polybar-mic-volume

Polybar module that displays the volume of a given input device using PulseAudio pacmd and controls it using pactl.

Usage

To use this module, put the following module in your Polybar config, substituting MICROPHONE_NAME with the name or index of the device you want to display, and substituting PATH_TO_SCRIPT with the path to the mic-volume.sh script.

If you don't include MICROPHONE_NAME the default input device will be used instead.

[module/mic-volume]
type = custom/script
interval = 1
format = Mic: <label>
exec = bash PATH_TO_SCRIPT show-vol MICROPHONE_NAME

; Control actions (using pactl)
click-left = bash PATH_TO_SCRIPT mute-vol MICROPHONE_NAME
scroll-up = bash PATH_TO_SCRIPT inc-vol MICROPHONE_NAME
scroll-down = bash PATH_TO_SCRIPT dec-vol MICROPHONE_NAME

For example:

[module/mic-volume]
type = custom/script
interval = 1
format = Mic:<label>
exec = bash ~/.config/polybar/mic-volume/mic-volume.sh show-vol 'alsa_input.usb-Samson_Technologies_Samson_Meteor_Mic-00.analog-stereo'

; Control actions (using pactl)
; Example supplying the name of the source
click-left = bash ~/.config/polybar/mic-volume/mic-volume.sh mute-vol 'alsa_input.usb-Samson_Technologies_Samson_Meteor_Mic-00.analog-stereo'
; Example supplying the index of the source
scroll-up = bash ~/.config/polybar/mic-volume/mic-volume.sh inc-vol 2
; Example leaving the MICROPHONE_NAME blank and using the default source
scroll-down = bash ~/.config/polybar/mic-volume/mic-volume.sh dec-vol

NB:

The and index of the source can be found by running pacmd list-sources. Ignore the arrow brackets when using the name.
