When I attempt to run dxdiag it will say error: problem getting extra sound info. When I run itunes it says the audio configuration is incorrect and audio/video playback may not work correctly. If I run quicktime with video it will run the video but not sound will play.
I have run eusing registry cleaner, un installed and re installed the audio driver, reset bios to default, updated windows, un inst and re inst quicktime/itunes/silverlight, defragged, but nothing has changed. What else could it be?
