.TH ALSACTL 1 "15 May 2001"
.SH NAME
alsactl \- advanced controls for ALSA soundcard driver

.SH SYNOPSIS

\fBalsactl\fP [\fIoptions\fP] [\fIstore\fP|\fIrestore\fP] <card # or id>

.SH DESCRIPTION
\fBalsactl\fP 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.

.SH INVOKING

\fBalsactl\fP [\fIoptions\fP] [\fIstore\fP|\fIrestore\fP] <card # or id>

.SS Commands

\fIstore\fP saves the current driver state for the selected soundcard
to the configuration file.

\fIrestore\fP 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.

.SS Options

.TP
\fI\-h, \-\-help\fP 
Help: show available flags and commands.

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

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

.TP
\fI\-d, \-\-debug\fP
Use debug mode: a bit more verbose.

.TP
\fI\-v, \-\-version\fP
Print alsactl version number.

.SH FILES
\fI/etc/asound.state\fP (or whatever file you specify with the
\fB\-f\fP 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
\fBalsactl store\fP. 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).
