It causes alsamixer to display 2 different views of the mixer controls. One view shows only the "Playback" controls, the other view shows only the "Capture" controls, with a hidden mode (Press F1, then Enter) to show the old method of all controls together. |

Using Alsamixer =============== Alsamixer uses an ncurses interface, which may not display properly in an xterm. Start it by typing "alsamixer". Optional flags: alsamixer -h displays the available flags. alsamixer -e starts in "exact" mode. 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@suse.cz>.
