I recently had to remove my SB Audigy LS piece of crap sound card (it broke) and am forced to rely on my even crappier on-board sound, SoundMAX Integrated Digital Audio. When I try running Dragonshard, I get a bunch of popping from my speakers (Logitech 5.1 surround, can't remember the model number, I can find it if it's important), then no sound at all, except a slight rumbling from my subwoofer. Upon exiting the game, I find that this is not just a problem in the game, but system-wide. I reboot and sound returns to normal and works fine in every game, until I try Dragonshard again, then the same popping followed by system-wide broken sound returns. I have tried messing with hardware acceleration and sample rate conversion, but it makes no difference. I even disabled the surround speakers and left just the standard left and right stereo connected and it does the same thing. Anybody got any ideas on this one?

EDIT - Another minor wrinkle: after physically disconnecting all but the stereo speakers and running the game, sound was broken, but when I reconnected the center/sub and surround, they started working again, but the front/stereo that were connected when I ran the game continued to not work.
