I have a rather strange issue: Muting the microphone doesn't actually mute it.
In the Microphone Settings panel I see it as being muted (graphically), my keyboard button that mutes it also lights up, however it still picks up sounds.
I'm on a laptop with an internal Realtek HD Audio soundcard and latest drivers running on Windows 8.1.
Any clue why Windows thinks it's muted and how to actually mute it?
Disabling it from the sound panel will work, but that's a bit extreme.
