Hello, i dont know why. But i can´t Talk via VOIP anymore. I press B , get the Green Speaker Light. But nobody can hear me... I even Update the Mic Driver.... Any Suggestions? It worked Yesterday, plugged it out. Back in and guess... It didn´t work again ...

Did you check in " Sound" from the control panel . Go there see what the settings of it is might just have to slide it up 100% or maybe see if it is being seen.

Are you only having this problem ingame on bf2 or also TS3/Ventrilo?

"Are you only having this problem ingame on bf2 or also TS3/Ventrilo?"
If the answer is on TS3/Vent too, make sure you didn't hit the hardware switch that your mic might have.
Happens to me too; I have a little switch that can disable the microphone entirely (via hardware).
