It is difficult to imagine a more funny situation than watching the next issue of Comedy club on PC without sound. At the same time, this kind of computer malfunction is far from uncommon in user practice. A great example of this is the irrepressible popularity of questions about how to turn on sound on a computer. Yes, the "unauthorized boycott" announced by your PC is definitely an unpleasant surprise for many novice users. Especially when you consider that the problem with sound is very multifaceted in resolution. However, dear reader, you are in luck again! Because in just a few minutes you will be able to "untie the tongue" of virtually any Windows operating system. Well, let's not waste precious time - let's turn to the experience of professionals.
Diagnostics of computer "muteness"
The answer to the question of how to restore sound on a computer needs to be sought in two ways. The fact is that most often the system "loses its voice" due to software failures. However, the sound may disappear as a result of a hardware failure. For example, an integrated audio chip. To understand what exactly is the cause of the "silence", you need to resort to a step-by-step plan of action. Only after a thorough practical analysis will you be firmly convinced of the type of your audio problem: hardware or software. However, let's not talk about the bad - everything should be decided without the intervention of a specialist.
Step number 1. Elementary check
Tell me how to turn on the sound on the computer if the speakers are inoperative or simply not connected? Of course, no way! Exceptionally simple steps will help you avoid mistakes and wasted time.
First of all, you need to check:
- Are the speakers connected to the PC and the jack used matches the destination device.
- The location of the plug if the speakers are powered from an electrical outlet.
- In what position is the volume control. Perhaps it is twisted "to zero".
- Is one of the connecting cords damaged?
Often just such "platitudes" push a person to wrong actions. Therefore, be careful. Connect speakers that you know are working. Perhaps all your fears are in vain!
Step number 2. Discover the "secret" signs
In the event that the sound on the computer has disappeared, pay attention to the speaker-shaped icon located in the system tray. It may be crossed out to indicate deactivation of the playback device. Move the slider up. If everything remains unchanged, proceed to the next solution point.
Step # 3. Windows services
It's no secret that the operating system has incredibly wide functionality. Management and control in the OS is carried out by special services, one of which is responsible for the playback of audio material. It is simply impossible to fully customize sound on a computer without Windows Audio. Therefore, you need to check the current status of this service.
- Use the Win + R hotkey combination to bring up the Run menu.
- In the window that opens, enter the services.msc command. After confirmation with the "OK" button, you will be redirected to a special section "Services".
- Find Windows Audio in the list provided.
For sound to play and audio settings to be correctly recognized by the system, make sure the service is active. That is, the "Status" column contains the "Running" parameter, and the "Startup type" column is set to "Automatic". You can make the necessary changes using the same right mouse button by placing the cursor on the item that requires the corresponding revision.
Step # 4. The driver that can crash
A crossed out speaker in the tray can also indicate the inability of the special program code that controls the audio chip. In other words, the sound on the computer disappears when the driver becomes inoperable.
- Open the start menu.
- Then go to the "System" section.
- Select "Device Manager" on the left side of the window.
It will not be difficult for you to find the "culprit" of a problematic situation. In the list presented, a non-working device will be marked with an exclamation or prohibitory mark. Update the sound driver using the service disc (software for the motherboard from the kit). In the absence of such, you need to go to the official website of the manufacturer and in the "Support" section download the appropriate modification of your PC software tool. It is worth noting that before installing a fresh version of the sound driver, you must remove the old device control component.
Standard Windows functionality
When all your attempts at practical actions to answer the question of how to turn on the sound on your computer have not brought fruitful results, it makes sense to use the incredibly convenient option "Troubleshooting". However, this functionality is only available in later versions of the Windows operating system. To run this tool for correcting conflict situations, you need to right-click on the conflicting device (indicated by the system with a special warning sign) and select "Diagnostics and correction" in the context menu. In a few minutes the OS will notify you of the result of the work performed. It is likely that such a sound setting on a computer will be an effective salvation for a seemingly "dull" situation.
Step # 5. Settings
If you are convinced that the driver is installed correctly, and the service window of the sound device "Properties" displays the current state "Working normally", then the solution to the question "how to turn on sound on the computer" should be sought by the following algorithm of actions:
- From the Start Menu, select Control Panel.
- Go to the "Sound" section.
- In the window that opens, right-click on the icon of the displayed playback device. Select "Properties" from the context menu.
