How to fix the error "output audio device is not installed" in Windows 7

One of the reasons why there may be no sound on computers running Windows 7 is an error "The output device is not installed". Let's figure it out, what is the essence and how to deal with the specified problem.

If the need to eliminate the problems could not correct the situation, then in this case, go to the following ways to eliminate the fault with the sound described in this article.

Method 2: Enabling audio device in "Control Panel"

If this error occurs, you must check whether the audio device is disabled in the "Control Panel" section that is responsible for the sound.

1. Click "Start" and go to the "Control Panel".



2. Go to the "Equipment and Sound" section.



3. Click on the inscription "Sound devices" in the "Sound" block.



4. A sound control tool opens. If the options for the connected headset are displayed in it, you can skip this step and immediately move to the next step. But if you will only see the inscription "Sound devices that are not installed" in the opened shell, you will need to produce an additional action. Click the right mouse button (PCM) along the inside of the window shell. In the context menu, select "Show disabled ...".



5. All disconnected devices will be displayed. Click the PCM on the name of that of them through which you wish to output the sound. Select the option "Enable".



6. After that, the selected device will be activated. You will be left to the "OK" button.



7. The problem with the error we studied will be solved and the sound will start output.

Method 3: Enable audio adapter

Another reason for the error described by us can be disabled an audio adapter, that is, the PC sound card. You can use it by making manipulations in the Device Manager.

1. Go to the control panel in the same way that was previously described. Open the System and Security section.



2. In the system "System" click on the "Device Manager" inscription.



3. The window of the specified "dispatcher" opens. Click on the name of the "Sound Devices ..." section.



4. A list of audio cards and other adapters will open. But it may be in the list and only one element. Click the PCM on the name of the sound card, through which the sound on the PC should be displayed. If the "Disable" item is present in the opened context menu, it means that the adapter is enabled and you need to look for another reason for the problem with sound.

   

   If, instead of the "Disable" item in the specified menu, you observe the "Enable" position, it means that the sound card is deactivated. Click at the specified item.



5. A dialog box appears in which the PC restarts will be prompted. Close all active applications and press "Yes."



6. After rebooting the computer, the audio adapter will turn on, which means that the problem with the error of the output device will be solved.

Method 4: Installing Drivers

The next factor that may cause the problem being studied is the lack of necessary drivers on the computer, their incorrect installation or failures. In this case, they must be installed or reinstall.

First of all, try reinstalling those drivers that are already available on the PC.

1. Go to "Device Manager" and, entering the "Sound Devices" section, click the PCM on the name of the desired adapter. Select "Delete" option.



2. A warning window will open, which says that the audio adapter will be removed from the system. In no case, do not install the check mark opposite the inscription "Delete Driver Programs". Confirm your actions by clicking OK.



3. Audio device will be deleted. Now you need to connect it again. Click on the "Manager" menu on the "Action" and select "Refresh the configuration ...".



4. The audio device will be found and re-connected. This will reinstall the drivers on it. Perhaps this action will solve the problem with the error we study.

If the described method did not help, but the error appeared quite recently, that is, the likelihood that the "native" drivers of your audio adapter were separated.

They could be damaged or retired due to some kind of failure, reinstalling the system and some user actions, and instead of them there was a set of standard analogue of Windows, which does not always work correctly with some sound cards. In this case, you can try to roll back the driver.

1. Open the Device Manager, go to the "Sound Devices ..." section and click the name of the active adapter.



2. In the window that opens, go to the Driver tab.



3. In the displayed shell, click on the button "Radd back".



4. The driver rollback will roll back to the previous option. After that, reboot the PC - perhaps problems with sound will stop disturbing you.

But maybe this option is that the button "roll back" will not be active or after rollback no positive changes will occur. In this case, you need to re-install the sound card driver. To do this, simply take the installation disk that was supplied with the audio adapter, and install the necessary objects. If you have it for some reason, you can go to the official website of the sound card manufacturer and download the latest updated option.

If you can't do it or do not know the address of the manufacturer's website, then you can search for drivers on the audio card ID. Of course, this option is worse than the installation from the official website of the manufacturer, but in the absence of another exit you can use it.

1. Go back to the sound card properties window in the Device Manager, but this time go to the "Details" section.



2. In the shell opening from the drop-down list, select the option "Equipment ID". Information with the audio adapter ID will open. Click on its PCM value and copy.



3. Run the browser and open the Devid DriverPack site. The reference to it is presented below in a separate material. On the page that opens in the input field, insert the previously copied ID. In the "Windows version" block, select the number "7". On the right, specify the discharge of your system - "x64" (for 64 bits) or "x86" (for 32 bits). Click on the "Find Drivers" button.



4. After that, results with search results will open. Click on the button "Download" opposite the highest option in the list of option. It will be the latest version of the desired driver.



5. After the driver boot occurs, run it. It will be installed in the system and replace the standard version of Windows. After that restart the computer. We studied the problem should be eliminated.

Lesson: Search for drivers on the device ID

If you do not want to make the above actions to search for ID drivers, you can do everything easier by installing a special program for searching and installing drivers. One of the best options is Driverpack Solution. After starting this software, automatic OS scanning will occur for all necessary drivers. In the absence of the desired driver option, it will be automatically loaded and installed.

Method 5: System Restore

If you have no problems with the output audio device, it has not been earlier and it appeared not so long ago, and all the above solutions did not help, then you can try to restore the system with the help of various options.

First of all, you can check for the integrity of system files. They may be damaged due to various failures or viral infection. By the way, if there are suspicions for the presence of viruses, be sure to check the anti-virus utility system.

Directly scanning a system for damaged files can be performed via a "command line" in standard mode or from the recovery environment using the following command to this:

SFC / SCANNOW.

If there is no system file detection or disorders in their structure, the procedure for restoring damaged objects will be performed.

If the above option has not brought the desired result, but you have a backup copy of the system or a recovery point created before the problem arose with sound, you can make a rollback to it. The disadvantage of this method is that not all users have a predetermined system backup system, which meets the condition described above.

If none of the listed options helps, and you do not have the right backup, then it remains to reinstall the system to correct the situation.

As you can see, there are quite a few causes of an error with an installation of an output device. Accordingly, for each factor, there is a group of ways to eliminate the problem. It is not always possible to immediately establish the immediate cause of the specified problem. Therefore, use methods in the order of their complications: the way they are listed in the article. The most radical methods that include recovery or reinstalling the system, use only when the remaining options did not help.
