[op6-enchilada] Speaker becomes unavailable after a couple of boots

After installing image mobian-sdm845-phosh-12.0.tar.gz to op6-enchilada device, I've noticed loudspeaker becomes unavailable after a couple of boots. Minimal test setup is to run speaker-test and check the outcome, then checking pactl info and capturing journalctl logs. Test is done right after flashing image to device (to be nitpicking, very first boot is when partitions get increased to occupy the disk... this 1st boot is the 1st usable boot)

First boot, loudspeaker works fine

VID_20230816_131654_480px

op6log1stboot202308161317

Second boot, sound output's volume is lower than previous boot (please note Default Sink/Source is Voice_Call instead of HiFi)

VID_20230816_131900_480px

op6log2ndboot202308161319

Third boot, nothing is heard

VID_20230816_132056_480px

op6log3rdboot202308161321

Checking journalctl logs, I found the following:

Kernel does not find any soundcard? IMHO not relevant, as this is the same throughout all 3 logs

Feb 28 11:15:45 mobian kernel: ALSA device list:

ALSA is restoring configuration from previous boots, when existing. Looking at the explanation in Arch wiki, lines about alsa-state and alsa-restore seem fine. Maybe the Operation not permitted by alsactl are relevant?

Callaudio is starting: on 1st boot, it activates and then complains about no input/output being found. On following boots, it skips the soundcard and then activates without finding any suitable soundcard.

Pulseaudio complains about module-x11-xsmp initialization failing. AFAICT, that module stands for "X11 session management" and should not be relevant in a Wayland-environment like we are (?)

Pulseaudio is so kind to point me to a bug in someone else's code. AFAICT, this has been reported multiple times on alsa-lib repository for various drivers (e.g. alsa-lib#90 ) with the answer from alsa-lib developers being of the tone It is really not clear if the bug is in ALSA or PulseAudio code. The PulseAudio does not do any realtime checks. If someone can reproduce this problem with a simple test code, we can work to improve ours (alsa drivers or alsa-lib). IMHO Pulseaudio should focus on their own bugs instead of pointing other programs...

(not on 1st boot)

Feb 28 11:16:28 mobian pulseaudio[999]: ALSA woke us up to write new data to the device, but there was actually nothing to write.

worth checking kernel messages about max98927 (that components seems to be a Speaker amplifier), here I'm grep-ing the logs

same for wcd934 (that component seems an audio codec by Qualcomm ), I haven't found much by searching for this, just one guy with similar issue a couple of years ago solved by upgrading, IMHO not applicable to our case

Worth reading: other relevant issue reports

no sound on op6t-fajita for sdm845, here it's stated that sound cannot work in Mobian as we are (were?) lacking q6voiced. They seem to have found a solution but then it broke again...
audio routing on op6-enchilada for pmOS and PlaMo, this was then closed as a duplicate of the following one. One user reports they were able to solve the issue by playing with pavucontrol (which did not happen to me).
audio setup gets screwed after a couple of calls on op6-enchilada for pmOS 22.12 and Phosh: last 2 comments are opposite, one seem to have solved by playing some sound between one call and the next, while the other user reports pmOS edge to be broken again
