[Pkg-alsa-devel] Bug#872479: alsa-utils: alsa-restore.service uses /run which is tmpfs

[Grand T]

To ensure a full restore of all level ( PCM for example) i modify the service as below


[Unit]
Description=Save/Restore Sound Card State
Documentation=man:alsactl(1)
ConditionPathExists=!/etc/alsa/state-daemon.conf
ConditionPathExistsGlob=/dev/snd/control*
After=alsa-state.service

[Service]
Type=oneshot
RemainAfterExit=true
ExecStartPre=/bin/sleep 60
ExecStart=-/usr/sbin/alsactl -E HOME=/var/lib/alsa restore
ExecStop=-/usr/sbin/alsactl -E HOME=/var/lib/alsa store

So it is much better and done after all snd management
