Well, I do (in Kobo Deluxe, which uses un unnamed predecessor to 
Audiality) - but I wouldn't really recommend using either of those 
engines for anything serious at this point. They're both effectively 
dead, and I'm working on some rather different solutions to replace 
them. (PicoSound for basic streaming/playback/mixing, new Audiality 
based on a real time scripting engine for advanced synthesis and 
ChipSound for more retro style and less CPU hungry synthesis.)

Depending on what you need though, you might be able to find some 
useful code in there. Maybe ripping the resampler (voice) code, and 
using SDL_sound for music?

Or, if you're in no particular hurry, you can wait for me to get 
PicoSound done. ;-)
