There is no sound coming from the speakers. Solving the problem with the disappearance of sound. The speakers are connected to the microphone jack

All electrical and radio equipment is prone to failure. This happens for various reasons - the service life has expired, improper operation, poor build quality, spare parts, etc. Next, we will look at what to do if the speakers on the computer do not work, namely, the sound has disappeared, only the right (or left) speaker plays, or extraneous noise has appeared from inside.

Types of faults

If the sound of the speakers on the computer disappears, then the malfunctions may be of the following nature:

software;
hardware.

In the first case, the sound does not work due to sound driver your device. Perhaps, after installing the Windows operating system (it doesn’t matter XP, 7, 8 or 10), you did not download additional drivers responsible for sound playback. All you need to do is go to the official website of the company to which your sound card belongs and download the latest updates.

Hardware faults are much more complex and require some radio and electrical skills. In this case, you will need to use a multimeter to check the functionality of all internal elements of the audio devices in order to accurately determine why the speakers on the computer are not working.

Reasons for failure

The culprits that the sound on the speakers does not work if they are turned on may be the following factors:

Low cost of devices, which indicates poor quality assemblies.
Speakers and other circuit elements wear out over time.
Failure to comply with operating requirements: air humidity and room temperature do not meet standards.
Damage to the insulation of conductors as a result of mechanical impact (the wire was accidentally broken).
Problems with your computer's sound card
Problems in software

To determine the exact cause of the breakdown of the speakers on your computer, you need to carry out several simple measures and, using the method of elimination, find what exactly is not working.

Major breakdowns

Among the most popular breakdowns computer speakers highlight:

Video repair instructions

So, we have looked at the main malfunctions of audio speakers. Now, I would like to provide you with tips for repairing speakers on your computer with your own hands:

If the sound suddenly disappears, check that everything is connected: the plug has not fallen out of the socket or the electrical plug has fallen out of the socket. There are frequent cases when the reason is precisely such a simple circuit break.
If music is playing, the light is on, but there is no sound, check the volume control, it may be at the very minimum (MIN mark).
To check whether the problem is in the speakers, connect headphones to the system unit. If it happens that the speakers on the computer do not play, but the headphones work, then the reason is definitely in the speaker system.
If only one speaker (right or left) is working, check the sound balance in the settings; it may be biased in favor of one of the elements. If you are sure that two devices are turned on, you can also move the plug (pull it out and reinsert it into the socket), because sometimes the cause is poor contact. You can adjust the balance in this window if you have Windows XP installed:
If you decide to replace the plug, while leaving the old wire, use exclusively soldering. There should be no terminals or twists.
If noise occurs in the speakers, check the integrity of the speakers (they could be torn, as in the photo below), as well as the quality of the connection between the plug and the socket. Another likely reason is a failure in the system’s audio settings.
If you don’t have a multimeter, you can check the performance of the speaker with a regular 1.5 V battery - when you connect it, a characteristic rustling sound and a shift in the diaphragm should appear.
Another test option is to connect the audio system not to the computer, but, for example, to a DVD player or telephone. If sound appears, it means the problem is with the PC sound card.

That's all I wanted to tell you about why the speakers on your computer don't work and how to repair them yourself. We hope that now you can independently find the cause of the breakdown and eliminate it without much difficulty!

A fairly common situation is loss of sound on a personal computer or laptop. The article below will tell you how you can try to identify the problem yourself and solve it without involving any computer experts.

First, you need to determine why there is no sound on the computer. In most cases, the problems are as follows:

Problems with speakers or headphones - from a poorly connected wire to their breakdown;
Problems with the software - from incorrect settings to drivers sound card;
Sound card malfunction - in most cases, only repairs under warranty or repairs at your own expense in specialized service centers will help here;

Problems with speakers or headphones

The first thing to rule out is a malfunction of the sound output device. To begin with, it would be a good idea to check the wires - whether they are connected correctly and whether they are fully plugged into the connectors they need. The sound card connector into which you need to plug in speakers or headphones is usually green.

If everything is plugged in correctly, but there is still no sound, it would be a good idea to check the sound through some other speakers or headphones, thereby completely eliminating the possibility of a breakdown of the audio output device. If there is still no sound, then the problem is in the computer.

