Well, the problem isn't that there's no sound, although that's a
symptom. There's no sound because, for some reason I cannot fathom, FC2
thinks the user doesn't have permission to access the alsa device files.

Yes, it's definately a permissions issue. The problem is... I think the
alsa device files *are* set up correctly. Everything in /dev/snd/* has
permissions of crw-rw---- with ownership of <user>.users and each <user>
belongs to the users group.

Thanks for adding another set of eyballs, though. Maybe you'll find that
clue stick that's been eluding me...
