers to headphones using proprietary sound card software

In some cases, the sound card will have either a separate output for connecting headphones, or a separate mode for outputting sound to headphones through a common audio jack, which must be activated through proprietary software.

For example, I use my sound card Creative Sound Blaster ZxR.

In my case, I need to manually switch the operating mode of the sound card from speakers to headphones, but I don’t need to physically switch the jacks.

This is not very convenient, but is completely justified, because... This sound card has two physical jacks for connecting headphones and speakers, which have different signal amplification schemes and it is impossible to switch them automatically due to the design.

This is not very convenient, but is fully compensated by the excellent sound quality.

If I understand well, there are two questions here.

Is it possible to play sound on two or more audio output devices at the same time and how to achieve this?

Is it possible to loop the data through an audio input (recording) device so that it plays on the appropriate monitor, for example sent via a Skype audio stream to your partner in your respective case.

Reply to 1: This device is absolutely possible, but all of your system's independent audio outputs can play sounds simultaneously. For example, some professional audio interfaces (for music production) have 8, 16, 64 independent outputs, all of which can be played simultaneously. This means that each output device maintains its own buffer, which it consumes independently (apart from the parallelism in the final shared memory for supplying the buffer).

Most audio frameworks/systems provide functions that allow you to get a "device handle" in which you will need to pass a callback to feed the sample buffer (eg Open AL). This will be called independently and asynchronously by the framework/system (ultimately the audio device drivers). Since this all works asynchronously, you don't necessarily need multithreading. All you have to do basically is support two (or more) audio output devices, each using a separate callback to feed two (or more) separate devices.

Note You can also play multiple sounds on one device. Most devices/systems allow this kind of "resource sharing". In fact, this is one of the purposes for which sound cards are actually designed. Mix all sounds created various programs(and therefore take that heavy load off the CPU). When you use one (physical) device to play multiple sounds, the concept is the same as for multiple devices. For each sound you get a logical device handle. Only that these descriptors refer to multiple “channels” of a single physical device.

What should you use?

Open AL seems a bit like using heavy artillery for this simple task I would say (since you don't want What Lots of portability, and probably doesn't plan to implement its own codec and effects ;))

I would recommend you to use Qt here. It's very portable (Win/Mac/Linux) and it has a very handy class that will do the job for you: http://qt-project.org/doc/qt-5.0/qtmultimedia/qaudiooutput.html

Check out the example in the documentation to see how to play a WAV file, with a few lines of code. To play multiple WAV files at the same time, you just need to open multiple QAudioOutputs (basically, output the code from the example into a function and call it as often as you want). Please note that you need to close/stop QAudioOutput for the audio to stop playing.

Reply to 2: What you want to do is called loopback. Only a very limited number of sound cards, e.g. audio devices, provide a so-called loop input device, which allows recording of what is currently output by the main output combination of the sound card, e.g. However, even if such a device is provided, it will not allow you to push anything into the microphone input device. The microphone input device only accepts data from the microphone D/A converter. It's deep in H/W, you can't mix anything at your level.

It will be very hard (IMHO almost impossible) to have Skype send your audio standard setting to your conversation partner. The only thing I can think of is to have an audio device with loopback capabilities (or just a physical cable connection to a possible line of monitors to any recording line) and then have Skype configured to use that device with feedback as input, However, Skype will not pick up from the microphone anymore, which means you won't have a conversation ;)

Note: When we say "simultaneous" playback here, we are talking about synchronizing the playback of two sounds as perceived in real time (in the range of 10-20 ms). We're not looking at actual sample-level synchronization and the associated jitter and phase shift issues that arise when transmitting audio to two physical devices with two independent (free running) clocks. Thus, when an application requires phase signal generation on independent devices, clock recovery mechanisms are needed, which can be provided by drivers or the OS.

Note: Virtual audio device software such as Virtual Audio Cable will provide virtual devices to provide loopback functionality in Windows. Environments like Jack Audio can be the same in a UX environment.

