NAME
       alsactl - advanced controls for ALSA soundcard driver


SYNOPSIS
       alsactl [options] [store|restore] <card # or id>


DESCRIPTION
       alsactl	is  used  to control advanced settings for the ALSA soundcard
       drivers. It supports multiple soundcards. If your  card	has  features
       that you can't seem to control from a mixer application, you have come
       to the right place.


INVOKING
       alsactl [options] [store|restore] <card # or id>


   Commands
       store saves the current driver state for the selected soundcard to the
       configuration file.

       restore loads driver state for the selected soundcard from the config-
       uration file.

       If no soundcards are specified, setup for all cards will be  saved  or
       loaded.


   Options
       -h, --help
	      Help: show available flags and commands.


       -f, --file
	      Select   the   configuration   file  to  use.  The  default  is
	      /etc/asound.state


       -F, --force
	      Used with restore command.  Try to restore the matching control
	      elements as much as possible.


       -d, --debug
	      Use debug mode: a bit more verbose.


       -v, --version
	      Print alsactl version number.


FILES
       /etc/asound.state  (or  whatever file you specify with the -f flag) is
       used to store current  settings	for  your  soundcards.	The  settings
       include	all  the  usual	 soundcard mixer settings.  More importantly,
       alsactl is capable of controlling other	card-specific  features	 that
       mixer apps usually don't know about.

       The  configuration  file is generated automatically by running alsactl
       store. Editing the configuration file by hand  may  be  necessary  for
       some  soundcard	features (e.g. enabling/disabling automatic mic gain,
       digital output, joystick/game ports, some future MIDI routing options,
       etc).