- While on the "General" tab, pay attention to the "Device Application" item below. More precisely, the value in the checkbox. Apply the On option.
In the case when there are several installed playback devices in the mentioned list, one of them should be assigned the "Default" value.
Step # 6. Audio controller
As a rule, most of the manufactured motherboards have an extended sound scheme. That is, the integrated audio chip can be controlled by a specially installed driver. Let's take a look at an example where the sound setting on a computer is done through Realtek HD Manager.
- Click on the speaker icon (darker in color and slightly larger than the standard Windows volume control).
- In the dispatcher's working window that opens, activate the icon in the form of a wrench (lower part of the interface, on the right).
- In the case when the sound is not reproduced, it is necessary to change the scheme from one value to another (meaning "Front panel of the AC" 97 "and the item of the same name located just below).
Often it is this change that allows you to use the required audio channel.
Step # 7. Incomprehensible multimedia format
There are frequent cases when audio playback on a computer is impossible due to a missing audio codec. This difficulty can be easily corrected.
- Enter K-Lite Codec Pack in the browser search bar.
- Then, from the list provided, select the official source of the product.
- Download and install the required software.
Typically, this action gives the PC "omnivorous" multimedia ability. Rest assured that your computer will not be an exception to the rule.
Step number 8. Software incidents
It so happens that after installing a certain software, the sound disappears, and after uninstalling the conflicting program, it reappears. Some media players play a limited number of audio and video formats. This is the only reason why often unlucky users start to panic. Therefore, before installing any program for viewing and playing multimedia content, you should refer to product reviews and an overview of its tactical and technical capabilities.
Step number 9. Look for the reason in the BIOS
As you know, the BIOS firmware controls and monitors the operation of the entire hardware of a computing device. So installing sound on a computer may turn out to be an impossible mission when the audio functionality is disabled in the BIOS for some unknown reason. However, knowing the main rule when working with the basic system: "Do not touch or change unknown values", you will successfully cope with the task.
To check if the audio function is enabled in BIOS, you need to do the following:
- Log into your PC's Bios.
- Depending on the version of BSVV, the location of the sound "switch" may differ. However, the name "AUDIO" and the value "Enabled / Disabled" or "On" are unchanged.
- Finding a tab with the Onboard Device Configuration option, or High Definition Audio, is not difficult. The main thing is to understand the seriousness of the enterprise and not make rash changes to the firmware. Since it is fraught ...
Step # 10. System Restore
If, after all the manipulations, the question of how to install sound on the computer remains unresolved, then it would be prudent to use the method presented below.
- Go to the start menu.
- Enter "restore" in the search box.
- After the search section is displayed at the top of the service window, press Enter.
- Select the required backup and confirm your choice with the corresponding button.
After a reboot, the system will regain the ability to play sound.
Step 11. Damaged or missing OS files
Sometimes the question of how to make sound on a computer is solved by restoring the lost entries in the system registry. Indeed, very often the user, as a result of erroneous actions (usually in the pursuit of free space on the hard disk), deletes important OS data. Ultimately, the inevitable happens - Windows loses its full functionality. However, the unfortunate user does not always have the opportunity to roll back the system to its original state. By the way, the same well-known reason is to blame for everything - saving space on the HDD, that is, there are simply no OS backups, since System Restore is purposefully disabled. Nevertheless, even in such a situation, there is a way out.
- Press the Win and R keys at the same time.
- In the Run menu, type cmd.exe
- · In the command window, write sfc / scannow.
- Hit Enter.
The damaged data will be restored from the backup storage. It is likely that after rebooting the OS, you will hear the sound greeting again.
Step number 12. Viral infection
Malicious code not only steals and destroys user data. A virus program that has infiltrated the operating system environment can also be the reason for the loss of sound on the computer. In order to identify the pest, special software is required. The anti-virus program, which is traditionally used for protection, is not enough. However, today there are a lot of effective malware killers on the Internet. Therefore, you should not have much difficulty finding the software you need.
- To ensure that your PC never has sound problems, periodically check on the official website of your manufacturer (motherboard manufacturer) to see if more recent drivers have been released.
- When connecting devices for audio playback to the system connectors of the PC, it will not be superfluous to understand in more detail the correctness of the connection scheme involved.
- Often motherboards have special contact pads that can be closed with special jumpers in order to reassign the audio output. Therefore, it is worth referring to the documentation of the motherboard and study the problematic issue in more detail.