Connecting audio from your computer to your TV expands its capabilities, improving the sound quality of music or movies. There are several ways to do this, they all have their pros and cons, so it is necessary to give preference to one method or another, taking into account the characteristics of the equipment and its capabilities. Before you connect audio from your computer to your TV, you need to make sure that your devices have one of these connectors.

Main types of connectors

Almost all modern equipment is equipped with one of these types of connectors. They are designed for connecting external storage media, video and DVD players, as well as other digital equipment, which includes a computer.

The most used types of connectors are:

• HDMI;
• Wi-Fi;
• RJ45;
• RCA cable.

Ways to connect sound from a computer

Via HDMI connector

Audio output through this connector is the most popular, since problems and malfunctions are less likely to occur with it, and the sound quality remains good. This cord may be included with some digital devices, and will be sold separately.

There is no need to purchase an overly expensive cord, since regardless of the price, the same materials are used in its manufacture, which do not change the sound quality.

To connect your TV to your computer, you first need to disconnect both devices from the power supply and then connect them using a cord. This connection method does not require any additional settings, just specify the HDMI output on the TV as the audio source.

Possible problems when connecting devices

• If the sound does not play, then you need to use your computer to set the TV as the sound source. To do this, right-click on the sound icon in the lower left part of the taskbar and select “Playback devices” from the pop-up menu. From the list you need to select your device, right-click on it and check the box next to the “Set as default” menu item.

When setting up, the devices must be connected to each other. If the computer does not see the TV when the HDMI cable is turned on, then you need to restart it and repeat the setup procedure again.

• You also need to make sure that the video card supports audio playback via the HDMI output. Often all modern devices are equipped with this function. However, some of them include a special jumper that helps create a connector for the SPDIF out connection" on system board with the “SPDIF in” connector on the video card.
• You can solve the problem if you reinstall or update the drivers for the video card.

How to connect sound from a computer to a TV via a Dvi cable?

The second most popular method, which is used when it is impossible to connect via HDMI output. Connectors of this type are divided into three types: digital, analog and combined. However, transmitting sound through this connector is not as simple as with the previous one, since it all depends on the video card used in the computer, because not all of them support audio playback through the DVI output.

In the case of transmitting not only audio, but also video signals to the TV, you must use a DVI - HDMI cable or connect devices using DVI-D - HDMI adapters, and then an HDMI-HDMI cable. This complex connection system is explained by the fact that the video signal does not always pass through the DVI cable.

The disadvantage of this method is also the complex setup process compared to the previous option. To begin, in the TV menu you need to select the DVI connector as the signal source, and the computer and TV must be connected to each other.

Connection via VGA cable

This is an outdated method that is inferior to the first two in terms of ease of connection and playback quality. Therefore, it is often used in older devices where it is not possible to connect using other cables.

What problems may arise during connection?

Very often, the VGA output is already occupied by a computer monitor, so in order to connect another device you need to purchase a special adapter, and then a cord for audio playback.

Main disadvantages

VGA is not intended for audio transmission; it can only be used as an additional element, to which a special cord must be connected. This option is not only expensive, but also more complex and of lower quality compared to other methods.

How to transfer sound from a computer to a TV via WI-FI

This method places additional requirements on the TV - support for DLNA technology and the presence of a multimedia file player. Modern plasma models are equipped with this function, so this connection method can be considered as an alternative to HDMI.

Connection setup

After making sure that the TV has a built-in WI-FI module, you can start setting up.

1. First, you need to configure the router so that it can work in DHCP mode.

When setting up, you must assign a password that will protect local network from unauthorized entry.

1. In the TV menu you need to find the item “ Wireless connection", and then find your network and log into it using your password.
2. To transfer sound to your TV, you need to install it on your computer. special program- media server. This program then allows access to files and folders containing music or movies.
3. To switch audio from your computer, you need to open the media server and select Ethernet as the playback source on your TV.

What is the disadvantage of connecting via a WI-FI router?

