I'm just about to pull my hair out. I cannot seem to get voice or even chat to work in multiplayer mode. In FSX I log into multiplayer(Gamespy)and enter one of the numerous sessions (with green voice icon) but when I set up my flight I always get the red no voice icon. I've gone through and set up my mic (headset mic) and still no luck. When I launch the session and get in the game no ATC functions work...Am I missing something? I've searched the internet with no luck. I forwarded port 3783 on my router as suggested on a forum... still no luck. Its like the voice function isn't even installed.Please help before I'm bald.Tbrickey

Thanks Geoff for the reply. Everything checks out. Port range is 6112 - 6122, 3.6 VC and voice communication is checked.I have port 6112 - 6122 forwarded in my router... I use my headset mic in other multiplayer games (i.e. Steam- Day of Defeat) and it works perfectly.Any suggestions??tbrickey

I'm having the same problem. I tested mine and it still won't work.

Here we are, three years later and now I'm having this problem after having sucessfully been using a USB headset on a WindowsXP/FSX Acelleration.Since upgrading to my new computer with Windows 7, my headset simply doesn't work in multiplayer. Hope someone will share how they get theirs to work!
