### BEGIN INIT INFO
# Provides:          esound
# Required-Start:    alsasound $remote_fs
# Should-Start:      $network $portmap
# Required-Stop:     alsasound $remote_fs
# Should-Stop:       $network $portmap
# Default-Start:     5
# Default-Stop:      
# Short-Description: Sound daemon with network support
# Description:       Starts esound server to allow remote access to sound
#	card. To use esound locally, you do not need to start
#	this server on boot. You should edit server settings before 
#	starting it via sysconfig editor: Network/Sound/Esound
