Hi Im using the new TS3 beta for Arma2 with the ACRE mod. (google it)
When I connect to a server I cant use Push to Talk, the blue light doesnt flash when I push the hotkey. I used every single key on my keyboard and mouse, no one works.
On the old TS3 version, my PTT works fine.

I am using Vista x64 and the NVidia HD Audio SoundCard.
