See below... +alsamixer -c N selects the soundcard to control, where N is the number of +the card, counting from 1. +alsamixer -m selects which mixer device to control, counting from 0. This +is only applicable to soundcards that have more than one mixer to +control. It is the same as the amixer -d flag. + + +Keyboard commands: +================== + +Left & right arrow keys are used to select the channel (or device, +depending on your preferred terminology). You can also use n (next) +and p (previous). + +Up/down arrows control the volume for the currently selected device. +Both the left & right signals are controlled. +You can also use "+" or "-" to turn volumes up or down. + +"M" toggles muting for the current channel (both left and right). You can +mute left and right independently by using , and . respectively. + +SPACE toggles recording: the current channel will be added or removed from +the sources used for recording. This only works on valid input channels, +of course. + +"L" re-draws the screen. + +TAB does something interesting: it toggles the mode for volume display. +This affects the numbers you see, but not the operation of the level +controls. There seem to be two modes: one is percentages from 0-100, the +other is called "exact mode" and varies from channel to channel. This +shows you the settings as the soundcard understands them. All the channel +level ranges are from 0 to a power of 2 minus one (e.g. 0-31 or 0-63). + +Quick Volume Changes +-------------------- + +PageUp increases volume by 10. +PageDown decreases volume by 10. +Home sets volume to 100. +End sets volume to 0. + +You can also control left & right levels for the current channel +independently, +according to this chart: + +Q | W | E <-- UP +------------- +Z | X | C <---DOWN + +^ ^ ^ +| | +-- Right +| | +| +--- Both +| +Left + + +If the current mixer channel is not a stereo channel, then all UP keys +will work like W, and all DOWN keys will work like X. + + +Exiting +======= + +You can exit with ALT + Q, or by hitting ESC. + + +----------------------------------------------------------------- + +Alsamixer has been written by Tim Janik <timj@gtk.org> and +been furtherly improved by Jaroslav Kysela <perex@perex.cz>. +This document was provided by Paul Winkler <zarmzarm@erols.com>. |
