### BEGIN INIT INFO
# Provides:          alsa-utils
# Required-Start:    $local_fs $remote_fs
# Required-Stop:     $remote_fs
# Default-Start:     S
# Default-Stop:      0 1 6
# Short-Description: Restore and store ALSA driver settings
# Description:       This script stores and restores mixer levels on
#                    shutdown and bootup.On sysv-rc systems: to
#                    disable storing of mixer levels on shutdown,
#                    remove /etc/rc[06].d/K50alsa-utils.  To disable
#                    restoring of mixer levels on bootup, rename the
#                    "S50alsa-utils" symbolic link in /etc/rcS.d/ to
#                    "K50alsa-utils".