Problems with the software

It is quite possible that the system has some problems with the software - incorrect settings or “lost” drivers.

“Incorrect settings” means incorrect volume settings in the system.

In order to make sure that the sound settings are not at a minimum, you need to click on the sound icon in the tray (in the form of a speaker) and look at the position of the volume slider.

If the volume is set to 0, then this is equivalent to muting the sound in the system. In this case, you need to set the volume higher.

For various reasons, problems with drivers may occur on your computer - for example, due to viruses, or some kind of system failure. You can check the audio driver status as follows:

Reinstalling the driver

The very first thing you need to do is find required driver. Most often the most in a simple way will find it on the disk that came with the computer.

As an example, the photo shows the disk that came with the motherboard.

You can also download the required driver from the Internet; for this you need to know the model of your sound card. In most cases, it is built into the motherboard, so you can easily find the necessary information on the built-in sound card on the Internet.

Installing the Realtek sound card driver

In the majority modern computers The sound card manufacturer is Realtek. You can download their sound card driver. To start downloading, you must first tick the “I accept to the above” box, and then click the “Next” button. Then, you will need to select the desired driver by bit size operating system(You can find out by opening "System Properties").

For 32-bit (86-bit) operating systems Windows Vista, Windows 7, Windows 8, Windows 8.1, Windows 10, you need to download drivers called " 32bits Vista, Windows7, Windows8, Windows8.1, Windows10 Driver only (Executable file)"
For 64-bit (64-bit) operating systems Windows Vista, Windows 7, Windows 8, Windows 8.1, Windows 10, you need to download drivers called " 64bits Vista, Windows7, Windows8, Windows8.1, Windows10 Driver only (Executable file)"
For the Windows XP operating system, you need to download drivers called " Windows 2000, Windows XP/2003(32/64 bits) Driver only (Executable file)"

To load the selected driver, you must click on the "Global" button in the same line.

You need to run the downloaded file and follow the simplest instructions in Russian - in short, you just need to press the “Next” button all the time. At the end of the driver installation process, you will need to restart the computer, and then check whether the sound problems are resolved or not.

If all else fails

If checking audio output devices (speakers/headphones), checking volume settings and reinstalling the driver did not help, then it is quite possible that the problem is already at the hardware level. In any case, it would be a good idea to contact a service center, where they will carry out diagnostics and identify the problem.

The audio output device is an integral component when working with a computer. Usually connecting such devices does not cause any problems at all, but what should you do if problems do arise? How to connect speakers on a computer without problems? No sound, won’t turn on - this is the most common problem when pairing an audio system with a PC. But what can cause problems? How to setup? What to do if there are no sounds or music playing? We need to figure it out. In order to find a solution to a problem, you need to get to know the causes of the problem. There can be a lot of options, and you need to know about each of them. Today we will talk about six reasons why there is no sound.

Non-working speakers

Checking the integrity of the audio system is the first thing the user should pay attention to:

There are such incidents when the user, in a hurry, simply forgets about the wires.
There is a high probability that the connection was made incorrectly. In other words, the wires are connected through the wrong input. The point is that the audio card personal computer There are several outputs: for recording devices and for audio output devices. The output for the microphone is pink, and the output for the speakers is green and they are connected to the same color. Pay attention to this so as not to confuse anything.
Also, often the entrances could simply become loose due to frequent use. To fix this, simply correct them. At the same time, it wouldn’t hurt to clean the connectors from dust.
Look at the front panel of the audio equipment. If the LEDs do not light up, then the speakers themselves are not powered. Sometimes users simply forget to turn on the device.

Of course, all of the above problems are elementary, but most often the problems are connected precisely with this.

Sound is turned off or turned down in settings

How to install sound on a computer? Perhaps the problem lies in the operating system settings. To check this:

Click on the “Start” button and go to “Control Panel”. There you need to find the “Equipment and Sounds” section.
Now you need to go to the “Sounds” tab. This should display your audio device that is connected to your computer. Select the desired speakers with your mouse cursor and open their properties.
You should see the “General” tab, in which you need to make sure that the devices are defined and enabled.
Next, go to the “Levels” tab. The current volume gain will be displayed there, which should be more than 80-90%.
Go to the “Advanced” tab and activate the sound check. If you don't hear anything, save your settings and move on.
Try going back to “Volume Settings” and look at the sound level. It may be turned off or reduced to minimum.
Right-click on the speaker shortcut, which is located in the lower right corner near the time. Check the current volume level there.

