Plutonium

So i need help with a sound issue. When im in a discord call, the mic for the call and my bo2 zombies mic are connected. My friend hears the in game mic audio, as in my voice. Ive tried everything that i can find online and there's nothing that has helped. The record mic level in game controls my discord mic aswell. Meaning if i mute the record level in game, i also mute my self in call. Please someone help