- If all methods are in vain in terms of your expectations (which is unlikely to happen), seek specialized help.
How do I connect audio on my computer? As you can imagine, this is an incredibly large-scale question. However, today you have learned a lot of information about what you need to do to "talk" your electronic friend, and what you should beware of during its operation. All the best and pleasant sound experience to you!
The lack of sound on the computer is a problem that users encounter very often. Finding out the reason is quite simple: the malfunction usually lies either in the speakers (or other playback device) or in system failures.
Equipment check
There are 2 connectors on the computer sound card: pink for a microphone and green for speakers or headphones. Make sure that the plug is firmly seated in the correct socket. You also need to make sure that the power plug is firmly seated in the outlet or surge protector. Cables also often fail: they are torn and broken. You need to connect another cord and make sure that the reason for the lack of sound is not in it. It is important to check the volume controls, the power button: the controls must be in an active state.
To understand whether the speakers themselves are in good working order is quite simple: you need to connect them to another computer, laptop or smartphone. If the speakers are working, you should connect another playback device to the PC. There is no sound again - you need to check the connectors of the sound card, the health of a specific computer node or Windows settings.
system configuration
The sound level for each computer is adjusted in the lower right corner of the desktop. If the volume is reduced to zero, no sound will be played.
You can also right-click on the speaker icon and go to the "Open Volume Mixer" menu item. You need to raise the regulators up if they are at a minimum.
By clicking on the same icon, you need to go to the "Open sound parameters" item. On Windows 7 or 10, the audio settings menu looks different. However, the main task is to go into the properties of the output device.
In the "Device Application" column, the speakers must be active. You also need to go through the tabs of the menu that opens and check if the options are disabled. The next step is to go to the properties of the active device and recheck the drivers.
The software version may be out of date or the driver was not installed after updating the operating system. You can download the required program on the official website. Then restart your computer and check if the problem was resolved.
Computer management
Windows Audio is a service with which you can manage audio settings in applications and the OS itself. Restarting this service may activate sound on the PC. This is done in several ways.
Method 1. Right-click on the "Start" menu and select "Computer Management". Click on "Services" and find Windows Audio in the list that opens. This service can be restarted, started, or suspended. You need to go to the drop-down menu in "Properties" and check that the startup type is "Automatic".
Then we do this:
Method 2. Call the "Run" window by pressing the Win + R keys. In the window that opens, enter the cmd command and click "OK". A command line will appear, where you need to write "net start audiosrv" (without quotes) and press Enter. A simple manipulation starts the Windows Audio service, which should help fix audio problems.
Method 3. Go to the "Task Manager". This is done like this: right-click on the toolbar or simultaneously hold down the Ctrl + Alt + Del keys. In the "Services" tab you need to find "Audiosrv" and start if it was disabled. You can try restarting the service.
Equipment check
The sound card is responsible for outputting sound to external speakers. It can also fail, respectively, sound playback does not occur. Neither speakers nor headphones will work when connected to a PC. You need to do the following:
- Go to the "Device Manager" in any convenient way.
- View "Sound Devices".
- If the equipment is defective, an exclamation mark will appear in the corresponding column.
- Try to install the driver on the sound card.
- To restart a computer.
It so happens that the sound card is in the system unit, but the computer does not see it. The equipment may be loose or dusty. You need to clean the system unit, check the cleanliness of the slot under the audio card.
BIOS configuration
Any hardware can be enabled or disabled via BIOS. If you have previously performed any manipulations in the basic I / O system, you need to check if the audio card is activated. BIOS failure can occur without external intervention. You can enter the required software thanks to the prompts that appear when the computer starts up: press the indicated button - F1, F2, and most often Delete. Detailed instructions for entering BIOS are available.
The exact name of the option may differ depending on the BIOS version. The options are HD Audio or High Definition Audio. Usually the desired setting is found in the "Advanced" menu item. Opposite the option must be "Enabled". After that, you need to press F10 for the changes to take effect.
One of the suggested methods should help in solving audio problems. If the audio does not play in separate files, then the reason is the lack of the required codecs. If there is no sound in the game or application, but the system sounds work, you need to check the settings for specific software or reinstall it. In this case, the hardware or OS is not related to the malfunction.
