Ahh... 'dsp' was what I needed. On RedHat, though, all the audio stuff
just is in the root group, amd most devices that need to be generally
accessible just seem to have the world permissions.

Currently there is no 'audio' group. Doesn't seem worth creating one,
as I'm the only user!

Getting the permissions to *remain* set correctly, though, was whole 'nother
screaming session... I think I'll start a separate thread on that topic.
