Headphones / Headsets / Microphones

[NIIRU]

Hi all

I recently received my replacement G35(ear-pads where worn out). I had a problem with the first one I had. When using the mic(unmuting/bringing it down) it muted the front center speaker in surround sound mode. But now with my new one, it mutes the center left and right speakers. Muting and unmuting the mic solves the problem, but it takes a couple of tries until it fixes.

Searching the forum, I have seen a few that where having the same or similar problem that I am experiencing.

Is this normal? And is there a way to solve it?
