Why there is no sound on the computer - step-by-step sound restoration. Physical breakdown of audio equipment
Quite often, users are faced with the loss of sound on a computer with the Windows 7 operating system. There are many reasons for this. Some are quite simple. And sometimes it takes several days to find a problem. This short review is dedicated to how to find and fix the breakdown.
Non-working speakers
Let's consider possible options breakdowns:
These measures are basic, but you shouldn’t forget about them. If the check didn't yield anything, then it's time to move on.
Hardware audio settings
After obvious faults have been checked, it is worth paying attention to software settings sound. It is quite possible that the sound in Windows is turned down or completely turned off. If it is reduced so much that it is barely audible, then the user will most likely assume that the computer itself has broken down.
It’s best to see visually how the sound is adjusted at Windows example 7, on Windows 8 and 10 the principle of operation is the same:
Let's look at the functions of the window that opens in more detail:
If you are unable to reproduce the test sound, you should check whether the sound is turned down to minimum value or disabled altogether:
Check Device Manager
If there is no sound on the computer under Windows control 7, as well as operating systems Windows 10 and other versions, you should check the status of the mini-programs (drivers) for the sound card. Most likely, they need to be updated or they are not there at all.
You can check the status of the equipment and its drivers in “ Device Manager", which is easy to find in Control panels on the " System». 
Systematically displays all devices that are present on a computer or laptop, as well as the status of their drivers. If a yellow triangle is lit nearby, you should pay attention to it first. This means that the sound card is not working at all or is not working correctly. In our case, we are interested in the item “ Sound, video and gaming devices». 
If a problem is identified due to which the sound does not work, you need to download and install a driver that is compatible with this PC. You can keep your computer up to date using special utilities for automatic updating and searching current version drivers for any hardware on a PC or laptop. For example, the program Everest will determine the sound card model, check all drivers for relevance and tell you where to find them necessary drivers for sound on Windows 7.
When you monitor the current state of your computer and carry out regular updates, you may encounter the problem of no sound during the next automatic driver update. The source of the problem may be updated driver. "" will help restore the working situation. On the " Driver" his sound card you must click the Rollback button. 
If the problem goes away, it's better to disable automatic update drivers for this device.
Updating drivers in Windows 10
The algorithm of actions consists of the following steps:
No audio/video codecs
If there is sound in the browsers, but there is no sound when you start the video on the PC, then you should look for the problem either in the media player itself or in the audio codecs.
To constantly watch videos, it is recommended to use KMR player. He has already proven himself and is showing good results. The creators of the program have provided a lot of different codecs for video playback. And, as a rule, most films are successfully reproduced in this program.
The problem with codecs can be radically solved using the package K-Lite Codec Pack . It can solve the missing sound problem. He has full set current codecs that open almost all popular formats, both video and audio files.
Viruses and adware
Problems with sound on Windows 7 may mean that a virus has appeared in the system. There are many types of viruses and they can negatively affect the operating system.
How to behave if the sound on your computer disappears and you suspect a virus:
- Take a close look at how your computer works as a whole. If it begins to freeze frequently or suddenly slow down, then most likely the PC has been subjected to virus attack. If the installed antivirus program failed and missed the virus attack, then it is best to check the system third-party antivirus with current virus databases. For example, you can use the utility Dr.Web CureIt. This healing utility successfully cures an infected system.
- You can try checking your computer using Live CD(emergency boot disk). You can use it to download a lightweight version operating system with a ready-made antivirus. If you boot the restored system from Live CD sound appears, then most likely there is a malfunction in Windows 10 itself. Most often, you will have to reinstall it or perform a system restore using restore points, if this mode was enabled and restore points were created.
Checking the BIOS settings
If your computer or laptop has a built-in sound card and there is no sound even in headphones, then you can look BIOS.
This is an extreme measure - AC97 is enabled by default in the factory settings. If the settings are incorrect, the sound device in the Windows operating system will not work.
Each computer logs into the BIOS differently. For example, for ACER computers, before booting the system, you must press and hold the Del key. In general, before loading the operating system, you must indicate how to enter the BIOS.
