lip 30 11:18:50 uroboros systemd[1]: Finished Save/Restore Sound Card State.

Steps to reproduce:
No sound on reboot. Changing settings in alsamixer has no effect.
Sound only appears after manually entering alsactl restore either by user or root.
alsa-restore.service status shows it's been run on boot.
errors in status show up also on alsactl restore, and aside from different line numbers show up in downgraded version, likely unrelated.
After asking on forum it was suggested to downgrade pulseaudio/libpulse and alsa-card-profiles which solved the issue.
I also had to downgrade pulseaudio-bluetooth, as such i'm also mentioning it here.
Problem started before i upgraded alsa-card-profiles, right after updating pulse among many things. so I believe it might be not related.

link to topic with more info about some strange behaviour like wrong outputs.

This task depends upon

There's been some more details about going around it and pulse being most likely culprit:

Seems like Headphone Out disables audio, Line out enables it, following which there seems to be no reaction to changes in alsa output.

Sound card has both line out and headphone out, in my case it was tested with hw connected to Headphone Output.

Is this still an issue with pulseaudio 16.0?

Hey sorry for late reply, was busy recently.
Can't tell I've gave up on pulse and switched to pipe wire some time ago.
Given nobody is having those issues I'd assume it's fixed.

I suspect this is/was a bug in the card profiles (in /usr/share/alsa-card-profile/mixer/ for PipeWire, or in /usr/share/pulseaudio/alsa-mixer/ for PulseAudio).

As an aside, generally (independent of the sound service you use), I would recommend doing

touch /etc/alsa/state-daemon.conf

which causes ALSA to start a daemon at boot that periodically saves device state instead of saving once at shutdown, which allows keeping the state of any devices that get hot-unplugged.
