How can I fix Realtek soundcard driver issues in Windows 10?

The issue might be caused by the new DCH drivers, but it’s not confirmed.

Taking into consideration the fact that restoring doesn’t solve the issue, you might want to try to uninstall all your current sound drivers and reinstall them from the manufacturer’s website.

If you want to completely uninstall your sound drivers in Windows 10, use the best uninstaller software from this article.

If the Windows default sound drivers are the problem, this solution might work for you.

After installing the new drivers, you’ll have to make sure that Windows won’t automatically update them in the future. To do that, follow the simple steps from this useful guide.