When playing audio to a TV, there is a large load on the local network, which can lead to slower speeds.

Connection via RJ45

When connecting using this method, a special network cable is used, which can be found in stores under the name “twisted pair”. As in the previous method, the TV must support DLNA data transmission technology.

It also uses a router, which is configured in the same way as through a WI-FI connection. However, using this device may result in reduced speed. Therefore, it is better to give preference to an additional network card.

The setup follows the same principle as via WI-FI, but you need to connect through a media server.

How to output sound from a computer via an RCA cable

This method allows you to connect even the most outdated models of computers and televisions. Such a cable is called a “tulip”; it can have two or three sockets, each of which is responsible for transmitting a separate signal. Yellow – video, white – left channel of stereo audio signal, red – right channel of stereo audio signal.

Devices must be disconnected from power before connection. Then, you need to attach the tulip connectors to the corresponding holes (often color coded). After this, in the computer settings you need to expand the desktop to fit the size of the TV screen, and switch the TV to “Video” mode.

The most preferred methods among all those described above are connections via an HDMI cable and via twisted pair or WI-FI router. It is these options that can ensure sound quality and connection reliability at the proper level.

The video shows in detail how to connect a TV to a desktop computer via HDMI and MPF. First you need to select a cable without adapters and make sure that the necessary connectors are available on the devices. Then the connectors are connected, and the TV and computer are configured.

How to connect sound from a computer to your TV

Many music lovers store digital recordings of their favorite tracks on their personal computer, but it is better to listen to them using a modern audio system. Great option This is a home theater - surround sound, the subwoofer produces excellent low bass sound. But how to connect so that the sound goes from the laptop to the TV, and then spreads throughout the room through high-quality speakers? There are quite a lot in various ways, allowing you to solve the question of how to connect sound from a desktop computer or laptop to a TV.

Main connectors

Each household appliance has connectors for connection, the main and quite often used ones are the following.

1. Multimedia interface high definition, abbreviated as HDMI. Its purpose is to transmit digital video and audio data. Recently it has become fashionable to connect with worldwide network through this port and cable.
2. Digital Visual Interface or DVI. It is designed to transmit video signals to all modern monitors and LCD TVs.
3. Video adapter with 15 pins or subminiature VGA connector transmits the audio signal line by line, used on all modern television and audio equipment.
4. Wireless connection or the well-known abbreviation Wi-Fi, which has become firmly established in the lives of modern youth - you can connect to it and transfer data without a cable.
5. Registered Jack (connector) or RJ45 is a connector for connecting a computer or laptop to household appliances.
6. A composite RCA connector patented in the early 1940s to switch the sound from the phonograph of that era to an amplifier. It is still used today.

All modern equipment has several connectors of various types in its arsenal to make connections easier. A DVD player, laptop or other digital media connected through these connectors is ideally combined with the TV for exchanging information.

Connection options

Today there are a huge number of cables on the market that allow you to connect different types of connectors. Each type of connection has its own characteristics.

HDMI cable

This method is considered the most popular because it rarely causes problems and malfunctions, and the quality is at the highest level. A cord of this type is sometimes supplied with digital equipment, and can be purchased retail at any store.

When connecting, you need to turn off the power to the product, connect the cable to the laptop and TV. This connection does not require separate settings; only when you turn it on, specify the source of the audio signal in the TV receiver menu section.

Advice! When buying a cable, do not chase the most expensive analogue - they are all made of the same material, which does not affect the sound range.

During preparation and execution of such a connection, a problem may arise: the sound does not come through the TV acoustics. Go to the laptop settings, select the TV as the audio source, and check the “Use as default” checkbox. Also check your video card - it should support similar playback. True, many manufacturers include a special jumper in the package that helps create the connection; this should be displayed in the instructions. In order for the video card on the TV to work properly, you need to update the drivers, but only from the official website.

When setting up, both products must be connected; if for some reason the laptop does not see TV when the HDMI cable is turned on, restart the computer and repeat all the settings.

