amixer (Emacspeak User’s Manual

12.1 amixer

Provide an emacs front-end to amixer, the sound mixer in ALSA that is used to configure the audio device.

The main entry point is command emacspeak-audio-setup bound to C-e). When called for the first time, this command builds up a database of available controls on the default audio device. These control names are then available for completion in the minibuffer. Pick a desired control, e.g., "master playback volume", and this displays a prompt with the current value. Enter the new value and press <RETURN>. To reset all controls to their default values, Press C-j.
