very good point, the relevant call here is "snd_pcm_drain()". ALSA
allows you to close the device immediately (i.e. when you call
snd_pcm_close()), or when all data sent to the device has been played.
OSS doesn't provide an automatic way to select these behaviours, and I
recall from memory that you always get the second one.
which of these behaviours is correct is a very app-dependent issue.
