I was wondering if anyone else has this problem.
When I am on Hardline sometime the capability to key up my mic in team speaks stops.  I still can hear everything I just can not talk.
So far the only way I can fix the problem is to sign of of team speak and origin and restart it all.
Any similar problems or solutions?

I haven't run into that issue. But there are some exceptionally intelligent computer guru's in BK , I'm sure someone will post an answer.

Maybe you have something in your game that is intercepting your mic button in game.

When I say this I mean the key you use to use your mic might be used in game with something else and wont work.

I'm not that smart with computers so that's all I could think of.

I don't even know if what I said is possible lol