After pressing the Del key, the following dialog box will open, in which you need to select the item “ BIOS Setup».
In the window that opens, you need to find an inscription like AC 97 Audio, use the arrows on the keyboard to highlight this inscription and click on the Enter key. A dialog box will appear to select which function to activate HD Audio or AC97. We are interested in the AC97 “Auto” inscription. Confirm your choice and use the ESC key to exit this section. Exit the BIOS, saving the settings.
If you can’t get the sound back after changing the BIOS settings, then the last option is to replace or send the sound card for repair.
Laptop owners often encounter the problem of no sound in the Windows system. Because of frequent overheating sound chipset, the computer begins to malfunction. And all the rest of the electronic stuff is simply choked with dust, unless, of course, you do regular cleaning, and gradually fails, which can also lead to loss of sound on the laptop.
Conclusion
Of course, these are not all the reasons why there may be no sound, but the main, most common versions are revealed.
So, we told you how to restore sound in Windows 10, 7 and 8. And our main advice- don’t despair, but try all the options step by step.
Video on the topic
It's hard to imagine a funnier situation than watching the next Comedy club episode on a PC without sound. At the same time, this kind computer problem is far from uncommon in user practice. Big to that An example is the irrepressible popularity of questions about how to turn on sound on a computer. Yes, the “unauthorized boycott” declared 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, you, dear reader, are in luck again! Because in just a few minutes you will be able to “untie your tongue” on almost any Windows operating system. Well, let's not waste precious time - let's turn to the experience of professionals.
Diagnosis of computer “dumbness”
The answer to the question of how to restore sound on a computer must be sought in two directions. The fact is that most often the system “loses its voice” due to software glitches. However, the sound may disappear as a result of failure of any hardware component. For example, an integrated audio chip. To understand what exactly is the cause of “silence”, you need to resort to step by step plan actions. Only after a thorough practical analysis will you be firmly sure what type of your sound fault: hardware or software. However, let's not talk about the bad - everything should be resolved without the intervention of a specialist.
Step No. 1. Basic check
Tell me how to turn on the sound on a computer if the speakers are not working or are simply not connected? Of course, no way! Exclusively 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 does the jack used correspond to the destination device?
- Location of the plug if the speakers are powered from an electrical outlet.
- What position is the volume control in? Perhaps it is twisted to zero.
- Is one of the connecting cords damaged?
Often it is precisely such “platitudes” that push a person to take wrong actions. Therefore, be careful. Connect known-good speakers. Perhaps all your fears are in vain!
Step No. 2. Detect “secret” signs
If there is no sound on your computer, pay attention to the speaker icon located in the system tray. It may be crossed out, which means the playback device is deactivated. Move the slider up. If everything remains unchanged, move on 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 special services, one of which is responsible for playing audio material. Full customization sound on the computer without participation Windows Audio simply impossible. Therefore, it is necessary to check the current status of this service.
- Using the Win+R hotkey combination, bring up the “Run” menu.
- In the window that opens, enter the command services.msc. After confirming with the “OK” button, you will be redirected to a special “Services” section.
- Find in the presented Windows list Audio.
In order for sound to be played and audio settings to be correctly recognized by the system, you must make sure that the service is active. That is, in the “Status” column the “Running” parameter is indicated, and in the “Startup Type” column the value is set to “Automatic”. You can make the necessary changes using the same right mouse button, placing the cursor on the item that requires appropriate editing.
Step No. 4. Driver that may crash
A crossed out speaker in the tray may also indicate the incapacity of the special audio chip manager program code. In other words, the sound on the computer disappears when the driver becomes inoperative.
- Open the Start menu.
- Then go to the “System” section.
- On the left side of the window, select “Device Manager”.
It will not be difficult for you to discover the “culprit” of a problematic situation. In the list presented, a non-working device will be marked with an exclamation or prohibition mark. Update sound driver using a service disk (software for the motherboard included in the kit). If you don’t have one, you need to go to the manufacturer’s official website and in the “Support” section download the corresponding modification of your PC software tool. It is worth noting that before installing the latest version of the sound driver, you must remove the old device management component.
