Sound problem in coop mode!!!

[glm]

I and my friend play coop in PC, and the second PC has really noisy sound during play, I think those noise come from the Micphone, but the second PC still has the Micphone noise after we pull out both our Mic from our PC.

We don't have this problem in SP game for both of our PC.

Is there a way to disable the Micphone? Just dont receive voice from other.

Thanks