If you don't have sound on your Windows 7 computer, try my recommendations. The first thing we look at is the tray icon, which should not have a ban. Also make sure that the upward volume slider does not increase the volume of the speakers. Next, check if your speakers are set as the default device.
To do this, go to the control panel where you want to find the sound. Run it and set the required device as default hardware. Then save the settings with the "OK" button. After that, does the sound still not work on your computer? Then you need to check the installed codecs. Although the operating system installs them, download just in case and install K-Lite. I will now list which formats you need codecs for. These are mpeg, avi, mov, ts, mkv and flv. Is the problem still not resolved? Then check if the drivers are installed. Try reinstalling them. Because of them, the sound on the computer often does not work.
Also, your sound may disappear due to various conflicts between the sound driver and software on other devices. There are times when you connect to the Internet. This happens just by a network adapter with a sound card. You can check for such disagreements through the device manager. An exclamation mark icon on a particular device will alert you to such problems. In this case, update the software for each specific device.
There are times when the integrated motherboard refuses to work. If the sound on your computer does not work under such circumstances, go to the BIOS settings and check if you have a sound card enabled there. This is done as follows. When the computer boots up, press the Divide or F2 key. Go to the integrated devices (or advanced) tab. Search the list of equipment for the name of your card. Found it, great. If it says it is disabled next to it, press the enter button and then enable it. Next, you need to exit the BIOS with all settings saved. To do this, press Ф10 and select Yes. After that, your machine will reboot.
What else can be the reason that the sound on your computer does not work? When you have completed all the above steps, and you have not received the desired result, you need to check the sound card, as well as your speakers for possible inoperability. Both, it will be impossible to test without the necessary equipment. Therefore, to test the speakers, try connecting them to another computer or laptop, and connect other speakers to your device. If no shifts have occurred, take both to the service, where they will probably find out everything and, if possible, eliminate the existing problems with your equipment.
That, in principle, are all the reasons due to which the sound on the computer does not work for many users. By the method of elimination, you can find your own. Check your computer and settings from the first step until you get to the bottom of the true cause of the hardware failure. Also see if the speakers are connected to the audio card and plugged into the mains.
You come home, turn on your computer or laptop, and while it is loading, make plans: now I will turn on the music, sit on the Internet for half an hour, and then watch a new movie. Launch the media player with your favorite tracks and ... find that there is no sound on the computer.
What the heck? Yesterday everything was fine, everything worked! It seems that nothing was installed and nothing was "chemically", but there is still no sound in the speakers (or headphones).
Unfortunately, this happens quite often. On any computers and laptops. And on any operating system - Windows 7, 8, 8.1, 10 or XP. Nobody is immune from this.
However, you do not need to blindly search for the cause of the malfunction. After all, below are the most common problems due to which sound on a PC may disappear. And 10 ways to solve them.
If the sound on your computer does not work, then first of all you need to check the speakers. Perhaps you connected them incorrectly. There are 6 outputs on the back of the PC. You need green (it is he who is intended for speakers / headphones) and pink (if there is a microphone).
You may have confused the outputs.
The front panel of the system unit may also have headphone and microphone jacks. And in some cases they are not color coded. Therefore, try to connect the connectors in a different order.
Also, there are times when the inputs wear out. In this situation, you need to correct them, i.e. disconnect and reconnect. This can help. At the same time, it will not be superfluous to clean the PC from dust.
Also check if the speakers are on. The fact that they are working is indicated by a small LED.
Check your sound settings
The next thing to do is check your sound settings. Maybe it is disabled or screwed to a minimum.
Let's consider the setting using the example of Windows 7 (in Windows 8 and 10 it is done in the same way):
1. Click Start - Control Panel - Hardware and Sound. 
2. Select the item "Sound". 
3. All audio devices are displayed here. Select a specific device and click "Properties". 
4. In the new window, you need to look at 2 things: 
- whether the device is detected - if not, then you need to install the drivers
- whether it is on - if not, then turn it on (select the appropriate item).
5. In the same window, go to another tab - "Levels". Look at the volume scale - it is recommended to set it at 90-100% (at least for a while, until the sound appears, and then adjust it for yourself). 
6. Next, in the same window, go to the next tab - "Additional". When you press the "Test" button, music will play for about 5 seconds. 
If you do not hear anything, then save the settings and go to the 7th point.
7. Go to "Hardware and Sounds" again and select "Adjust volume". 
Here you can see if the sound is screwed to the minimum. 