DVI

This type is used when you need to switch audio from a computer to a TV. There are three main types of such connection:

• digital version;
• analog method;
• a symbiosis of both options.

The only problem is that this connector does not always transmit sound correctly - the reason is the video card of your PC. Experts advise using a special DVI - HDMI cable or using a DVI-D - HDMI adapter together with a cable where both connectors are identical, i.e. HDMI type. Such a complex diagram of the entire structure has a very simple explanation - the video signal does not in all cases pass freely and without changes through a cable of this type. In addition, the settings have a more complex system than with the first option.

VGA

This is quite an ancient method - it is rarely used and mainly on products with an old layout, where it is not possible to connect modern cables. This connector is always busy system unit cord from the monitor, so you also need to purchase a special adapter and audio playback cord.

The disadvantages include the fact that this outdated cable, connected to products, does not transmit sound according to its characteristics - it is used as an additional element. The option is considered costly in monetary terms, difficult to implement and does not have the necessary quality.

Wireless technologies

Many users often ask the question of how to transfer sound from a home computer to a TV when WI-FI assistance and what you need to purchase for this. Your TV must support DLNA technology - an alliance of digital networks located in the home. This modern project allows the user to solve all problems - download any applications and updates, receive and transmit video images, digital music and distribute it among households compatible devices.

Today, every flat-panel TV of the plasma model family is equipped with such functionality, so this method of data transfer is an alternative to an HDMI cable.

The settings are not complicated, but to complete them you need to buy a high-quality router that works in the DHCP system - a technology that allows you to automatically assign an IP address to any device. When you are convinced that the TV is equipped with a special module, proceed with the step-by-step setup.

1. We configure the router to operate in the mode In this case, it is necessary to set a very strong password (at least 10-12 characters) to protect the device from unauthorized access.
2. In the TV menu, look for the “Wireless Connection” section, find your network and enter it.
3. To transfer sound from a laptop to TV, you need to install the “media server” program on your PC/laptop, then use it to open access to the necessary virtual media in which the music is stored.
4. To switch sound from a PC, you must open it earlier. installed program and in the TV settings select “Internet” as the playback source.

Experts attribute a significant load on the local home network to the disadvantages of this type of connection - this can affect the Internet speed.

RJ45 network cable

This type of cable is sold in retail networks as “twisted pair”. For such a connection, the TV must support data transmission technology similar to the previous option. Additionally, you need to purchase a router, which leads to a slower connection speed - you need another network card. The setup is done in the same way wireless network.

PC+TV via RCA

This method is useful for connecting outdated models of PCs, laptops and TVs, to which modern cables simply will not fit. Experts call this type of connection a “tulip”; the cord may have two or three connectors, each of which is responsible for transmitting specific data or a signal. Standard marking:

• yellow plug - video signal;
• white is the left channel of the stereo audio signal;
• red color - right channel.

Professional masters advise using the HDMI option or a wireless connection; in second place is an RJ45 cable, because only these options can provide high-quality output sound and exceptional reliability.

Some connection options can be seen in the attached video:

How to connect sound from a computer to a TV

A large number of people face the need to connect a computer to a TV every day. This is a very good opportunity, since the size of the monitor and its location do not always allow you to comfortably watch movies and other entertainment programs. In addition, the TV can be used as a monitor if the latter fails.

• 1 Connector types
• 2 HDMI
• 3 DVI, VGA

• 4 Wi-Fi, RJ45
• 5 S-Video/SCART

Connector types

Modern devices for connecting a computer to a TV allow you to do this very quickly, while the image and sound will be of high quality. Almost any model is suitable for such a connection, including old picture tubes. The definition of the process algorithm is directly determined by the type of connectors with which the connected devices are equipped.

The most popular interfaces (connectors) are:

• HDMI;
• RJ45;
• Wi-Fi;
• S-Video/SCART.

After a thorough inspection of the devices and identification of one or more connectors from the above list, you can begin the process of connecting the devices.

