Add support for mute button on headset

[agauvrit-tis]

Context On some headsets, a mute button is present on the side of the headset, this mutes microphone in voice softwares.

Describe the feature you have in mind Muting microphone using a physical button should mute microphone in Mumble-desktop. I have no idea how the mute event is catched, if it's software-sided or driver-sided.

Describe alternatives you've considered None

Additional context

• This behavior is catched by several other softwares, such as Microsoft Teams or TeamSpeak for instance, it's really handy.
• Device with that behavior : Plantronics Savi 8200 Office

I actually have seen no software so far that indicated the mute-state of my headset (and I used TeamSpeak) in the UI :thinking:

Looking at this again I think that implementing this would require specific code for each and every headset that provides such functionality.

I think normally the driver of that headset is responsible for setting the mute-status in the OS. And that's decoupled from being muted in Mumble. I thought we already had an issue for mirroring the OS's mute-status but I can't seem to find it atm...

Could we please get this functionality? I really don't know how this works technically, however I'm using a logitech H820 with mumble for work stuff, and having the physical mute button being in sync with zoom is just very comfortable.

I mean, muting works on this one either ways, it's just not reflected in the application if there's no app support. I know that some Bose stuff that a friend is using, that does require app support for the mute button to work.

So, if this is possible, I would love to have such a feature.
