I am having trouble with my mic, first is had some troubles getting it connected to my computer (it's a bluetooth headset, and my computer is 4 meters away from me)
so i fixed the connection problem by using an USB extension cable on the receiver

next problem is ingame, my VOX does not work so i have to push a button constantly. So if i have to do a fast report when all my fingers are occupied, i can't do it!
it would be handy if it was voice activated!

well I've helped fix several mics just by telling people to go to their start menu and type search for ..troubleshooter... then look for the audio devices and test your mic. This may not help in your case. As it might be specific to your microphone. But you can try, and also try to play with your settings in america's army voice settings and test yer mic there also.
