Hello friends! In this article you will learn why the output audio device is not installed what to do with this problem, how to solve, etc. I have often had to deal with the situation when the sound disappeared on the PC. In this regard, on operating system Windows vista and xp quite often there was a message that the output audio device was not found, in other words, the system simply did not see the speakers or headphones, but they were. Without thinking twice, I began to look for a solution and solved the problem. Want to know how? Read the article further.
The most frequent reasons for the lack of sound
- First thing make sure in good condition speakers or headphones. Check the wires for integrity, correct connection (is the correct socket used for connection).
- The lack of sound in the online game may be due to blocking the corresponding network screen packets.
- Wrong work sound drivers or other software.
With the first two points it is understood, for their solution, check the audio device for operability or carry out the setting of the network screen in an online game. But installing or reinstalling the driver requires attention.
Install or reinstall the sound driver
The driver can be installed from the official licensed disc that came with your computer or you can update it via the Internet.
And you can do it like this:
Since the device does not work correctly, the system will most likely mark it in yellow with an exclamation point. If you did not find such in the list, then connect the device again and check for serviceability.
Select the tab “ Driver"And click on the" Refresh» 
If you could not do the operation In automatic mode, use the "Roll Back" function. The last action will return the working version of the driver.
And so, all the points are made, but the problem is still not solved, and the PC asks to install an audio device. Then you need to restore the system through the button " Start". Further " All programs > Standard > Service". In this section, select the starting point when the speakers and headphones worked fine and start the system restore. 
If this does not help, then things are really bad, most likely, the problem lies even deeper than I thought, and damaged system filesaffected by viruses.
Both music lovers and film fans, and even those PC users who are just used to the background sounds of their favorite Windows 7, periodically face problems if not in sound, then in connecting audio devices. It seems to be working a month or two or a year, and at least some hint of a possible malfunction. And then a clap at one point, your favorite operating system presents a surprise in the form of a message that the output audio device is not installed on the computer. Neither answer you, nor hello to you. The sound faded like a rabbit in a magician's hat.
Of course, the easiest way out is to say goodbye to Windows 7. But is it worth calling this solution the right one? By no means. In fact, troubleshooting an audio device in Windows 7 is easy. True, it is extremely important to correctly identify the cause of the problem. How to do it? Let's see!
Causes of audio problems
On computers running Windows 7, a message about problems with the output audio device may appear for several reasons:
Thus, the problem with the lack of sound in Windows 7, accompanied by the appearance on the desktop of the error "output audio device on the computer is not installed," may be due to various factors. It is from them that we will have to dance in order to eliminate such a problem.
Method number 1: Check the sound device
The first thing to start debugging sound in Windows 7 is to check the sound device connected to the computer. First you need to make sure that the speakers / headphones / microphone are connected to the PC correctly. In this case, several faults can be detected:
Detecting these problems is easy enough; all you have to do is look closely at the details of connecting to the PC of the output audio device. Note that in most cases, after re-connecting the device correctly, the problem is solved by itself.
However, if the error was not eliminated by such actions, in order to exclude other possible problems with sound on a computer with Windows 7, you need to check the equipment by connecting it to another laptop or PC. There are two scenarios:
- a message with an error on another computer appears again: we solve the problem by replacing the sound device, because the reason lies precisely in it;
- problem is fixed: debug using the methods described below.
Method number 2: Computer analysis for viruses
It's no secret that after a virus attack, more than half of all computer malfunctions occur, including those related to providing sound effects. In this case, if Windows 7 after another “hike” on the Internet or installing questionable software did not recognize the output audio device connected to the computer, it is worth trying to check the system for viruses. It’s very likely that a Trojan was hiding somewhere, slowly killing your favorite operating system from the inside.
Anyway, if it is established that the cause of the malfunction is precisely this, after performing a complete windows checks 7 for viruses and restarting the computer, the problem should be fixed. Otherwise you have to move on.
