Asus P5P800 Sound Problem

Hello,
I am having a problem with the sound output on an Asus P5P800 with integrated SoundMax Digital Audio. There IS sound coming from the speakers; however, the volume is low and the quality sucks. Everything is at it's max in Volume Control and SoundMAX control panel so I'm stumped.

I tried updating the drivers but I still have the same problem.

The speakers do work fine on other computers so I don't think the problem has to do with the speakers.

Any suggestions are greatly welcomed, Thanks