Important! Don't forget about the speakers themselves. There is a possibility that the volume control is set to minimum.

Drivers

How to install speakers on a computer if they are already connected to it? There may be no sound due to the fact that the appropriate drivers are not installed on your PC. To determine whether the correct driver version is installed:

Visit “Device Manager”, which is located inside the Control Panel. You need the “Sound, Game and Video Devices” tab. If the audio card is connected to the computer, it should be displayed here.
If there is a yellow or red icon next to the devices, then the driver is faulty or missing altogether. We recommend using the Everest program. With its help, you can find out the model of your board and download the necessary software for the speakers.
It happens that the card is installed, but the Windows operating system does not want to see it. The root of such a problem could be anywhere. The device may be faulty or not connected correctly.

Important! Most The best way- this is to clean the system unit from dust and blow out the slot. In other words, the problem is related to the computer hardware, and if cleaning does not help you, we recommend using the services of a specialist.

Video material

This information should help you install speakers on your computer. Take your time and be careful, then you will definitely succeed.

The most common reason no sound - turn it off or set the volume to minimum. If there is no audio playing on your computer, hover over the speaker icon in the tray (right corner of the taskbar). The tooltip will indicate the current volume value. If the sound does not play in a separate application, check its settings. If it is enabled in the settings, audio playback in a specific program may be limited in the mixer. To check, right-click on the speaker icon and select “Open Volume Mixer.” There you can turn on the sound and adjust the volume level for each program running on the computer.

Check the volume on the playback devices themselves: headphones or speakers. When using speakers, also make sure they are connected to power and the power button is in the active position. Checking speakers or headphones is quite easy. To do this, just connect any other device to the audio output instead of a computer: a smartphone, a player.

Important! Also check your speaker settings. To do this, go to “Playback devices”, and in context menu speakers or headphones, click “Properties”.

Incorrect operation of audio drivers

Another common reason why there may be no sound on a computer is missing or damaged audio drivers. To identify this issue, hover over the audio icon in the tray. If the message “No audio output device is installed” appears, the problem is caused by the audio drivers.

To resolve these difficulties, right-click on the same icon and select “Detect sound problems” from the context menu.

This will open a troubleshooting window. Wait while the audio diagnostics run on your computer. Depending on the speed of the device, the process can take from a few seconds to a couple of minutes. If the determination of the cause of the malfunction stops at one place, click “Cancel”.

When the sound diagnostics are completed, the system will offer you a choice on which device you want to troubleshoot. In this case, you need to note the device used based not on its type, but on the location of the audio input. For example, if your speakers are connected through the audio input on the front of your computer, check the second box even though it says headphones.

If there is a hardware fault, the diagnostic result will be the following window. It may indicate damage to the speakers or headphones, but most often the cause of difficulties in the operation of audio devices is broken or damaged connecting cables.

At the last step of sound diagnostics, the result of its execution will be displayed. If the problems are resolved, close the troubleshooter. If the diagnostics did not help, click “View additional options.” You can also find help information about the causes of malfunctions by clicking on the “View additional information” link.

Incorrect connection or installation of the device

Sound may not work due to improper connection or installation of audio devices. To resolve this issue, check that the correct input is selected to connect your device to your computer. Speakers or headphones may be connected to the microphone input, causing them to not work.

Go to “Control Panel -> Device Manager” and check the status in the “Sound, Game and Video Devices” menu. If a yellow mark with an exclamation mark appears next to the name, the cause of the problem is incorrect installation or malfunction of the device

Note! If your audio hardware is not showing up in the manager at all, update the configuration in the Actions menu.

Press sound equipment right-click and select “Properties”, then go to the “Driver” tab in the window that opens. To update the configuration, click the "Update" button. Here you can remove the driver to reinstall it later.

In the next step, select where you want to search for sound drivers. Two options are offered: automatic search, which includes a search on your computer and the Internet, as well as a simple search for drivers. It is recommended to select the first option to detect drivers.