Method number 3: Disable antivirus software
Quite often, in Windows 7, the connection of the computer with the output audio device may also not be established as a result of blocking this equipment by an antivirus program. From a theoretical point of view, everything is simple: the antivirus simply did not like the software filling of the sound device. How to be?
In this case, you can go to the following trick: before connecting an audio device, temporarily disable the antivirus program. If after a sound device is working, and a sound appears on the PC, the answer will be asked by itself: the antivirus is to blame for the error. It is clear that the solution will be either reconfiguration of the antivirus program or its removal.
Another point that fits this case is that the anti-virus program temporarily blocks individual components of the software. How can this be fixed? In favor of this reason, in particular, the fact will be expressed that the sound periodically disappears during a particular game or work in the program. The solution, in fact, will be the same as in the previous case: disabling / reconfiguring / deleting antivirus.
Method 4: Debug with the Troubleshoot Wizard
In Windows 7, you can also use the integrated troubleshooting wizard to troubleshoot the sound device. It is quite simple to start it: right-click on the “Sound” icon displayed on the taskbar, and in the proposed menu, select the “Troubleshoot audio problems” option:
As a result, the Troubleshooting Wizard will start automatically, providing verification of the computer and debugging the malfunctioning of the output audio device:
If after the performed actions the sound did not appear, you can select in the appeared window the tab “View extra options". However, if, as a result of these settings, the connection to the audio device is still not established, you will have to proceed to the next way to fix the problem.
Method number 5: Reinstalling drivers
It is also possible to solve the problem with sound on the computer by reinstalling (updating) the audio device driver. In this case, click "Start", enter the "Control Panel" and select the "Device Manager" item in the opened menu:
In the opened window, click on the “Sound, video and gaming devices” section, then find the sound device in the list that appears, right-click on it and select “Update drivers” in the new menu:
As a result, Windows 7 will offer to search for drivers. The easiest way, of course, is to choose automatic update:
As a result, if the sound device drivers are available for download, after performing the search, the update will be installed automatically.
If this does not happen, you can try to download them from the site of the PC manufacturer or the supplier of audio equipment (for example, Realtek or Creative Audigy). After this is done, we return to the device manager, click "Driver Update", select "Run driver search ...", and then - "Select driver from the list ...":
After this, click “Install from disk”, register access to the file with the drivers and click “Next”:
As a result, the update will be installed automatically.
Method number 6: System Restore
If the problem could not be solved by any of the methods proposed above, the only thing that remains is -. You can do it like this:
In principle, after restoring the system, the error with the definition of the output audio device on the computer with Windows 7 should disappear. As you can see, everything is quite simple!
In order for your computer to have the ability to play sound, everything must be properly connected and configured. It is not at all difficult to do. And in this article we will show how. If you follow our recommendations, you will never see the error message “audio output device not installed”.
Do not immediately worry that a hardware error has occurred, and your sound devices not installed. Perhaps it is a software failure. Let's do everything in order.
The reasons for the lack of sound
As we have already noted, for the sound devices to work correctly, they must be properly connected. We will look at this process in more detail in the next chapter. What can be noted here - we must check the following components:
- Headphones
- Columns
- Sound card
Including it is necessary to ensure their performance.
If there is no sound reproduction when working with a specific software package, or, say, a computer game, the first thing to do is to understand their local settings. It is difficult to give specific recommendations here, refer to the reference documentation.
As we always say, if there is a problem with the computer or the operating system, one of the first diagnostic measures should be a full scan for viruses. This will avoid difficulties in the future. As you probably know, a virus infection can interfere with the normal functioning of the computer, even when everything is configured correctly.
So, if you checked the connection of all peripheral components, and also made sure that there is no virus infection, you can try to reproduce the sound. If you get the message " audio output not installed", in Windows 7 or any other OS, it is worth checking the correctness of the driver installation. We will talk about this in the third chapter.
