.TH ALSAMIXER 1 "15 May 2001" .SH NAME alsamixer \- soundcard mixer for ALSA soundcard driver, with ncurses interface .SH SYNOPSIS \fBalsamixer\fP [\fIoptions\fP] .SH DESCRIPTION \fBalsamixer\fP is an ncurses mixer program for use with the ALSA soundcard drivers. It supports multiple soundcards with multiple devices. .SH INVOKING \fBalsamixer\fP [\fIoptions\fP] .SS Options .TP \fI-h, -help\fP Help: show available flags. .TP \fI-c\fP Select the soundcard to use, if you have more than one. Cards are numbered from 0 (the default). .TP \fI-D\fP Select the mixer device to control. .TP \fI-g\fP Toggle the using of colors. .TP \fI-s\fP Minimize the mixer window. .SH KEYBOARD COMMANDS \fBalsamixer\fP recognizes the following keyboard commands to control the soundcard. .SS General Controls The \fILeft\fP and \fIright arrow\fP keys are used to select the channel (or device, depending on your preferred terminology). You can also use \fIn\fP ("next") and \fIp\fP ("previous"). The \fIUp\fP and \fIDown Arrows\fP control the volume for the currently selected device. You can also use \fI+\fP or \fI-\fP for the same purpose. Both the left and right signals are affected. For independent left and right control, see below. The \fIB\fP or \fI=\fP key adjusts the balance of volumes on left and right channels. \fIM\fP toggles muting for the current channel (both left and right). If the hardware supports it, you can mute left and right independently by using \fI,\fP (or \fI<\fP) and \fI.\fP (or \fI>\fP) respectively. \fISPACE\fP enables recording for the current channel. If any other channels have recording enabled, they will have their recording function disabled first. This only works for valid input channels, of course. \fIL\fP re-draws the screen. .SS Quick Volume Changes \fIPageUp\fP increases volume by 5. \fIPageDown\fP decreases volume by 5. \fIEnd\fP sets volume to 0. You can also control left & right levels for the current channel independently, as follows: [\fIQ\fP | \fIW\fP | \fIE\fP ] -- turn UP [ left | both | right ] [\fIZ\fP | \fIX\fP | \fIC\fP ] -- turn DOWN [ left | both | right ] If the currently selected mixer channel is not a stereo channel, then all UP keys will work like \fIW\fP, and all DOWN keys will work like \fIX\fP. .SS Exiting Quit the program with \fIALT Q\fP, or by hitting \fIESC\fP. Please note that you might need to hit \fIESC\fP twice on some terminals since it's regarded as a prefix key. .SH SEE ALSO \fB amixer(1), aplay(1), arecord(1) \fP .SH BUGS Some terminal emulators (e.g. \fBnxterm\fP) may not work quite right with ncurses, but that's their own damn fault. Plain old \fBxterm\fP seems to be fine. .SH AUTHOR .B alsamixer has been written by Tim Janik and been furtherly improved by Jaroslav Kysela . This manual page was provided by Paul Winkler .
