Plutonium

It works now, I dont know why and how but there we go

So I downloaded Plutonium. Installed it and followed the tutorials. I can load into games and everything works apart from my mic. My microphone only works when I have the game open. I.e. when I close the game the microphone isnt working on any other apps. Even on settings the mic isnt getting picked up. I boot up the game and it suddenly works. Currently in a state where to get my microphone to work I need to have BO2 open. Whats going on?
