.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. .TP \fI\-V\fP Select the starting view mode, either \fIplayback\fP, \fIcapture\fP or \fIall\fP. .SH MIXER VIEWS The top-left corner of \fBalsamixer\fP is the are to show some basic information: the card name, the mixer chip name, the current view mode and the currently selected mixer item. When the mixer item is switched off, \fI[Off]\fP is displayed in its name. Volume bars are located below the basic information area. You can scroll left/right when all controls can't be put in a single screen. The name of each control is shown in the bottom below the volume bars. The currently selected item is drawn in red and/of emphasized. Each mixer control with volume capability shows a box and the current volume filled in that box. The volume percentages are displayed below the volume bar for left and right channels. For a mono control, only one value is shown there. When a mixer control is turned off, \fIM\fP (mute) appears below the volume bar. When it's turned on, \fIO\fP in green appears instead. You can toggle the switch via \fIm\fP key. When a mixer control has capture capability, the capture flag appears below the volume bar, too. When the capture is turned off, \-\-\-\-\-\- is shown. \fICAPTUR\fP in red appears when the capture switch is turned on. In addition, \fIL\fP and \fIR\fP letters appear in left and right side to indicate that left and the right channels are turned on. Some controls have the enumeration list, and don't show boxes but only texts which indicate the currently active item. You can change the item via up/down keys. .SH VIEW MODES \fBalsamixer\fP has three view modes: playback, capture and all. In the playback view, only the controls related with playback are shown. Similarly, only the controls for capture (recording) are shown in the capture view. The all view mode shows all controls. The current view mode is displayed in the top-left position together with the mixer name, etc. The default view mode is the playback view. You can change it via \fI-V\fP option. Each view mode can be switched via keys, \fIF3\fP, \fIF4\fP and \fIF5\fP keys for playback, capture and all views, respectively. \fITAB\fP key toggles the current view mode circularly. In addition to these view modes, you can switch to the help mode and the proc info mode via \fIF1\fP and \fIF2\fP keys, respectively. On terminals that can't use funtion keys like gnome-terminal, \fI?\fP and \fI/\fP keys can be used alternatively for help and proc modes. .SH KEYBOARD COMMANDS \fBalsamixer\fP recognizes the following keyboard commands to control the soundcard. Commands shown here in upper case can also be given in lower case. To be reminded of these keystrokes, hit the \fIh\fP key. .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 further improved by Jaroslav Kysela . This manual page was provided by Paul Winkler .
