They've been root.audio from the beginning, I was just playing with some
stuff though and made some progress. These are the default permissions,
my username is cbarry and I am in group audio:

$ ls -l /dev/audio /dev/dsp
crwxrwx---   1 root     audio     14,   4 Jul 20 17:45 /dev/audio
crwxrwx---   1 root     audio     14,   3 Jul 20 17:45 /dev/dsp

I noticed I still couldn't catenate a file to /dev/audio though because
of permission denied so I changed them to this:

crwxrwxrwx   1 root     audio     14,   4 Jul 20 17:45 /dev/audio
crwxrwxrwx   1 root     audio     14,   3 Jul 20 17:45 /dev/dsp

Now this really has me confused. I can play files now as a user but I
can't use the volume control and speaker balance as they do absolutely
nothing. I'm stuck with one set volume, while again with root everything
is perfect. If I'm a member of group audio, why did I have to change the
permissions from what they were to write to /dev/audio? I really am a
newbie to the unixy way of doing things with all these permissions. I've
been using MS for too many years I guess. I guess for volume control and
speaker balance there's another /dev device but I'll be damned if I know
which one.
