I am having issues with a Shuttle AN35 ultra with the on-board sound. I have 2 machines and they are both having the same problem.... the problem is most recognizable in Counter-strike, the sound echoes and is all crackily and digitized, also if I am playing an mp3 and lets say open a window with lots of music files in it the sound will sound choppy when the file information is gathered (like artist and track that XP loads)