Important! If the sound card is outdated and its driver is on a separate disk, first copy it to your computer.

The scanning will take about 20-30 seconds, after which a message will be displayed in the search window indicating the successful installation of new audio drivers. If the device already has the latest available driver installed, the configuration will not be updated.

If updating the drivers did not bring the desired result and the device still does not work, it is recommended to remove it from the system. To do this, right-click on the name and select “Delete”. Confirm the deletion in the dialog box by clicking "OK".

After this, you need to update the list of equipment in the “Action” menu. A search will be performed for devices connected to the computer. If required device is not displayed after searching, restart the manager.

When the speakers are found, their installation will begin automatically. This process may take several minutes. When finished, a message will be displayed indicating that the speakers have been successfully connected and are ready to use.

Damage to connecting cables

Standard 3.5 mm connectors can fail as a result of mechanical damage. Typically, failure occurs at the base of the connector - at the junction with the audio cable. The break may also be in the cord itself. The cause of damage is most often pinched by furniture (table legs, chair wheels). The cable can also be chewed by pets. You can diagnose a breakdown visually or by connecting another cable to the speakers.

Physical breakdown of audio equipment

There may be no sound on your computer if the speakers or headphones you are using fail. This is not difficult to determine - just connect another audio device to the same audio input. If it works, the reason is the broken speakers, and not the computer settings.

Windows Audio service disabled

Another common reason for no sound is disabling the Windows Audio service. This background process is responsible for processing audio data and is always running by default on a running computer. But when changes are made to the system parameters, incorrect parameters may be specified. windows settings Audio. The service can also be disabled by malware.

To check the status of a service, right-click on the Start menu and click on Run. In the text field of the window that opens, enter: “services.msc” and click “OK”.

Note! You can also use the keyboard shortcut “Win+R” to open the “Run” window.

A table of local services running on the computer will open. Find the “windows Audio” item in the general list, check the service status and startup type. Correct values: “Running”, “Automatic”. If the parameters are different, double-click on the selected line to change them.

From the drop down list select automatic start and click “Start” for the service to start working. Confirm the changes by clicking the "OK" button.

Important! Among the proposed options, there are two ways to automatically load the service. For proper audio operation, it is not recommended to select delayed start.

The service will open, after which you can test the sound. If you can't start Windows Audio, restart your computer to automatically load this background application.

No sound on the computer! How to fix?

What if there is no sound on the computer? I think every PC user has encountered such a problem related to the lack of sound on their computer. Greetings, dear readers, to my blog!

In today’s article I would like to pay special attention to the problem associated with the lack of sound on the computer, or more precisely, we will look at the most likely reasons why the sound disappears on our computer and, of course, we will learn how to independently eliminate the problems that arise Problems.

First of all, I would like to note that the problem of no sound on a computer has been, is and will remain a very extensive topic for discussion on the Internet. Therefore, it’s no secret that the general principle of restoring sound in a computer comes down to the fact that you will need to perform (check) a number of specific actions that will be aimed at restoring sound.

Moreover, it doesn’t matter if you are even a novice user, because sometimes even experienced users have to spend a lot of time troubleshooting problems associated with the disappearance of sound in the computer. However, what if you have no experience at all in troubleshooting this type of malfunction? In the literal sense of the word, you can say that you just recently bought a computer for yourself and are starting to master it, and then BAM the sound on the computer has disappeared.

In this case, so that you can find out the cause and eliminate it yourself, today’s article will be not only useful for you, but also instructive because you will learn a lot interesting information. Here we go?

No sound on computer

So, when you turn on your computer, you discover that there is no sound on the computer, and you immediately wonder why there is no sound on the computer? At the initial stage of determining the cause of the lack of sound, it is important for you to know that the lack of sound on the computer can be caused by a malfunction either in the software or in the hardware.

A malfunction in the software part can be caused by a system failure, which in turn leads to damage system files responsible for sound reproduction. You can also add that a malfunction in the software part may be due to incorrect settings of the sound circuit, missing or damaged audio device driver. Another reason may be failed components (sound speakers, sound card). And don’t be too lazy to read the article:

Is your computer slow? Then come here!

