You're right, you do have to specify such things.  But when you
do, i'm quite confident that this should be possible, at least
for a variety of common cases.  Certainly raw audio data should
be playable in at least *some* fashion, and we also have a bunch
of very nice functions in the audioop module that can do automatic
conversions if we want to get fancy.

Are you talking about OSS vs. ALSA?  Didn't they at least try to
keep some of the basic parts of the interface the same?
