So if you want to report applications that are using a microphone, you end up showing applications like PuseEffects that create a monitor sink. Those applications can use a microphone but in most cases don't, because PulseEffects is mostly used to apply effects to output streams (but need to record those streams effectively).

What matters is what libpulse offers, and it seems to me that we can check whether a sink is a monitor (https://freedesktop.org/software/pulseaudio/doxygen/structpa__source__info.html#a5e304b796ce71c7fa54e5a88f3333630). One would need to add a method isMonitor to Sink that reads this information and then we can not show the indicator when it's a monitor
  
  
  I'm afraid that application that really use a microphone, create a monitor sink.
