Laptop Audio Problem

I have an Acer Aspire 7720

T8100 2.1GHz Core2Duo
3GB DDR2-667
Nvidia 8600M GT 512MB

It originally came with Vista Ultimate 64-bit and I had a lot of audio problems with scratchy, choppy sound. The computer seemed to go in slow motion while this happened.

I recently reformatted and installed Windows XP Pro 32-bit, and after getting all of the drivers, I'm still getting the same problems.

The audio choppiness happens quite often, when I stream videos, or play .mp3s, or even generic windows sounds. Sometimes it works perfectly, and other times it's awful.

The CPU usage and RAM usage do not spike when this happens, but it sure seems like my computer is lagging while this takes place. The audio is the most noticeable problem.

Any and all help would be greatly appreciated.