Well, dear friends, I suggest you step by step consider the main reasons that may be causing the lack of sound on your computer. We will start, of course, with the simplest.

Step one. You should check the switch on the speakers, and if it is disabled, turn it on. Almost all speaker models are equipped with an LED that lights up when the power to the speakers themselves is turned on.

Also check the position of the volume control.

Step two. Check that the speaker plug is connected correctly to the computer; the plug must be connected to the appropriate socket (the speaker socket is indicated in green).

Sometimes we often notice that some users, after performing computer maintenance or, for example, after moving the computer to another room, inadvertently connect the speaker plug to a completely different socket on the computer or even forget to plug in the plug altogether.

Therefore, there is no need to rush, do everything carefully and carefully, without rushing.

Step three. If the speaker plug is connected correctly and there is still no sound from the computer, then you should check the speaker status in the taskbar. To do this, double-click on the speaker icon as shown in the figure below and make sure that the speaker status is active and the volume slider is not set to the minimum position.

Step four. At the next stage, you need to make sure whether the speakers are working at all, because if the power indicator is on when you turn on the speakers, this does not yet tell us that the sound speakers are one hundred percent working. You can also connect headphones to your computer and check for sound. In general, don’t be lazy and check the functionality of the sound speakers on another computer or laptop.

Step five. Let's say that the sound speakers are fully operational, but there is still no sound on the computer. Then, in this case, you should open the task manager and check the status of the audio devices, or rather, make sure that the drivers for the audio devices are working properly and not damaged. In short, all devices must be recognized by the system, and the status of each device should not be indicated by an exclamation mark.

It is most likely that the drivers were damaged by viruses or malware, therefore, before installing the driver, it is recommended that you scan your computer for viruses.

If in your case there are exclamation marks next to the audio device, as shown in the figure above, then you should install the driver.

Read the article “Checking your computer for viruses” in order to correctly check and scan your computer for the presence of malicious code in the system.

If no viruses were detected, then you should proceed to installing the driver. You can find drivers on the disk, which in most cases come complete with sound or motherboard. You can also install the driver using the ID equipment code. You can find out more about how to install a driver using a device code by reading my article:

Search for drivers by device code

and the status “device is working normally” is displayed in the “General” tab

then you need to use the built-in diagnostic tool, which is present in the operating room windows system 7.

In some cases, audio problems that have arisen can be completely eliminated thanks to the diagnostic tool. Open the control panel, then follow the link “System and Security” => “Support Center” => “Troubleshooting”.

In the window that opens, click “Hardware and Sound”

and select “Play sound”.

Then a window will open in which you will need to launch the diagnostic tool by clicking on the “Next” button. If any faults are identified during the diagnostic process, then at the end of the diagnostics a list of fault detection and correction will be presented in the corresponding window.

Step seven. I once lost sound on my computer for the simple reason that all playback devices were turned off. Therefore, you should definitely check whether sound devices are enabled in the “Hardware and Sound” control panel. To do this, you need to right-click on the speaker icon, which is located in the lower right corner of the control panel, and select “Playback devices” in the menu that appears.

In the “Sound” window that opens, in the “Playback” tab, the device status should be marked with a green checkmark, as shown in the figure below

If none of the playback devices are displayed in the tab that opens, then you should right-click on the free part of the space and click “Show disabled devices” in the menu that appears.

At this moment, disabled devices should be displayed, which should be enabled by right-clicking on them and selecting “Enable” in the context menu.

As a result, the playback device status will be marked with a green checkmark. All you have to do is save the completed procedure by clicking on the “Apply” and “OK” buttons.

Step eight. If, as a result of the above steps, there is still no sound on the computer, then the next step is to check the appropriate settings in the computer’s BIOS. Now I won’t tell you how to enter the BIOS of your computer, since I already told you in the article:

What is BIOS, secrets in the settings

The only thing I would like to add is that you will need to check that the High Definition Audio parameter in the Advanced tab is enabled (depending on the BIOS version, the location of the parameter may differ, so to more accurately determine the High Definition Audio parameter on your computer, use your reference literature motherboard), that is, the value was set to “Enabled”. Then restart your computer and check if there is sound on the system.

