[SOLVED] ALSA/Pulseaudio only Dummy Sink

After a normal update, restart of GDM and relogin into GNOME ALSA/Pulseaudio stopped recognizing my Sound Card showing only the Dummy sink.
Sound worked until the restart of Pulseaudio together with the GNOME session, which i admit ran a bit long for about 2 months, i installed updates regularly but just never restarted the GNOME session so i can't say at which point ALSA/Pulseaudio started this behavior...

Running aplay -l as a user returns:

Here are some things i tried with no luck:

  • pacman -Syu

  • latest normal and lts kernels

  • Updated UEFI-Firmware

  • removing ~/.config/pulse ~/.pulse

  • reinstalling and resetting Pulseaudio/ALSA

  • adding and removing myself from the audio group

  • countless reboots

The output of the pa-info script from freedesktop.org and syslogs:

as user: https://pastebin.com/PCqwh949
as root: https://pastebin.com/Qr6fvJPS
diff from those two: https://pastebin.com/vbTG8vtq
pulseaudio log form when it worked: https://pastebin.com/cuTuxghe
Pulseaudio log with log-level=info: https://pastebin.com/bWmVi9Jk

Im completely out of ideas this is the first issue which i cannot solve by myself, any help is greatly appreciated.

Re: [SOLVED] ALSA/Pulseaudio only Dummy Sink

You have a broken user level ALSA configuration, what's in your /home/ikarus/.config/alsa/asoundrc (and maybe ~/.asoundrc , ~/asound.conf )? And the permissions of these? Why do they exist? Maybe post

strace aplay -l

Re: [SOLVED] ALSA/Pulseaudio only Dummy Sink

That is interesting as i don't have any ALSA user config files ~/.config/alsa/asoundrc, ~/.asoundrc, ~/asound.conf none of these files exist.

Re: [SOLVED] ALSA/Pulseaudio only Dummy Sink

Is an environment variable set or so?  It's not looking at the system config directories like /usr/share/alsa and /etc/alsa/conf.d where it should grab default configuration information.

Re: [SOLVED] ALSA/Pulseaudio only Dummy Sink

This is indeed my fault. i must have copied this environment variable while trying clean $HOME directory from all those dotfiles.
After removing the ALSA line from my ~/.profile file, running systemctl --user unset-environment ALSA_CONFIG_PATH and killing my session Pulseaudio works again. smile
Wow that i didn't think of this, thank you so much i am so sorry for wasting your time...

Amazing that a  little environment variable and not restarting your session can make so much trouble.
