Dear Maintainer,
* What led up to the situation?
I tested the "default" and "optional" microphone
* What was the outcome of this action?
Default microphone behavior is mirror of desktop audio. And optional microphone is not mirror of desktop audio.
* What outcome did you expect instead?
Default microphone behavior should be audio datas of physical world.
