Sound playing from wrong directions

[Beandip]

In Dayz Epoch all my sounds are reversed. As in if something happens on my left then I hear it on the right, and behind me is heard in front of me. I have tried normal Arma 2 OA and I dont have this problem. I use a pair of Plantronics Gamecom Commander headphones. What could be the problem and how do I fix it? I have tried changing the amount of sound samples in the ingame audio menu. This is a gamebreaking bug as I cant figure out whats going on at all.

Put headphones on wrong way round:)

Theyre on the right way. And I found the issue but no idea how to fix it. Teamspeak causes the problem when I play DayZ