Step nine. One of my friends once asked me to fix the sound on his computer; according to him, the sound on the computer suddenly disappeared after installation special program to improve the sound quality, which he downloaded from the Internet. After analyzing the situation and making sure that the lack of sound in the system was caused by the software, I came to the conclusion that the sound was turned off by the windows service. And all because the program that my friend wanted to install was not installed quite correctly in Windows and caused a failure or conflict.

So one of the reasons for the sudden disappearance of sound may be the actions of various malicious programs.

Therefore, if after installing a program the sound disappears, you should think about removing this program. I also recommend that you ensure that the Windows Audio service is enabled. You can check this in the following way. Click on the “Start” button and enter “Services” in the search bar, then left-click on the value found, as shown in the figure below.

Now in the “Services” window that opens, go to the “windows Audio” service.

In the “General” tab, the startup type should be “Automatic” and the status should be “Running”.

If the service is disabled, then you should enable it, save specified parameters and restart your computer.

Step ten. At this step, you should install another known-good sound card, since it is quite possible that your sound card has failed. By the way, before installing a sound card, perform preventive maintenance on your computer, an operation that is very useful and necessary for stable and proper operation of the computer. It is possible that the sound will appear after performing maintenance work. In the article “How to Perform Computer Maintenance” you will learn the nuances that should be taken into account when cleaning your computer.

Step eleven. So, if you still do not have sound on your computer, and you have done all the steps I have given above, then you can try to return the system to its previous state using previously created checkpoints. If you don't understand what I'm talking about, then read these two articles:

How to restore the system and data after a failure

How to quickly restore your computer yourself

After all, it is possible that you lost sound on your computer due to a system file you accidentally deleted that is responsible for sound accompaniment file. Therefore, rolling back the system to a previous state in some cases helps to eliminate problems that have arisen while working on a computer.

Concluding today's article, I hope that the information presented in this lesson was in demand for you and you have learned useful recommendations for yourself. I remind you that if you want to keep abreast of new articles, then subscribe to receive new articles.

And finally, I would like to know from you, what other problems related to lack of sound have you had to fix?

9 reasons why there is no sound on the computer | The sound is gone

Greetings, friends, Bakar Charaev is in touch with you. Today we will look at the question of why there is no sound on the computer, or why the sound on the computer has disappeared? These are the questions that beginners and computer users ask. And our computer desktop is preparing more and more surprises.

Reasons why there is no sound on the computer

The reason why there is no sound on the computer is divided into nine sections. This is from my point of view, since such a problem arises over sets various reasons.

Checking the volume level.
We check your computer for viruses. About how to protect your computer, watch this video antivirusAVG free computer protection and also this video USB Disk Security virus protection.
You need to check your sound device drivers.
Checking the speaker connections.
Configuring system services.
Check if the sound card is enabled in the BIOS.
We eliminate defects in system files.
When connecting to a TV, the sound disappears.
We replace the sound card.

Checking the volume level on the computer

The first thing we need to check is whether the computer is in silent mode.

It happens that you accidentally press a button on the keyboard without sound and wonder why there is no sound. And we also check the volume level on the computer and on the speakers themselves. If everything is fine, we move on.

Checking your computer for viruses

If you surf the Internet on various interesting sites, you download different files and especially without protection, then the probability of computer infection is 100% serious. The virus is working normally on our computer.

If the sound suddenly disappears, immediately check with any antivirus such as avast free.

You need to check your sound device drivers

Sometimes it happens when the system is updated incorrect installation driver or the driver does not work at all. How to find out, look at the picture

In the picture we see a device that shows a yellow triangle with exclamation point. This means that the driver is not installed correctly or is missing altogether. If you have an Internet connection, we update the driver automatically. Right-click on the driver that is not working and select “update driver”

Again there is no sound on the computer, move on to the next step

Checking the speaker connections

I went to buy myself new computer or your first computer, you chose what you needed and came as a lady with a smile on your face. I assembled it myself, connected it to the power source, and look, there is no sound.

When assembling a computer, there are outputs from the sound card on the back of the case and they differ in colors: pink, blue, green, yellow, black.

Pink microphone connector

Blue connector - line input

Green connector - speaker output

Yellow connector - coaxial SPDIF output

Connector black - optical SPDIF output

You need to select the green socket as in the picture.

