Yep, the matching is actually done on UID = GID.  I just stated the effect
and didn't bother with the cause.  (I considered it, but decided not to.)

Whoops!  You are correct.

I suspect that you should be able to use the CDROM to play audio CDs through
the headphone jack (assuming it has one, of course) without being in audio,
but you definitely have to be in group audio (or make /dev/audio, /dev/dsp,
and, preferably, /dev/mixer world-writable) if you want to play CDs through
the sound card.
