I have a Asus Xonar DG audio device, but no sound. No sound at all. When I go to my device manager, yellow exclamation points are on my Asus Xonar and on RAID controller. Asus says driver is current. AMD High Def audio device is not disabled, should it be? If I disable it would I have sound? I have to listen to 4 hrs of video for work so I have to have sound back up asap. Thanks!
