I have my mic, but when I press F12, I don't hear the beep, and nobody hears me talk. I have no idea how to set up VOX, as whenever I previously used it, it worked.
How ironic your button avatard is...
My mic works, and the keys are mapped, but there still is no beep. <EDIT> There's no beep, but people can hear me now... problem solved. It turns out my mic volume was almost all the way down.
