alsa-project/alsa-ucm-conf issue #131 was edited from aljazzair:

Hello.

I am on Manjaro Linux, an Arch derivative. Recently, after a system update, sound was gone. After a couple of hours investigation, I narrowed it down to an update of alsa-ucm-conf. Basically after downgrading 1.2.6.3-0 => 1.2.5.1-1, my problem is gone.

Symptom: With 1.2.6.3-0, there was no sound. Running aplay -l listed my hardware. Also I was able to hear sound from my monitor using the following command:

aplay -D plughw:0,7 /usr/share/sounds/alsa/Front_Right.wav

But pactl list sinks came back empty. Pavucontrol showed no output devices either. Rebooting several times, editing various config files did not help.

I looked at the list of recent upgrades and saw alsa-ucm-conf in the logs. Downgrading solved my issue.

Distribution:

Linux homelab 5.13.19-2-MANJARO #1 SMP PREEMPT Sun Sep 19 21:31:53 UTC 2021 x86_64 GNU/Linux

List of PLAYBACK Hardware Devices from aplay -l:

Sound managed with:

pipewire --version pipewire Compiled with libpipewire 0.3.40 Linked with libpipewire 0.3.40

I am posting this in order to document what happened in case someone has a similar issue, and searches google for hints. Also to inform the developer, maybe something can be done to avoid this.

Thank you.
