i feel hwdep would be more appropriate.

i guess he wants the sound engine, mixing of several streams and
running efficiently (almost in background) for games, etc.
it's less music-oriented, but would need just a sample load and
loop playback function (with panning, volume effect if possible).
at least, it wouldn't be too difficult to implement it for emu10k1
(and maybe trident and ymfpci, too, if the sample size is small).
