Hi,
after installing Debian bullseye I can't get sound to work. I'm using
lightdm + dwm, and I have pulseaudio installed. "pavucontrol" ist stuck
on the message "Establishing connection to PulseAudio. Please wait..."
I don't understand zilch about how sound on Linux works, but my
previous version of Debian on the same hardware worked.
NB, this is a fresh install, not an upgrade from buster (?).
You have to tell us more about your system. My crystal ball says you
probably missing some firmware for a sound adapter from Intel.
Install firmware package from a 'non-free' section and see if that will
help:
# apt install firmware-intel-sound alsa-utils
To test the audio use 'speaker-test' utility:
$ speaker-test -c2 -t wav
Also check if any channels were accidentally muted using 'alsamixer'
utility.
If you still don't have any sound, send output from commands below with
your next message:
$ lspci -knnv | grep -A6 Audio
$ aplay -l
$ aplay -L | grep -A1 ^hw:
# journalctl -b -g pulse

With kindest regards, Alexander.