8. You can also check your audio settings. Click on the speaker icon in the lower right corner (where the time is displayed) and check the volume level.
Sound driver missing
The next step is to check the sound driver on the PC. Quite often, problems arise precisely because of him. Yes, and you could already find this malfunction in the second paragraph (when you looked to see if the audio device was detected in Windows).
To check for the driver, you need to go to "Hardware and Sound" again and select "Device Manager".
In a new window, open the item "Sound devices". If the sound card is connected correctly, it will be listed.
If it is displayed, but a yellow or red sign is lit opposite it, it means that the driver is either not working correctly or is not installed at all. There are two ways to install the driver:
- from the disk that comes with the PC (you need a disk for the motherboard);
- from the Internet (if there is no disk or you have a laptop).
If you do not know what kind of sound card you have, you can use the AIDA64 program - it will show not only its model, but also tell you the address from where to download the driver.
If there is a sound card, but Windows does not see it for unknown reasons, then it is difficult to say what the problem is. The device may be poorly connected. Or completely faulty. It can also be related to the hardware of the PC.
Video / audio codecs missing
If there is sound when loading Windows, but there is no sound when you turn on any video file, then the reason lies in the video player, codecs or file (it may be damaged).
In the first case, you can put another video player. For example, today KMPlayer is one of the most popular. Plus it already has built-in codecs for playing video files.
If the problem is with the codecs, then you need to remove them and install new ones. It is recommended to use a set of codecs called K-Lite Codec Pack. It has all the codecs you need and even a built-in video player that can open almost any file.
Incorrect BIOS settings
This kind of problem is extremely rare, since usually the sound card is always on. But if you like to overclock your computer or for other reasons change the settings in the BIOS, then you should check them. And restore sound on the computer (if necessary).
To do this, you need and find the line that contains the word "Integrated".
If everything is in order, then exit the BIOS (if you changed the settings, do not forget to save them).
Virus software and viruses
Another reason is virus software and viruses. Today there are so many of them that it is difficult even to say what "surprises" they can present.
The best option would be to scan your computer or laptop with any antivirus (do not forget to update the databases before that). It could be Kaspersky, Dr. Web, etc. For example, DrWeb CureIt is considered a good option (you don't need to install it).
Restoring sound on a computer
If you still can't hear sound from your PC or laptop, here are some more tips:
- If literally yesterday everything was fine, but today the sound disappeared, it is possible that new drivers were installed or some programs that caused this problem. In such cases, you can try.
- If there are more speakers, connect them to your PC and reinstall the drivers (remembering to remove the old ones).
- If all else fails, you can go for broke and (do not forget to save all important files before this, because they will be deleted). After installation, immediately install the sound drivers. If the sound appears - then watch what software you are installing.
- Another option is to connect headphones instead of speakers. Or vice versa.
- And the very last option is to contact the service center for help.
However, one of these methods should help. Therefore, if you have lost sound, try different options - it is quite possible that you will be able to solve this problem on your own. In 95% of cases, this problem is solved on their own.
The presence of sound on the computer is taken for granted, but sometimes, due to various problems, it disappears. In this case, the soundtrack is absent not only during the playback of media files, but also during system events. The reasons for this kind of malfunction can be different and be of both hardware and software nature. For novice users, the problem may seem serious, but you shouldn't rush to contact the service center. To figure out why the sound on the computer does not work, in 80% of cases it is possible without resorting to the help of specialists.
Before starting diagnostics
So what if there is no sound on the computer? Try to remember all the actions that you have performed on your PC recently. Maybe they installed some kind of drivers or programs for working with sound, maybe they changed the settings, applied tweaks, were there any system failures, virus attacks, and the like before that. If so, at least you will know where to start looking for the source of the problem.
Acoustic equipment problems
If the sound on the computer has disappeared for no apparent reason, you need to start with diagnosing the acoustic equipment. Check if the speaker plugs are firmly seated in the jacks, if there are any kinks in the cable that have damaged it. In general, it's best to connect your speakers to another PC. If they work, then everything is in order with them, and the source of the problem must be looked for elsewhere.
At the same time, check whether the speakers themselves are turned on, it often happens that the user accidentally turns them off, for example, wiping dust from the surface, and forgets about it. And, of course, the speakers must be properly connected. The speakers are connected to the green connector (audio output), and the microphone is pink. The colors of the plug and the connector must also match.
