+[PATCH] assume storing is success if not sound card device
+
+Upstream-Statue: Pending
+
+Systemd will report failure when run alsa-*, if the machine has not the
+sound card. To void this annoyed message, alsa-restore/alsa-state ignore
+all the exit codes by prefixing "-" in ExecStart, like:
+
+   alsa-utils-1.0.29$ grep "=-" ./ -r|grep service.in
+   ./alsactl/alsa-restore.service.in:ExecStart=-@sbindir@/alsactl restore
+   ./alsactl/alsa-state.service.in:ExecStart=-@sbindir@/alsactl -s -n 19 -c rdaemon
+   ./alsactl/alsa-state.service.in:ExecStop=-@sbindir@/alsactl -s kill save_and_quit
+   lsa-utils-1.0.29$
+
+But alsa-store.service.in is missing, and better solution is to ignore
+the exit code 19 which means not sound card device, not all exit code
