I have been trying to figure this out for awhile. It seems to have only started since i upgraded to windows 7. Anytime i start vent and the game, my vent no longer works. It seems like it freezes up or something since the icon shows it is continuously talking. I have posted this in the vent forums a few months ago but no body answered.
I have tried unlocking the controls so only Vent was using CTRL. even did hands free so i didnt have to worry about that. Also ran everything as administrator, checked the bandwidth. I have tried nearly everything i can think of, even changed to Teamspeak and other forms of communication. But Arma2 seems to take away all types of talking, even in game i cant do it. I dont know where else to turn so i guess i am posting this here. Anyone know the answer?
