Thanks for responding Georgi,
I had already tried "alsactl init" earlier based on other advise found
on the WWW. However, I did not pay close enough attention because of
error messages I get as shown below:

I cannot find much about this message, nor how to correct it.
The alsamixer seems to work fine as expected and indicates I have the
sound card active and should hear sound.
But, it only provides actual sound if I am root.

Hi James,
try to run:
# alsactl init
as root, reboot and adjust all channels with alsamixer or similar with
your (non-root) user.
Kind regards
Georgi

I have not received a response yet, but I am hoping.
What I know:
-sound works as root, not as user
-snd_oxygen module (required driver for my card) is loaded, but I can't
verify what is loading it. no messages in dmesg show it being loaded
-since snd_oxygen is loaded, it makes sense that aplay works as root
-pulse does not show the sound card, but does show the hdmi audio on my
nvidia card, and the microphone on my web cam. Both are muted in
pavucontrol
-big question: why doesn't sound card get loaded by pulseaudio ? How
can I force that
-I am now going over every occurrence of a pulseaudio configuration file
on my system for a clue
Any help appreciated. Is there a good troubleshoot procedure for
debian/11/bullseye sound problems ?

Hello,
I am a long-time debian user, and just recently upgraded my buster
amd64 machine to bullseye. Essentially everything works as expected
so far. However, one very nagging problem I currently have is that my
sound does not work unless I am rooted. For example, if I issue the
command
aplay bark.au
where bark.au is a snippet sound file of a dog barking, it fails.
However, if I issue the command
sudo aplay bark.au
it works fine. Similar sound playing occurs with any sound-playing
app. For example mpg123, vlc, etc., all require a sudo or be logged
in as root to work.
I have looked all around the WWW to try to find a solution to this
problem. The most common solution is to make sure that user ids are
in the audio group in the /etc/group configuration file. Of course, I
have that, and have confirmed it. This is not a brand new
installation after all, but an upgrade.
Other common remedies I have tried are to fiddle with the pavucontrol
and alsamixer settings. My sound card does not show up in the
pavucontrol (pulse doesn't find my sound card), but DOES show up in
the alsamixer.
I have also looked at the debian sound wiki, and other sources to try
to fix this problem.
Then, I remembered that I often used this form to learn about debian
way back in the days when I first started using debian about 1994 or
so. Perhaps I can get some expert help. Maybe a source I can go down
a list of troubleshoot to nail this one down. It is obviously a
permissions issue (I also looked at device permissions, etc.).
Just a bit puzzled and frustrated.
P.S.
BTW, my sound card is a C-Media, Xonor DG with chip set CMI8788 and
uses the oxygen HD audio driver.
lspci -v output corresponding:
05:02.0 Multimedia audio controller: C-Media Electronics Inc CMI8788
[Oxygen HD Audio]
Subsystem: ASUSTeK Computer Inc. CMI8786 (Xonar DG)
Flags: bus master, medium devsel, latency 64, IRQ 22, NUMA node 0
I/O ports at e800 [size=256]
Capabilities: [c0] Power Management version 2
Kernel driver in use: snd_oxygen
Kernel modules: snd_oxygen
Nothing has changed with the hardware, and I know the setup works.
This seems to be a permissions/software issue.
