Sound Error.

I've played crossfire for around 1 1/2 years. Ever since the beginning i've had this error. I start crossfire with sound on and and i get is laggy sound. Like when you a play a game and it begins to lag the sound becomes skippy, trippy, and annoying. The even wierder thing is.... Any other form of sound on my computer does the same thing. No other game has this problem (PW, WOW). So its not my processor, my graphics card wouldn't make my sound lag like hell so its some kind of game error. Anyone else get this or have a solution? Also i have installed and uninstalled several times. I run Windows Vista (32 Bit), AMD Athlon (2GB) Processor, NVIDIA GeForce 8200 Graphics. Ask for any other specs.