HDMI

This connector is considered the most convenient and, accordingly, the most popular. In addition to clear images, it delivers high-quality sound. To connect your computer to your TV, you just need to have a special cord with the appropriate outputs.

First, the connected means of communication are disconnected from the power supply and the cord is connected. Next, the computer and TV are turned on, HDMI is indicated as the source in the latter’s settings. The image and sound will be reproduced without auxiliary operations.

When choosing an HDMI cable, you need to understand that the materials used in its manufacture and, accordingly, the cost do not affect the sound and image quality. Therefore, it is not at all necessary to buy an expensive wire.

DVI, VGA

To connect image and sound from a computer to a TV, you can use other interfaces - DVI or VGA. The first option is more preferable. It is recommended to resort to the VGA-related method only if it is impossible to work with DVI. Often, when a user tries to connect devices using VGA, he finds that he is busy with a computer monitor. This problem can be solved using a DVI-VGA adapter, which makes it possible to make an auxiliary VGA from free DVI. Using these interfaces you can only transmit images; to connect sound to the TV you will have to buy a special audio cord.

Wi-Fi, RJ45

To connect a computer to a TV via a network connector or Wi-Fi, the latter must meet two basic requirements. The first is the presence of a multimedia player, the second is the ability to support DLNA technology. This technology gives devices the ability to exchange files online. Thanks to it, the TV can work with files directly from the computer’s hard drive, without the use of removable hard drives or flash drives.

The connection procedure via DLNA includes two steps:

• connection of communication means;
• installation of the DLNA server and its further configuration.

The first stage depends on whether the TV has an RJ45 network connector or Wi-Fi module. Some models have both of these options at the same time. It is best to use a network cable to connect video and audio.

To connect the network connector of the TV to the router, you will need a “twisted pair” cable - a special cable. Finding such a cord is not difficult. However, the router option is not possible in all cases. Reason: video and sound on the TV puts a large load on the router, which leads to Internet failures (reduced speed or loss of connection). Solving the problem by purchasing a more productive, expensive router cannot be called optimal. It is better to install an additional network card, which will save money.

After connecting, proceed to install the “Home Media Server”, making the appropriate settings. To play video and sound, you need to open “ Home media server" and run it. Next, you need to select Ethernet as the playback source on the TV, after which the explorer opens and the desired file is selected.

S-Video/SCART

With help this method You can connect audio and video even to an old TV. The main condition here is the presence of an “s-video” connector on the computer, and a twenty-one-pin wide scart connector on the TV. You also need to buy an “S-Video” cord and a “SCART–audio/video/s-video” adapter.

The connection process algorithm is as follows:

• The adapter is inserted into the TV connector. If there is a switch, the latter is placed in the Input position;
• connection of connectors;
• to transmit sound from a computer, you need to connect a special “two tulips” cord to the appropriate connectors of the adapter;
• the TV turns on;
• The computer turns on. After turning it on, the “Properties” item is called up, where “extend the desktop to the selected monitor”;
• After switching the TV to “Video” mode, the computer desktop is visible on the screen. Next, open the file and use the mouse to move the player window onto the TV, switching it to “full screen” mode.

How to connect sound from a computer to a TV: 3 nuances

To connect sound from a computer to a TV, you don’t need to buy expensive technical devices We all love to watch the latest in the film industry, but a standard PC monitor screen is clearly not a replacement for a large flat-screen TV. That is why today more and more craftsmen connect a computer to a TV and watch movies on the big screen. In general, the connection task is quite simple, but problems with sound often arise. A trivial but very problematic question - how to output sound from a computer to a TV?

Let's first figure out in what cases you should switch the sound from a laptop or PC to a TV. So, if you have both a computer and a TV nearby in one corner of the room, then it is not necessary to switch the sound to the TV. The picture can be displayed on a large screen, while the sound will continue to flow from the computer to the speakers. It’s a completely different matter when the computer speakers and the TV are in different corners, or, what’s even more trivial, you don’t have a good audio system and the sound from the TV is much better. It is in this case that you need to connect the sound from the computer to the TV, in other words, output it to another device.

