Do you have the problem when playing music or video CDs ?
The sound is garbled in sync with my mouse movements and keystrokes in both Real Player and Windows Media when I browse the net or work on a document. It just started to happen after I loaded XP Service Pack 2. Any suggestions as to how to fix it?
