A friend of mine just bought a brand new Sennheiser pc160.
Now we're in ventrilo, and when he talks, we can hear all the sounds from counterstrike as well.
Which, as you can image, is pretty damn annoying.

Now we tried to change some stuff in the sound settings and stuff, but it didn't work.
Has anybody had the same problem? how can you solve this?

plz help me out

Do you have the same problem with your friend is playing another game ?
If not so the problem is in his CS settings.
I don't know any command to solve the problem but it should be easy to fix.

Try changing the codec in ventrilo. Even better, use TeamSpeak :D

check ur senheiser driver,what o.s u use?
and what is the config for pc?
check ventrilo codec too but i dont think its that