To output sound from a computer to a TV, you need to connect them together using a cable

The completion of the task depends on the following nuances:

1. Your software. Connecting sound on older operating systems often occurs in automatic modes. In new systems, such as Win 7,8,10, you only need to manually transfer the sound to another channel.
2. Connection type. Sound, like pictures, can be output to a TV through a number of methods. We will look at each option in detail later.
3. TV type. Depending on the model, you can make the connection active through the device menu or in automatic mode.

How to connect audio via HDMI to your TV

In general, connecting sound and pictures from a computer to a TV can occur in three main formats - via HDMI, DVI or so-called tulip cables. The very first type of cable is the newest, it is compact, easy to use and versatile - high-quality video and audio are carried through one connector. All you need to do to transfer sound from your computer to your TV is turn on the desired movie and set the appropriate settings in the menu.

Before playing the movie, you need to turn off both devices, connect one end of the cable to the HDMI socket on the computer and the other end to the corresponding socket on the TV panel.

Depending on the model of the latter, you need to either switch to HDMI mode or wait until the device itself recognizes the connected computer. Next, everything that is shown on the TV should be displayed on the TV screen.

What surprises could there be? In general, the problem with sound in almost 90% of cases boils down to one thing - you need to enable audio playback via hdmi on your computer. Otherwise, the video will go to the TV, and the sound, for example, to headphones connected to the PC.

The solution to the problem is simple:

• Right-click on the sound volume icon in the lower right part of the WIN taskbar (next to the time);
• Go to the “Playback Devices” menu;
• Select HDMI or TV from the suggested sources (the PC often detects the device to which it is connected);
• Press required device right-click and select it as “default device”. At the same moment, the sound will start coming to the TV.

You can buy an HDMI cable at any store that sells computers or household appliances.

If you connect your PC to your TV via a VGA cable, the procedure is the same as with an HDMI cable, but the picture quality will be slightly worse. However, in the case of connection through the so-called tulip, everything is a little more complicated. let's consider this type connections in more detail.

Using a tulip: how to connect a PC to a TV

In general, all modern TVs have long had connectors for connecting with new types of cables. However, if you have an old TV, you will have to connect it to the computer via the so-called “tulip” cord. It is a bundle of three cables of different colors - yellow, red and white. The cable was jokingly nicknamed a tulip because of its multi-colored appearance. So, in this bunch of “colors” the yellow cable is responsible for the sound, white for the left speaker and red for the right. This is one of the very first systems for outputting sound and video from one device to another.

The connection is as follows: insert cables of a certain color into the corresponding sockets on the TV and PC (sockets of the same color). Switch the TV to Video or RCA mode and switch the audio output on the computer via RCA.

The downside is that you won’t be able to output a high-quality HD picture through such an outdated cable, and you’ll have to forget about surround sound – a maximum of two speakers. The second problem is that most computers no longer have cinch connectors. And while sound can still be output through the tulip, for example, through a headphone or speaker jack, modern video cards do not transmit video in this way.

Everything in its place: how to switch sound from TV to computer

If you have finished watching a movie and want to return to PC mode again, you must first disconnect the cable through which the devices were connected, and then switch the computer to play sound through speakers or headphones. You can do this in the sound control manager, where you select the default device desired channel, for example headphones.

After connecting the cable, you need to turn on the sound in the corresponding menu

It's worth noting that it's easiest to make the switch if your computer and TV have connectors for an HDMI cable.

In this case, you won’t have to disconnect the wires for a long time and worry about settings, sound and video quality. All you have to do is unplug the cable and switch the sound source. By the way, on new Windows Most often, when the cable is disconnected, the PC itself will switch to standard playback mode.

