.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] .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. .SH OPTIONS .TP \fI\-h, \-\-help\fP Help: show available flags and commands. .TP \fI\-d, \-\-debug\fP Use debug mode: a bit more verbose. .TP \fI\-v, \-\-version\fP Print alsactl version number. .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. This option is set as default now. .TP \fI\-P, \-\-pedantic\fP Used with restore command. Don't restore mismatching control elements. This option was the old default behavior. .TP \fI\-r, \-\-runstate\fP Save restore and init state to this file. The file will contain only errors. Errors are appended with the soundcard id to the end of file. .TP \fI\-R, \-\-remove\fP Remove runstate file at first. .TP \fI\-E, \-\-env\fP #=# Set environment variable (useful for init action). .TP \fI\-i, \-\-initfile\fP #=# The configuration file for init. By default, PREFIX/share/alsa/init/00main is used. .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). .SH SEE ALSO \fB amixer(1), alsamixer(1), aplay(1) \fP .SH BUGS None known. .SH AUTHOR \fBalsactl\fP is by Jaroslav Kysela and Abramo Bagnara .
