The dialogue gets pretty annoying, so that may not be a total loss. I don't need instructions repeated to me every three seconds. I'll throw the smoke grenade whenever I damn well please!!

Yeah, but it's still very empty without the dialogs. Also, I noticed that my game actually has no music as well. I tried some solutions like setting the speaker to Studio Quality (24 bit, 48000 khz, i think), but nothin'. No dialogs, no music. Maybe it's because I'm using Vista, maybe not. I'm confused about what to do, and I have already beaten the game with no sound, only explosions and effects.