Connecting sound devices
As a rule, the bulk modern computers Comes with built-in sound cards. You will only need to connect two 3.5 inch plugs from headphones and speakers to the appropriate connectors. The scheme is as follows:
The green connector is used to connect audio playback devices - speakers and headphones. Pink - for recording devices (microphone). If your sound card is not color-coded for the jacks, corresponding miniatures should be indicated in front of them.
Connect the plug of the device to the appropriate connector, and check whether the sound is playing. You will probably see the message again that the audio device is not installed. In this case, do not despair. Most often, the problem is solved by installing the appropriate drivers.
Audio Drivers
In conclusion, this material we will consider probably the most important point.
So what to do if an audio device is not installed. Or rather, if you see such a message on the screen of your monitor. You should install the correct driver.
- When you purchase new computerThe bundled distribution should include the main software distributions. Including the driver of all installed devices. Use it to install
- In the event that it did not turn out, you need to find out what brand and model of sound card is used in your computer, and then find the appropriate driver in the Internet.
- You can use special software packages that allow you to find drivers for your hardware. The driver pack solution is considered to be the most effective.
It will be useful for you: if you make a mistake and have installed a problem driver that does not allow the operating system to start, use the system recovery tool and return it to working condition.

Conclusion
Now you know what to do if the output audio device is not installed. If you have any questions, you can always contact us for help.
If you do not take care of the security settings, your network may be exposed.
For identification in the network, computers are used.
Why look for information on other sites, if everything is collected from us?
Only the correct connection and setup of a computer can guarantee high-quality sound reproduction. This process is quite simple. Simple recommendations and full adherence to them will help to avoid an error called “ Audio output device not installed".
The main reasons for the lack of sound on the device
To identify the causes, special attention should be paid to the operation of headphones, speakers and a sound card. It is very important to understand exactly when there is no sound. If it is absent when playing a game, then you need to check whether the game settings are correctly set Only reference recommendations will help solve the problem of this nature.
In the event that a problem has arisen in the operating system, the first thing to do is to carefully check it for viruses. For these purposes, you can either use the antivirus or the hotel. This procedure will help get rid of problems that may arise in the future. Even if all the settings are made in the correct way, but there are viruses, this can lead to serious disruptions in the operation of the entire system.
If nevertheless antivirus program blocks the process of the game or any other, then you can, while the game is running. After exiting it, it is necessary to activate the antivirus again.
If no virus infections are detected, and a detailed check of the peripheral components is performed, then you can safely turn on the sound. If an error is returned, the problem is most likely in the drivers of the operating system.
Sound devices
Often, when building computers, manufacturers build sound cards. Therefore, their owners only need to connect the plugs from the headphones to one connector, and from the speakers to the other. The whole process should follow a specific pattern. Connectors with different colors differ in function. Green color corresponds to the devices that reproduce the sound - headphones, speakers. The pink connector is used to connect a microphone. Even if the nests are not color-coded, miniature pictures are necessarily indicated next to them.
We connect the plugs to the appropriate connectors, after which the sound should be played. If this does not happen, then the problem is in the drivers.
Driver check
The main cause of the error is incorrect installation of drivers. It is possible to prevent its occurrence, if you check the availability of distributions of the main software, including drivers, even when buying a computer.
If there are none, then you need to clarify the model and brand of the sound card in order to download them to a computer afterwards. You can also use special programs, thanks to which the search for drivers will pass without problems. After you need to configure the driver. If problems arise with them, the system will report this by the appearance of a yellow triangle, inside which there is an exclamation mark.
As soon as the appearance is noticed sound card, you need to select the item with the name "Driver". Then we download all the updates. Often the process occurs automatically. If the download of updates will be interrupted, then immediately select the function “Roll back”. This will allow you to install the original version, which can be safely updated in the future.
After restarting the computer everything should work out. However, if it did not work out, then you need to restore the system. Go to the "Point", go to the "Program". We find the control point and are engaged in OS recovery. In 99% of cases, this is exactly what helps to forget about an error that previously prevented high-quality sound reproduction.
