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.