Standard Windows functionality
When all your attempts practical actions answering the question of how to turn on sound on a computer did not bring a fruitful result, it makes sense to use the incredibly convenient “Fault Diagnostics” option. However, this functionality is only available in more later versions operating room Windows systems. To start it this tool corrections 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 about the result of the work performed. It is likely that such a sound setting on a computer will become an effective salvation for a seemingly “deaf” situation.
Step #5: Settings
If you are sure that the driver is installed correctly, and the service window sound device“Properties” displays the current status “Working normally”, then the solution to the question “how to turn on sound on a computer” should be found in to the following algorithm 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. From the context menu, select “Properties”.
- While on the “General” tab, pay attention to the “Device Usage” item below. More precisely, the value in the checkbox. Apply the On option.
In the case when the mentioned list contains several installed devices playback, one of them should be set to “Default”.
Step #6: Audio Controller
As a rule, most manufactured motherboards implement advanced sound scheme. That is, the integrated audio chip can be controlled through a special installed driver. Let's look at an example where the sound settings on a computer are done using the Realtek HD manager.
- Click on the speaker icon (darker in color and slightly large sizes, how standard Windows controller volume).
- In the dispatcher working window that opens, you need to activate the icon in the form of a wrench (bottom part of the interface, on the right).
- In the case when no sound is played, it is necessary to change the diagram from one value to another (meaning “Front panel of 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 No. 7. Unclear media format
There are often cases when sound playback on a computer is impossible due to a missing audio codec. This problem can be easily corrected.
- Enter in search bar browser K-Lite Codec Pack.
- Then select the official source of the product from the list provided.
- Download and install the necessary software.
Usually this action gives the PC “omnivorous” multimedia capabilities. Rest assured: your computer will not be an exception to the rule.
Step No. 8. Software incidents
It happens that after installing certain software the sound disappears, and after uninstalling conflict program reappears. Some media players play a limited number of audio and video formats. This is the only reason why unlucky users often begin to panic. Therefore, before installing any program for viewing and playing multimedia content, you should refer to reviews of the product and a review of its tactical and technical capabilities.
Step No. 9. Look for the reason in the BIOS
As you know, the BIOS firmware manages and controls the operation of all hardware computing device. So installing sound on your computer may be mission impossible, when in BIOS for some unknown reason Audio functionality is disabled. However, knowing the main rule when working with basic system: “Do not touch or change unknown values”, you will successfully complete the task.
To check whether the audio function is enabled in the BIOS, you need to do the following:
- Enter your PC's Bios.
- Depending on the version of the BSVV, the location of the sound “switch” may vary. However, the name "AUDIO" and the value "Enabled/Disabled", or "On", are unchanged.
- Find the tab with the Onboard Device Configuration option, or High Definition Audio doesn't seem to be difficult. The main thing is to understand the seriousness of the enterprise and not make rash changes to the firmware. Since this is fraught...
Step #10: System Restore
If, after all the manipulations, the question of how to install sound on your computer remains unresolved, then it would be prudent to use the method presented below.
- Go to the Start menu.
- Enter “recovery” in the search bar.
- Once the section you are looking for is displayed at the top of the service window, press Enter.
- Select the required backup copy and confirm your choice with the appropriate key.
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 lost recordings in system registry. After all, very often the user, as a result of erroneous actions (usually in pursuit of free space on the hard drive), deletes important OS data. Ultimately, the inevitable happens - Windows loses full functionality. However, the would-be user does not always have the opportunity to roll back the system to its original state. By the way, the reason for everything is the same well-known reason - saving space on the HDD, that is backup copies There is simply no OS, since System Restore is purposefully disabled. Nevertheless, even in such a situation there is a way out.
- Press simultaneously Win keys and R.
- In the Run menu, enter cmd.exe
- · In the command window, type sfc /scannow.
- Press Enter.
Damaged data will be recovered from backup storage. It is likely that after rebooting the OS you will hear the audio greeting again.
Step No. 12. Viral infection
Malicious code not only steals and destroys user data. A virus program that has infiltrated the operating system environment may also be the reason why the sound on the computer is lost. In order to identify a pest, it is necessary special software. Often traditionally used for protection antivirus program not quite enough. However, today there are no effective exterminators on the Internet. malicious code plenty. Therefore, you should not have any particular difficulties in the process of finding the necessary software tool.
