I want to detect if the user turned off the Microphone on a Windows Store app on the fly. I know that it is possible because Audio Recorder uses it. But how?

**UPDATE**: I want to be notified by an event that the microphone was disabled.

Is there anything to do with this? <http://msdn.microsoft.com/en-us/library/windows/desktop/dd370810(v=vs.85).aspx>
