Choppy audio in cutscenes

[kaboobie]

When playing the game, the sound in all of my cutscenes is choppy. It almost seems like the movie is playing slower than the sound, and the sound is waiting for the movie to catch up before continuing. Does anybody know what might be causing this? I've already tried newest drivers/directx

I'm having a similiar problem, but my video is also choppy during the cutscenes. The audio cuts in and out shortly after a new spawn as well. hmmm...
