Public bug reported:
Mic mute hotkey (Fn+F4)on Dell Latitude 7370 does not work. It generates
a correct keycode but this is not translated into 'action'. Mic mute can
be activated in software by ticking the mute checkbox, and this
correctly activates the mic mute key's LED.
Also present in Zesty daily ISO.
