Looking a bit further it seems that /var/lib/alsa/asound.state doesn't
exist.
That means that we are facing a chicken-egg problem here, the file will
never be created as the service is never started (and then never
stopped).
I don't know, if it helps, but I could manually create a working
settings file with:
alsactl -f /var/lib/alsa/asound.state init
alsactl -f /var/lib/alsa/asound.state store
In the shell:
root@debian:/var/lib/alsa# alsactl -f /var/lib/alsa/asound.state init
Found hardware: "ICH" "Analog Devices AD1881A" "AC97a:41445348" "0x1043"
"0x11d4"
Hardware is initialized using a generic method
root@debian:/var/lib/alsa# ls -l
insgesamt 0
root@debian:/var/lib/alsa# alsactl -f /var/lib/alsa/asound.state store
root@debian:/var/lib/alsa# ls -l
insgesamt 8
-rw-r--r-- 1 root root 5680 Apr 7 18:55 asound.state
root@debian:/var/lib/alsa#
Since then, the sound level was properly saved and restored on restart.
/var/log/syslog on start:
Apr 7 19:41:46 debian systemd[1]: Starting Save/Restore Sound Card State...
Apr 7 19:41:46 debian systemd[1]: Started Save/Restore Sound Card State.
Apr 7 19:41:46 debian systemd[1]: Reached target Sound Card.
/var/log/syslog on shutdown:
Apr 7 19:45:17 debian systemd[1]: Stopped target Sound Card.
Apr 7 19:45:17 debian systemd[1]: Stopping Save/Restore Sound Card State...
I doesn't say "Stopped Save/Restore Sound Card State.", though. So the
last confirmation seems to be missing. But it still works, as far as I
can tell...
I think, I always needed to run "alsactl init" at least once since
Debian 8 Jessie, and this is still mentioned in the Debian Wiki:
Configure alsa by running the command 'alsactl init' as root. Then
reboot and try to test your sound.
