Mute function in the media section of the hid_app (USB Remote)

[ajrohr]

Description of the feature you're suggesting.

I would like to have a mute function in the media section of the USB Remote app. As far as I know, the back button in this section does not have a function. Adding a way to mute the computer when the back button is pressed would be invaluable. Thank you very much for your consideration!

This would extend the existing functionality of the app.

Anything else?
