Voice Chat Bug - Timeout

Hello I have a Problem with my ingame Voice,

every Game works fine with the Voice Activation, Steam detects the right audio
and in my TS³ everyone can hear me fine
but whenever i try to speak i am getting timed out and i have to reconnect

I am Using Virtual Audio Cable maybe this is the Problem?
I have tried to use the Direct Microphone Input wich doesnt work either,
there are more people with Problem…

I am using the Mad Catz - F.R.E.Q. 7
and I am running on Windows 7

Maybe if someone has a Solution that would be great!
