From some of the references I've read, I'd actually expect that
/proc/asound (and everything under it) should belong to the 'audio'
group, but none of the systems in my house actually do that, and for the
life of me I can't seem to figure out how to change that behavior.
Probably something really silly that JYA is going to point out and I'm
going to feel completely stupid, but I'm used to that by now :-).
