.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|\fIinit\fP] <card # or id or device>
|
|
|
|
.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 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 restoring fails (eventually partly), the init
|
|
action is called.
|
|
|
|
\fIinit\fP tries to initialize all devices to a default state. If device
|
|
is not known, error code 99 is returned.
|
|
|
|
If no soundcards are specified, setup for all cards will be saved or
|
|
loaded.
|
|
|
|

.TP
|
|
\fI\-i, \-\-initfile\fP #=#

|
.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).
