6. Perform a Driver Rollback

If you have an external sound card and have installed an update, try a driver rollback. A new driver update can sometimes create more problems than it intends to fix. You can use the device driver rollback feature in Device Manager to undo the changes and reinstall the older version of the driver.

You can roll back a driver using Windows Device Manager . In Device Manager, expand theSound, Video, and Game Controllers section. Next, access your external sound card properties to perform a rollback.

If the Roll Back Driver option is greyed out, it means the option is unavailable for the selected device. In this instance, uninstall the existing audio device driver and download an older version of the driver from your sound card manufacturer’s website. Your sound card manufacturer may also have a newer driver version available. If available, install the latest version and check for any improvements.

7. Install Pending Windows Updates

If it is a Windows-specific issue, installing pending Windows updates can fix the problem. Check the Windows updates page for newer updates and install them to see if that helps resolve the issue.

Typesndvol and clickOK to open Volume Mixer.
TheApplication column will show all the apps using your audio device.

To close the app, open the system tray, right-click the app icon, and selectQuit . You can also force close the app using Task Manager. If the issue persists, uninstall the problematic app to restore the audio to your computer.

Fixing the Audio Device in Use By Another Application Error

This error is often the result of an audio device driver problem. To fix the error, check if a new driver is available. If not, perform a rollback to install the previous driver version. Also, disable exclusive application access to audio devices and configure the Windows Audio service to start automatically.
