 Makes no sense to me, either.  Maybe he's got extra stuff running when he
is logged in as an unpriviledged user.  Jason: do you have two xterms, one
with a root shell and one with a user shell, and you're running the same
program with the same arguments from either one?  Or are you doing a whole
login as root or as user?  If you are logging in differently, then maybe
something else is doing something while you're playing your sound.

 Or, maybe when you run as root your MP3 player sets its niceness negative,
so it gets higher scheduler priority.  That would help get rid of skips on a
machine just barely fast enough to decode MP3s.

 That still shouldn't make it skip, I don't think.  You can do everything
with just /dev/dsp and IOCTLs.  (you adjust the volume in a different place,
but not touching it wouldn't cause skips!)
