NAME
       alsactl - advanced controls for ALSA soundcard driver

SYNOPSIS
       alsactl [options] [store|restore|names] <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.

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 configu‐
       ration file.

       names generates list of available device names for  applications.   The
       card  number or id is ignored for this command. The list is always gen‐
       erated for all available cards.

       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 or /etc/asound.names (for the names command).

       -F, --force
	      Used with restore command.  Try to restore the matching  control
	      elements	as  much  as  possible.	 This option is set as default
	      now.

       -P, --pedantic
	      Used with restore command.  Don't	 restore  mismatching  control
	      elements.	 This option was the old default behavior.

       -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, als‐
       actl 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).

       /etc/asound.names (or whatever file you specify with the	 -f  flag)  is
       used  to	 store	the list of device names available in your system. The
       list does not contain all virtual names,	 because  the  name  space  is
       infinite,  but it detects present hardware and generates list of common
       names. The user / system administrator  /  another  configuration  tool
       might modify the file to add virtual names as well.
