Ahhhhh! Music to my ears!
CD is playing alright. Volume Control Panel mute, volume, balance all
work. In *my* original thread (not the one from ech - Jim?), I couldn't
even open the Volume Cont... crap that's too long - VCP ;-) (you know
who you are!)
So, I suspect we have achieved bug nirvana. ISTM that the problem is
isolated to Gnome or it's interface to the system *or* a failure in some
OS component.
1) Gave (properly?) ownership of the devices to a user other than the
desktop owner (NB: *if* it is legal for a user other than desktop owner
to use the facilities because the user is "in the desktop", being
invoked from a Gnome terminal, then the device ownership should be given
to the user of the device, just as with tty devices).
2) When the using application(s) are terminated, the devices ownership
should be returned to root, as with tty devices, or back to the desktop
user (if that user ever owned them *before* the devices were used -
which they weren't in this case) allowing later allocation to another
user again and making them also available for the desktop user.
3) When ownership of the devices were manually changed to root owner,
*part* of the desktop facilities began operating normally.
4) Only part not working now is the volume control application out of
the speaker icon on my panel.
5) As you suspected, lookie here!
# cd ~hardtolove;find . -user bill -ls

The Q now is will changing ownership of these affect the volume
slider? Shouldn't? First one is an LSB shared object, second one is
data.
Anyway, with your (and all the others too) help, we have a reproducible
situation and some clues.
Before I write a bug report (after seeing that one doesn't exist),
anything else you think I could look for or try?
