Splinter Cell: Chaos Theory Problem

[Reckoner]

Hey guys, I'm having a problem with my sound in Chaos Theory. I'll hear the background sound, as well as weapons firing, but I can't hear the terrorists speak when interrogating them. I also can't hear any voice dialog between lambert and fisher. I have an Audigy 2 Value w/Klipsch ProMedia 2.1's, and the sound works fine in all other games. I'm also updated to Patch 1.03 for the game.


Any ideas?

I don't know, but I get sound stutters when terrorists talk during gamplay. I'm using onboard soundchip from realtek.
