The key XF86AudioMicMute is unbounded

[Shuhao]

Not sure if this is the right component to file it in, but I have to start somewhere.

On certain machines there is a microphone mute key. This key, when tested with xev, is known as XF86AudioMicMute. It is not bound to any action by default as far as I can tell on a brand new install, even though it is relatively trivia to support it.

Workaround:

Create a new keyboard application shortcut to the application `amixer -D pulse sset Capture toggle`, or even fancier:

#!/bin/bash

amixer -D pulse sset Capture toggle | grep -q off

if [ $? = "1" ]; then
  notify-send "Mic on"
else
  notify-send "Mic off"
fi

However, this really should be addressed such that it is default, preferably with a better UI more consistent with the volume notification.

Status changed to 'Confirmed' because the bug affects multiple users.

Should work fine in Xubuntu 18.04 which uses xfce4-pulseaudio-plugin by default (support for the XF86AudioMicMute key was added in version 0.3.0).

Further to comment #3, belatedly closing issue as fixed.
