Subject: alsactl: Add path condition to alsa-store and alsa-restore services
X-Git-Tag: v1.1.0~24
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=0e864e1a3aaf79d451556064eb09052530a0a085;p=alsa-utils.git

alsactl: Add path condition to alsa-store and alsa-restore services

With alsa-restore.service and alsa-store.service, systemd invokes
alsactl at boot and shutdown times.  When this is invoked on a system
without sound cards, it results in an ugly error message from alsact

  /usr/sbin/alsactl: save_state:1590: No soundcards found...
  return code is "19"

Add ConditionPathExistsGlob checks of /dev/snd/control* devices for
avoiding unnecessary invocations of alsactl on such a system.