- So that your PC never experiences sound problems, periodically check on the official website of your manufacturer (motherboard manufacturer) to see if more latest versions drivers.
- When connecting audio playback devices to the PC system connectors, it would be a good idea to understand in more detail the correctness of the connection diagram involved.
- Often motherboards have special contact pads that can be connected with special jumpers in order to reassign the audio output. Therefore, it is worth turning to the documentation of the motherboard and studying the problematic issue in more detail.
- If all methods fail to meet your expectations (which is unlikely to happen), seek specialized help.
How to connect sound on a computer? As you can imagine, this is an incredibly large question. However, today you have learned a lot of information about what needs to be done to “talk” your electronic friend, and what should be feared during its operation. All the best to you and pleasant sound experiences!
Installing an audio device is not at all difficult. Just connect its outputs to your computer and you can get to work. But when there is no sound, then curses are followed by search queries. After all, there are dozens of reasons for the lack of sound that baffle even an experienced user.
Lack of sound is rarely due to equipment malfunction. In most situations it is missing due to a poorly configured system. To resolve this issue, make sure your audio settings are correct.- First of all, check the status of the sound driver. To do this, in Windows 7, open:
- Control Panel>Devices and Printers. From the list of equipment, select the one you need and click on it. Then open the Driver tab and click Update. Specify the path to the CD. Right-click on “My Computer”, then “Device Manager”. In the list that appears, find required device
old part
. But don't do this without trying every possible option.
If none of the options solved your problem, then we recommend calling a specialist to your home. If you wish, describe your situation on one of the computer forums. Such searches will take more time, but there is a chance that a similar problem has already been solved before you.
Follow the steps listed in order. The first one doesn’t help - move on to the second one and so on.
If the sound is gone on a Windows computer
1. If there is no sound only from headphones or external speakers, make sure they are properly connected to the computer and power source. If your audio device has a switch or volume control, check it.
2. If there is no sound from the built-in speakers, make sure that headphones and other audio devices are disconnected from the computer ports.
3. Check the status of the audio device. To do this, right-click on the volume icon and select “Playback Devices”. Make sure the device you want is enabled and the default. If it is not, change its status using the surrounding buttons. If you see a list of several devices and don’t know which one to choose, turn them on one by one and check the sound.
4. Check the audio levels in the system mixer. Right-click on the volume icon and select “Open Volume Mixer.” Move the sliders and check for sound. 5. Restart your computer. This will help if the sound is lost due to a simple software glitch. 6. Check the Windows Audio service.

double click . Make sure its startup type is set to automatic. If this is not the case, change the value to “Automatic”, click OK and restart your computer., or on the manufacturer's website. If you don’t want to search and install the driver manually, you can use it, which will do everything for you.
8. Install the latest available updates for your Windows versions. This can be done in the Center Windows updates", which can be easily found by searching the system for the query "updates". If it doesn't help, try it.
9. If none of these methods work, you can take the computer to a service center.
If the sound is missing on a computer with macOS
1. If you only have no sound from your headphones or external speakers, make sure they are properly connected to your Mac and the power source. If your audio device has a switch or volume control, check it.
If possible, connect headphones or speakers to another computer and test them. If they don't work, you can take the accessory to a service center.
2. If there's no sound from the built-in speakers, make sure your headphones and other audio devices are disconnected from your Mac's ports.
3. Turn off your computer and unplug the power cord for 30 seconds, then plug it back in. After 5-10 seconds, start your Mac again and check the sound.
4. Check your audio settings. To do this, open apple menu and go to the section " System Settings» → “Sound”.

Wanting to view family video archives stored on your PC hard drive, you suddenly discover that something is missing sound accompaniment. If you take into account that your user knowledge is initial, you can imagine how difficult it is similar situation for you. Of course, you have no idea how to make sound on a computer, and everyday experience only tells you what might correct the situation. However, this was not the case. Well, let's look at the main ways to restore sound. After all, in in this case silence is far from golden!
Where to look for the reason?
