The main issue here is sound server (pulse audio). You want it to know
about the microphone is muted. This is basically how it is done in
Windows (via special program by Lenovo .. it doesn't work on a Windows
default install).
This separate userspace process would learn from the pulse audio sound
server if the microphone is muted .. if so then turn on the microphone
light as well (so the user has indication the microphone is muted).
My longer term plan with this is to have a key defined for this. Add
support to Gnome Volume Settings. It will then catch the key, mute at
the Pulse Audio level & give the users some on screen notification as
well.
