If I were you, I would completely uninstall the Realtek drivers and the Realtek
HD Audio Manager and reinstall the latest drivers.
1. Download and save to a folder on your desktop the latest (ver. 1.72) drivers

OK.

the Set Default button. Use the Configure and Properties buttons to set up your
speakers.
