It happened when I was running the Spysweeper program. I had AIM, IE and iTunes on as well. I was talking to someone on IM and I noticed the IM sound sounded like it was underwater. Then when I played an MP3, it started doing that skip I mentioned eariler. I noticed when I did put Spysweeper on "pause", everything else would run faster obviously and the sound would be fine. But after I had closed that program the sound never was the same.
