What's your audio hardware and what SDL version are you using ? If 
that's some AC97 card and your version of SDL is 1.2.7 or older, you 
might want to set the SDL_DSP_NOSELECT environment variable. However, it 
has been removed in later SDL versions so there is no solution if you 
run 1.2.8 or higher (short of patching SDL of course).