Instructions: how to connect sound from a computer to a TV (video)

Well, getting sound from a computer to a TV today is not difficult. There are several types of connecting a PC to a TV - HDMI, DVI and tulip. The first method is the newest and allows you to transfer an image to high resolution and surround, multi-channel sound, in addition, via HDMI, the connection occurs with one cable. DVI is a slightly more outdated technology, the picture quality will be average, but the connection is also made with one cable. A tulip is three cables at once, and not all PCs already have connectors of this old type. You need to switch sound from your PC to your TV in new operating systems in the sound manager menu, which can be found in the taskbar in the lower right part of the monitor screen, next to the time and date.

2 When connecting via DVI, some video card models also support audio transmission, then when using a DVI-HDMI adapter, both video and audio will be supplied to the HDMI TV input. If you have only digital DVI on your video card (then written with the letter D), then you will not be able to connect an adapter to VGA to it, because there are no analog signals there. But if the video card has two DVI connectors, then they are written with a prefix in the form of the letter I and mean a universal port that transmits both analog and digital video signals. You can connect receivers of both analog and digital signals to such a video card. Visually on the connector only with digital signals Four contacts around the horizontal slot are missing. In universal DVI-I connectors, all contacts are present. DVI-D connectors are rarely found on modern video cards; they mostly come with universal DVI-I connectors.

3 When connecting via a DVI connector, you need to pay attention to the presence of the HDCP (content copy protection) function. Some TV models will refuse to work with this type of connection without HDCP. This is especially true for playing Blu-Ray discs.

4 If you connect your TV to your computer as a second monitor, then the monitor and TV must be configured separately. In this case correct setting The screen will say “Extend the desktop onto this monitor”. You can display the settings of the program playing the video on the monitor, or continue working on it while watching a movie on the TV screen.

5 Blu-ray and HD-DVD discs are currently actively replacing DVDs. These discs contain films in a special film format – 24 frames per second. Moreover, if the computer uses a frequency of 50-60 Hz, the image “slows down”. The picture will be as clear as possible if you switch the video card to a refresh rate of 24 frames per second. However, this can only be done if the TV supports 24p mode.

Connecting audio from a computer to a TV

1 To get sound from AMD/ATI video cards, in the “Sounds and Audio Devices” control panel settings of your operating system(WinXP), you need to select the default audio output device "ATI HD Audio rear output".

2 When connecting some video cards, there may be no sound with an HDMI-HDMI cable. There may be no sound on the video card itself, and you need to connect sound to the video card from the motherboard from “SPDIF out” (motherboard) to “SPDIF in” (video card) using a special short cable (must be supplied with the video card). After that, connect the HDMI cable to the HDMI ARC input of the TV, and in the computer settings “Start-Control Panel-Sound-Digital Audio” make S/PDIF used by default. Uncheck the “disable digital output” checkbox. And read the manual carefully motherboard and video card.

3 When poor quality Sound check in the settings of the sound card or player for stereo or 5.1 or some other sound output. Try changing the output from one mode to another.

4 When connected via DVI, sound can be supplied from the miniJeck on the computer to the “Audio DVI in” input, not to be confused with the Audio in input for a composite signal. If after this there is no sound, then look at the sound settings on the TV, maybe you need to switch the input.

5 In some models of sound cards, in rare cases, in order to supply sound to the TV, you need to pull out the speaker and headphone connectors from other connectors.

6 When connecting a video signal via a DVI-HDMI cable, some TV models will also take sound from the HDMI input, but the computer does not produce sound via DVI and, according to all the rules, the user connects the sound with a separate cable. So, to play sound, you may need to additionally indicate in the TV menu that for given input HDMI needs to take sound from another input.

7 When using DVI-HDMI adapters, it is better to use it on the computer side and connect an HDMI-HDMI cable to it. This is the case when using video cards that mix the audio signal into the DVI using S/PDIF. If you use a DVI-DVI cable and there is already a DVI-HDMI adapter on the TV side, then the sound may not pass through, because there are three types of DVI connectors (digital, analog and combined) and the cables are different and where the video card mixes the sound, to which We don't know the contacts. Or maybe the cable just doesn’t have the contacts that are needed to transmit sound? The DVI-I dual link cable has the most complete set of conductors inside, but the rest need to be looked at.