Basic audio settings fail
After making sure that everything is in order with the speakers, you can start checking the basic audio settings. Their failure is one of the most common reasons why no sound is played on the computer. Pay attention to the appearance of the volume icon in the tray. If it is not crossed out, it looks normal, but there is no sound, there may be some temporary problem in the system. Restart your computer and check if there is sound. If it does not appear or the icon is generally marked with an icon with a red cross, do the following.
Click on the RMB icon and select the "Playback Devices" option.
The "Sound" window will open, on the "Playback" tab of which you will have a list of available audio devices. If it is empty or there is no “Speakers” device in it, open the RMB context menu and check the boxes for the options responsible for showing disconnected and disconnected devices.
If the device is disconnected, turn it on, and if it is marked as disconnected, again check that the PC speakers are connected correctly.
Note: you can also use a disabled device through the properties window. The speakers should be set as the default audio device.
Crash and stop the audio system service
The sound on a Windows 7/10 computer often does not work because the system service responsible for it is stopped. It's not hard to check this. Team services.msc open the service management snap-in, find the entry in the list Windows Audio and click on it twice. Pay attention to the state of the service. It should have the status "Running" and the startup type "Automatic".
If the settings differ from those shown, change them. If they are correct, restart the service by first clicking the Stop button and then Start.
Driver problems
For audio devices to work properly with the system, the appropriate drivers must be installed in it. The drivers for the audio card are missing or damaged - as a result, the sound on the computer does not work. What to do in this case and how to check if everything is normal with the drivers? And there is nothing complicated here either. Open Device Manager from the Start menu and expand the contents of the item "Sound, game and video devices". If an item with “Audio” in its name is marked with a yellow or red icon, then you most likely have a software problem with that device.
This sometimes happens after incorrectly updating drivers or accidentally deleting them. Double click to open the device properties, switch to the "Driver" tab and try to roll back or, on the contrary, update the driver.
It also happens that in the Device Manager you will not have the specified item at all, instead there will be some unknown device. In this case, it makes sense to use some third-party program to find drivers, for example, DriverPack Solution.
Audio card disabled in BIOS
The reason that there is no sound on the computer can be lost BIOS settings, namely, disabling the audio card. Depending on the BIOS version, the list of integrated devices must be searched either in Advanced - Onboard Device Configuration, or in the section Integrated peripherals... The setting can be called HD Audio Controller, High Definition Audio or otherwise, but its name must contain the word "Audio", and the value is set to Enabled.
Only system events are accompanied by sound
If sound does not work on Windows 7/10 only when playing audio and video, but the problem does not affect system events, then, probably, the matter is in the incorrect operation of third-party software (players) or codecs, although damage to the multimedia files themselves cannot be ruled out ... Uninstall and reinstall audio and video players, at the same time it is also recommended to install the codec pack K-Lite Codec Packthat supports most multimedia formats.
Viruses, damage to system files
Virus activity and system file corruption due to crashes can also cause audio problems. After scanning for viruses as part of the diagnosis, you should check the integrity of the system files. To do this, in the command line run as administrator, you must run the command sfc / scannow and wait for the result.
Sound disappeared after updating, changing settings or installing programs
The reason that there is no sound in Windows 7/10 may well be low-quality third-party applications for adjusting audio settings, tampering with the registry, and other similar actions. In this case, the installed software must be removed, and then rolled back to. If you encounter problems with sound that arose immediately after installing cumulative updates, you need to remove them, and when upgrading to a new release, roll back to the old version of the system.
The audio card is out of order
Broken audio card is not a common reason for the lack of sound, but it does not hurt to exclude it. The failure of a sound card may be indicated by the absence of a corresponding entry in the Device Manager, as well as the absence of playback devices in the "Sound" window called from the system tray. Alternatively, you can boot from a LiveCD with a Linux-based portable OS and check if the audio files on the disc play and sound works at all.
So, we tried to cover the main points of why there is often no sound on a Windows 7/10 computer and how to fix it. The examples provided, however, are not all inclusive. It can never be ruled out that there are other problems on the PC, for example, breakdowns of individual components of the motherboard, damaged wires, etc. If you suspect problems with the audio card itself, it is better to seek help from specialists, after cleaning the computer from dust and making sure that everything is in order with the slots.
