Hey guys...I'm having a problem when it comes to the audio part of this game. Recently bought a playtronics Audio headset(a645) to communicate with members online(Ventrillo). I believe I think I did everything correctly when it comes to my PC(Vista) but I can't talk to fellow gamers. I can hear them but cant talk to them. I blow into the mic and can hear feedback but they cant hear me. I called playtronics and they told me it was probably the game itself...Under the GRAW 2 audio section, i dont show that im connected using this headset(Im not using USB...I can, but I'm not). Any help would be greatly appreciated..Thanks

Is ventrilo set up correctly?
Did you give your Microphone the 20dB gain?
How is the set-up in your config-screen (I'm on XP so I cannot help you the whole length)
If you can hear yourself that should mean that your microphone is connected and recorded by your PC, so the settings in Ventrilo should be worng. GRAW has nothing to do with that as it doesn't support in-game VOIP thats why you use Ventrilo....or in my case Teamspeak
