Can't use voice chat?

For some reason my voice chat isn't working...Everything is plugged in correctly, on the right settings, and I'm pressing the right button. I don't know whats wrong >.<?

I think they said voice chat isn't enabled yet

How come I've heard people talking then?

Voice chat should be on, in, and working.

The bulk of the heavy lifting with regards to capturing and encoding voice from the microphone is handled by steam, not by MNC. So my first question would be: does you mic work in other Steam games?

Also, maybe a dumb question, but do you know you have to hold the button down the whole time you're talking and not just push it once to start talking?

Yes, it works on other steam games, and yea I know you have to hold it