8 Some TV models have an “Audio HDMI” menu item. When enabled, audio will only be taken from the HDMI input when an HDMI cable is connected. You need to know this if you are using a DVI-DVI cable, and there is a DVI-HDMI adapter in front of the TV and the sound is supplied via a separate cable. So, with this connection and the “Audio HDMI” item is active, there will be no sound on the TV. When you disable this menu item, the sound should work.

9 Sound, if not on the video card, is taken from the output of the sound card.

10 It happens that the sound does not pass through due to incorrect input/output settings in the sound manager on the computer. One inconspicuous item in the menu can ruin everything, look carefully at all the settings of the video card, sound card and player.

11 In Windows XP, problems often arise with the SPDIF setting. The fact is that in this OS the digital output is not displayed as a separate audio output device. Therefore, where the sound goes depends on the driver. As a rule, analog and digital outputs are either duplicated, or when a digital output is connected, the analog one is disabled.

12 ATI video cards already have their own sound controller built-in, so no other sound devices are required. In case of audio output via the DVI connector, you must use a proprietary DVI->HDMI adapter. Check the availability of the adapter in the kit directly at the store where you make the purchase - equipment may vary! You must use the adapter that comes with your video card. Left adapters, as well as DVI->HDMI cables, will not work. The "correct" adapter contains a chip with a number sewn into it.

13 Mobile NVidia video cards 8xxx series and higher support audio transmission via HDMI according to the same principle as ATI discrete video cards, i.e. have their own sound controller, which is defined by the system as a separate audio output device (Realtek HDMI Output). As for the supported formats, it is reliably known about the output of 5.1-channel audio.

14 If you are sure that you have configured the system correctly, connected the bridge in NVidia, installed the driver for ATI, but the sound still does not appear, open the instructions for the TV and check whether you need to specifically select audio reception via HDMI in the TV menu, and what formats digital audio supported.

15 If we want the sound to go to the TV only when watching a movie, then select the analog output as the default device (as usual). And in the settings of your player, through which you watch movies on your TV, select SPDIF (for NV) or Realtek HDMI Output (for ATI), respectively.

We output sound to two devices using the program

I stream on my channel zakrutTV and one day I needed output game sound to speakers and headphones simultaneously.

The thing is that I use and therefore I need to transmit the game sound to the second computer and to the headphones at the same time.

There are very simple program, which is called " Audio Repeater"You can easily find it on the Internet.

After successful installation, you will have two virtual audio devices. Next install " Line 1"as default device in settings" Sound" - "Playback".

Now run " Audio Repeater (MME)" from the start menu.

Set to field Wave in device " Line 1", and in the field Wave out device " Speakers". Click "Start".

Now let's connect the second device (headphones). Repeat the previous steps, only now set it to the field Wave out device " Headphones".

That's all, now the sound is broadcast to two devices (speakers and headphones). Window Audio Repeater (MME) you can collapse them, after which they will appear in the panel with hidden icons (in the lower right corner).

Yesterday my wife and I decided to watch a movie, but in order not to disturb anyone, we had to distribute the sound simultaneously to two pairs of headphones. Some headphones are simple wired ones, which simply intercept the sound from the speakers when you connect them to the laptop, and the second ones are wireless Qumi Concord connected via bluetooth. Is it possible to do this using standard Windows 7 tools?

It turned out that it was quite possible. Most computers these days come with built-in sound card from RealTek. It requires native drivers to be installed on it, not even necessarily the latest ones, but not the ones that come with Win7 out of the box.

Now I only have sound from the speakers, and the microphone is used from wireless headphones. Open the Recording tab.

Then we turn on the display of all devices, even those that are disabled according to the system.

I have a supposedly disabled software Stereo Mixer on my sound card. After which it needs to be turned on.

And choose to have it play on your second audio output device. In my case it's wireless headphones. After which the system will simultaneously output sound to the speakers (or the first headphones) and additional device, for example wireless.
