3 alsamixer \- soundcard mixer for ALSA soundcard driver, with ncurses interface
6 \fBalsamixer\fP [\fIoptions\fP]
9 \fBalsamixer\fP is an ncurses mixer program for use with the ALSA
10 soundcard drivers. It supports multiple soundcards with multiple devices.
14 \fBalsamixer\fP [\fIoptions\fP]
20 Help: show available flags.
23 \fI-c\fP <card number>
24 Select the soundcard to use, if you have more than one. Cards are
25 numbered from 1 (the default).
28 \fI-m\fP <device number>
29 Select the soundcard device to control, if your card has more than
30 one. Devices are numbered from 0 (the default). Not to be confused
31 with the soundcard mixer channels, which are sometimes also referred
32 to as "devices", just to be annoying. Many soundcards will only have
33 device 0. Some more complex cards may have more. This flag corresponds
34 to the -d flag for \fBamixer\fP, \fBarecord\fP, and \fBaplay\fP.
38 Start in "exact mode." This will affect the numbers you see displayed
39 for volumes, but does not affect operation of the level controls.
40 The default behavior is to show levels in percent from 0 to 100. This
41 is easy to read, but can mislead you about how much control the
42 soundcard actually lets you have. Exact mode, on the other hand, shows
43 you the settings as the soundcard itself understands them. In exact
44 mode, each channel level is between 0 and a power of 2 minus one
45 (e.g. 0-7, or 0-63). Exact mode may also be toggled while alsamixer is
46 running, by using \fITAB\fP.
49 \fBalsamixer\fP recognizes the following keyboard commands to control the soundcard.
54 The \fILeft\fP and \fIright arrow\fP keys are used to select the
55 channel (or device, depending on your preferred terminology). You can
56 also use \fIn\fP ("next") and \fIp\fP ("previous").
58 The \fIUp\fP and \fIDown Arrows\fP control the volume for the
59 currently selected device. You can also use \fI+\fP or \fI-\fP for the
60 same purpose. Both the left and right signals are affected. For
61 independent left and right control, see below.
63 \fIM\fP toggles muting for the current channel (both left and right). You can
64 mute left and right independently by using \fI,\fP and \fI.\fP respectively.
66 \fISPACE\fP toggles recording: the current channel will be added or
67 removed from the sources used for recording. This only works for valid
68 input channels, of course.
70 \fIR\fP toggle display of playback or record mixer.
72 \fIL\fP re-draws the screen.
74 \fITAB\fP toggles the mode for volume display. See description for the
80 \fIPageUp\fP increases volume by 10.
82 \fIPageDown\fP decreases volume by 10.
84 \fIHome\fP sets volume to maximum.
86 \fIEnd\fP sets volume to 0.
88 You can also control left & right levels for the current channel
89 independently, as follows:
91 [\fIQ\fP | \fIW\fP | \fIE\fP ] -- turn UP [ left | both | right ]
93 [\fIZ\fP | \fIX\fP | \fIC\fP ] -- turn DOWN [ left | both | right ]
95 If the currently selected mixer channel is not a stereo channel, then
96 all UP keys will work like \fIW\fP, and all DOWN keys will work like \fIX\fP.
101 Quit the program with \fIALT Q\fP, or by hitting \fIESC\fP.
110 There is no help screen implemented yet. Some terminal emulators
111 (e.g. \fBnxterm\fP) may not
112 work quite right with ncurses, but that's their own damn
113 fault. Plain old \fBxterm\fP seems to be fine.