Perhaps careless manipulation of files led to the removal of the sound driver. It is likely that the voice acting manager machine code“flew off” spontaneously. The computer hardware, in particular, could very well fail. Recently installed program may also turn out to be the “initiator of the game of silence.” Finally, the culprit of computer “dumbness” may well be malicious virus. And that's not all possible reasons, due to which many users have the question “how to make sound on a computer.” From this point on, we will consider the situation in more detail and with the ensuing conclusions.
Banal inattention
In the service area, the sound level icon “hangs” on the right. If the displayed “speaker” frames a prohibitory sign, you need to move the slider up. Again, the crossing out symbol in the form of an X means a malfunction of the sound device, that is, the driver may have crashed. Make sure they are enabled. It is worth noting that the silence of the speakers during video playback is often expressed by the absence of multimedia codecs. In this case, it is recommended to install comprehensive package"K-Lite Codec Pack". The installation process will only require clicking the “Next” button several times. However, there are plenty of opportunities and options on how to make sound on a computer.
Device Manager - beacon of faults
You need to make sure that the sound driver is recognized by the system as a correctly working software component.
- Go to the Start menu and go to Control Panel.
- Open "System" and activate the "Device Manager" item.
- In the window that opens, none of the items, and in particular “Sound…”, should be marked with a red cross or exclamation mark.
- On the corresponding speaker icon, right-click and click on “Properties”.
- Pay attention to the window diagnosing the device status. Typically, the operating mode is indicated by the line “...working normally.”
- Otherwise, you need to reinstall the sound driver, first removing the faulty component.
If the above method did not bring an effective answer to the question “how to restore sound on a computer”, proceed to the next stage of troubleshooting.
Visual inspection of the computer
So, first of all, you need to check technical condition speakers, the position of the cords relative to the corresponding audio input sockets, and also make sure that the sound card itself is working.
- Mobile phones, as well as televisions and DVD players, are equipped with a 3.5 mm jack. It will not be difficult for the user to connect the speakers to any multimedia device for the purpose of testing for functionality.
- Connecting wires and plug terminals can also become damaged due to internal breaks and mix-ups. It is recommended to use ordinary headphones in order to compare test results.
- If your PC does not have an integrated sound card, make sure that the “melodic” module installed in the PCI is installed correctly and the device is properly positioned in the slot.
- The ideal option is to replace a sound card that is known to work.
How to make sound on a computer: BIOS settings
If your motherboard has an integrated one, it’s worth going into the BIOS and viewing the audio device settings.
- After turning on or rebooting, press the "del" or "F2" key several times.
- Depending on the type of BIOS you have, audio device parameters may be displayed in different tabs. However, it is most likely that you will find the item you are looking for in the "Advanced" menu.
- It is likely that the device responsible for the sound has the “disabled” parameter. Changes can be achieved by pressing the “enter” key, set the value to “enabled”. Perhaps in this way you will receive the long-awaited answer to the question of how to restore sound on your computer.
- Save the revised settings and restart your computer.
If you managed to “talk the numb electronics,” it makes sense to programmatically improve the sound device.
Review of the most acceptable software solutions: "Razer Surround"
The presented aggregator will allow you to improve the sound on your computer. It is worth noting that the software is designed for gaming applications. However, this inconvenience does not in any way affect its use in multifaceted applications.
- Install the downloaded software on your PC and launch it.
- Complete a short registration and enjoy an incredibly effective sound management tool.
"Volume"
The name of the program speaks for itself. The installed application allows you to qualitatively improve the comfort of managing playback parameters. One of the advantages of the software can be considered the implemented ability to assign “hot” keys. In other words, efficient setup sound on the computer - the "Volume" program.
Of course, the software mentioned above is absolutely free. The only limitation (“Razer Surround”) may be the lack of computer hardware capabilities to reproduce multi-channel 7.1 audio.
Finally
Connecting sound on a computer, in general, is not a difficult task. However, given the existence of incredibly complex audio circuits, the user may encounter some difficulties. However, if you read this article, most likely, it will not be difficult for you to find a solution to all “incomprehensible” problems, including connecting various equipment. Sweet realizations to you!
