When you have issues with the sound or audio on your Windows 10 PC, you should run the built-in sound troubleshooter first. The troubleshooter automatically scans and fixes most of the issues. If the troubleshooter fails to detect the issue, you can try fixing the issue by reinstalling the audio driver.
But before reinstalling the audio driver, we recommend you to update the audio driver to the latest version. If the issue cropped up after updating to the latest version of the audio driver, rollback to the previous version of the driver. If none of these methods help, you can then try out reinstalling the audio device driver.
IMPORTANT: Do note down name and version of the audio driver before uninstalling them so you can easily download the right version of the audio driver. To check the version, please refer to our how to check driver version number guide.
