lost sound output from MOTU M2 audio interface

[atomGit]

lost all sound output from my MOTO M2 audio interface as a result of the alsa-ucm-conf upgrade from 1.2.7.1 to 1.2.8

reproduce: Manjaro KDE/Plasma Firefox v106.* MOTU M2 alsa-ucm-conf 1.2.7.1 / 1.2.7.2 pipewire 0.3.59-2 wireplumber 0.4.12-1 EasyEffects (+ add some effect) 6.3.0-1

if Firefox audio output is routed through EasyEffects, sound is lost

solutions:

• disable Firefox in EasyEffects
• downgrading to 1.2.7.1 + reboot (1.2.7.2 doesn’t work either)

This was an issue here https://github.com/alsa-project/alsa-ucm-conf/issues/190. I currently have audio working with my m2 with Arch 6.0.6-arch1-1. Although journalctl -p 3 -b results in: pulseaudio[1132]: Failed to enable ucm device Mic2. pulseaudio[1132]: Failed to enable ucm device Mic1 Alsa-ucm-conf 1.2.7.1 was fine. 1.2.7.2 was broken. Arch recently updated to 1.2.8.1 https://archlinux.org/packages/extra/any/alsa-ucm-conf/

Let me know if there is any output you would like.

for me this issue is still present with 1.2.8 and kernel 6.0.8

Could you attach the debug dump from the pulseaudio ?

After boot.

journalctl -p 3 -b

systemctl --user stop pulseaudio.socket

systemctl --user stop pulseaudio.service

(some kind of seemingly infinite loop of output)

After stopping those services -> no audio. After starting those services -> no audio...

I hope this helps.

It does not - the daemon is running:

E: [pulseaudio] pid.c: Daemon already running.

The stop procedure does not work correctly on your system. Use ps to check processes for example.

Stale. Closing, re-open if required.
