Hello there, I have bought a Logitech USB Microphone with a headset to talk with my fellow mates on Ventrilo, I tried going to sound in the System Preferences and put it on the Logitech USB on both input and output and even in the Setup bar of the Ventrilo Program I have tried it and it didn't quite function, not working at all. I am using the P-T-T and using the Built-in microphone but I don't like it and I would like to have some assistance in-getting this microphone work.