You need to select the connector where the column is drawn. And also check the functionality of the speakers, connect them to another computer or phone and check whether the speakers work or not.

One more function needs to be checked. We go to start-sound and equipment-sound the window that opens if your speakers are disabled will be gray as in the picture

And if the speakers are not visible at all, then perform the following actions. In the same window, right-click and click “show disabled devices”, then turn on the devices, i.e. speakers and check the sound.

Configuring system services.

If there is no sound on the computer, you need to check the system services to see if they are ok or not.

In order to enter system services, go to Start and write in the search line “services.msc.”

Run the file as in the picture

In the window that opens, look for the file “Windows Audio Endpoint Builder”. Opening this file and look at “the startup type should be automatic” and the state should be “running”. Let's look at the picture.

Checking whether the sound card is enabled in the BIOS It happens that the sound card is disabled in the BIOS system. In order to turn on the card, go to the BIOS and turn on the key as in the picture

After this, there is still no sound on the computer, move on to the next step. Eliminate defects in system files

To implement this method, go to start and call command line. We write “sfc /scannow” in the command line and press enter. The process will start automatic recovery If system files change, it will automatically restore them from storage.

The last reason why there is no sound on the computer when connecting to a TV

This reason also occurred in my practice. I decided to use a TV connected to a computer, I use two monitors on my computer, one standard and the other a TV.

Attention, if you have a weak video card, then when you use a monitor and TV, sooner or later your video card will go to hell and burn out even worse.

I connected the TV and noticed there was no sound. Again I went through points 1.2.3. and found nothing. I went to the control panel - sound and equipment - sound. It turned out that Windows selected the TV as the default device for playback.

If you want the computer speakers to work and not the TV, do the following: on the bottom panel of the desktop, click on the column. Look at the picture!

In the devices section, click on the arrow located under the column icon and select speakers.

If, on the contrary, you want to use the sound of the TV, do the same steps and select the TV, I have it written like this LG TV-3

This is how friends and such pies happen. All possible reasons We looked at why there is no sound on the computer. I hope I wrote everything clearly. If something doesn’t work out for you, write a comment and I’ll try to help you. That's all, sign up and bye!!!

Replacing the sound card

And the last thing to do is contact the service department or buy a new sound card and replace it.

Not everyone knows what exactly to do if there is no sound while the personal computer is running, but the speakers work.

Let's take a concrete and step-by-step look at what to do if there is no sound when the computer is running, but you are 100% sure that the speakers are working. To successfully determine the cause of the problem, if there is no sound and the speakers are working, it is necessary to localize the cause of the malfunction. If there is no sound when the speakers are working, you can select two main search directions:

hardware
program

Hardware problems

First, you need to use headphones to check the functionality of the sound output on the motherboard. To do this, you will have to connect the headphones to the green sound connector (at the bottom of the connector panel, usually the middle one in the row) and check for sound; if there is no sound, this means either a malfunction of the power circuits, a malfunction of the sound card chipset, or the presence of problems in software. This means that working speakers will have to be put aside for now.

But nothing, we unscrew the two screws of the side cover of the system unit and carefully examine the sound card chip (usually soldered directly to system board), if traces of soot or burning are visible, then it is necessary to either buy a discrete sound card or replace the motherboard. If there are no external signs of damage to the chipset (the main chip into which the wires from the speakers or headphones are inserted) of the sound card, you should proceed to the next section of the search.

Software problems

If after these manipulations there is no sound when the speakers are working, then the search for the problem must be continued in the computer’s operating system. To do this, you need to open the control panel -> audio driver and check the status of the sliders responsible for distributing the signal to the sound outputs - volume and signal level.

If there is still no sound, then you need to check the sound system with DirectX self-diagnosis; if there is no sound, but the speakers work, then this may mean that you need to reinstall the audio device driver, the required version of which you can find out from the technical documentation for the motherboard. Usually this is Realtek or C-media.

If after this the speakers work but there is no sound, then you need to check in the motherboard BIOS to see if the built-in sound device is activated.

If after all the above manipulations the speakers work, but there is still no sound, you need to contact the nearest service center for diagnostics, subsequent repairs or replacement of the motherboard.
