I've done a quick port of SDL_mixer from the sources available at the SDL_mixer hompage:

http://www.libsdl.org/projects/SDL_mixer/ 

SDL_mixer is a sample multi-channel audio mixer library.

It supports any number of simultaneously playing channels of 16 bit stereo
audio, plus a single channel of music, mixed by the popular MikMod MOD, Timidity
MIDI, Ogg Vorbis, and SMPEG MP3 libraries.
