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 configuration 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).
