Luxinia does currently (0.98) support simple wav files for playback. Soundsources can be positioned in space same as a sound listener. OpenAL? will then mix a 3D sound effect using the computer's soundcard. Sounds can be modified variously during playback, changing its gain or pitch.
Via Ogg Vorbis it's possible to play one "sterero music" file in the background as well.
You can switch OpenAL? renderers, and a software reference implementation exists as well if hardware support is lacking.
