In order for the sound to be correctly displayed by your audio device, you need to perform a comprehensive setup that will avoid many problems. But even when everything should work, it happens that a person receives a message stating that the output audio device is not installed. Let's see how to eliminate this error, especially since it is encountered quite often.
Causes of occurrence
As practice shows, the problem most often occurs among users of the operating systems Windows 7 and Vista. If the speakers or headphones do not show signs of life, then you need to "cure" the problem. The reasons are often simple: incorrectly installed drivers, failure of the sound card or speakers. It’s not difficult to check these elements for operability, and the driver is quite simple to install, but first you need to uninstall the old version and only then install the new one. There are also cases where sound effects are reproduced, but problems arise with a particular program or game. Do not sin on the hardware, as the cause may be hardware incompatibility or local application settings.
Audio Output Device Not Installed: Windows 7
The most necessary thing you need to do is to check your computer for viruses. This is especially true when the problem occurs suddenly. That is, everything worked, but suddenly stopped. You can use any reliable anti-virus program, and then try to restart your computer and check for sound.
If this does not help, then move on to the next step: we need to check the drivers, more precisely, the correctness of their installation and the availability of more recent versions. To do this, go to the control panel and find the “Sound Devices” tab there. Check if the driver is installed, and if necessary, update it through the official website of the developer. Let's not get ahead of ourselves and figure out how to properly connect an audio device.
Connecting speakers and headphones
Currently, most computers contain a built-in sound card. An exception may be the system unit or laptop that you built yourself and forgot about this part. Often, a sound card has several 3.5 mm connectors, usually green, blue and orange jacks. For everything to work, you must insert the plugs into the corresponding holes of the same color. That is, the green plug for the green jack, etc. The pink connector is used to connect the microphone. Green is designed to play sound from speakers, so first of all pay attention to whether it is connected. If the system writes: “Audio output device is not installed”, then try reconnecting all the wires and restarting the computer. Sometimes the cause may be a break or malfunction of the socket, in which case you need to either go to a specialist or change the cable.
Audio output device not installed: what to do or how to solve the problem
Now let's move on to the most critical part - installing drivers. By the way, if the sound is absent only in online games, then most likely the problem is in your antivirus, which blocks the passing network packets. It is enough to turn it off during the gameplay, and everything will fall into place.
To install the driver, you need to find the installation disk, if there is one, of course. In some cases, the necessary software is located along with the drivers on the motherboard, pay attention to this. If there is no disk, then you can try to use the Internet, this method is also quite simple.
Go to the "Device Manager" and find your sound card there. If something is wrong with the drivers, then next to you will see a yellow triangle with an exclamation mark inside. If there is no board at all, then reconnect it.
Driver Installation: Part 2
When the sound card appears, click on it, select “Driver”, and then “Update”. If you have a high-speed Internet connection, the process will start automatically.
If at the end you get an error about an unsuccessful update, it is recommended to select the “Roll back” function first. This will allow you to get the initial version, which can be updated to the latest. Restart your computer and enjoy the result.
If all else fails, it’s best to use System Restore. To do this, go to "Start", select "Programs", then "Utilities". Here you will need to select a control point when everything is still working (date, time) and restore the operating system. As a rule, this method helps almost everyone, but if you are not one of them, then reinstall the OS - this with a probability of 99.9% should solve the problem.
How else can you solve the problem?
There are special programs that allow you to recover damaged system files. Including those responsible for the correct reproduction of sound. One of these utilities is ezrecover. The program will do everything by itself, after which it will require a reboot of the computer.
There is another good method that allows you to quickly download the necessary driver for the sound device "Realtek". It consists in the fact that the ID card is copied in the device manager, by which the program downloads everything you need from the official site. You are guaranteed to get the necessary driver, which you only need to install. The method is suitable for those who use the operating system Vista or Windows 7.
A few important points
There is nothing complicated in setting up an audio output device yourself. For free on the net you can find the latest drivers, and the rest is a matter of time. But I would like to draw your attention to the fact that if the sound card is not displayed in the device manager, it is likely that it burned out. It can be tested on another computer or using special software.
The card can be disabled in BIOS, you should not forget about it. If you do not understand the BIOS, it is better to call a specialist who will do everything in a few minutes. This is due to the fact that it contains many system parameters, temperature conditions, equipment, etc. If you do something wrong, your computer or laptop may no longer turn on, and this will result in a more expensive repair.
Conclusion
In some cases, it makes no sense to go too deep into the problem, since the solution lies on the surface. For example, poor contact, a broken socket, etc. In such cases, damage can be found visually, but if this does not work, then use the methods described above.
If the audio output device is not installed, what should I do? We have already reviewed Windows 7 above. In addition, do not forget to remove the old ones before installing new drivers , because without this simple step you will not succeed. Use the DriverPack program: the utility automatically searches for outdated components and downloads updates for them.
That's all that can help you in finding a solution to this problem. Do not forget about updating the version of the antivirus, because it will help you avoid the defeat of not only the components of the sound card, but also the operating system as a whole.
