Ventrilo 3.0.4 -

I have just upgraded to Snow Leopard. I am logged into Ventrilo 3.0.4 and trying to speak to group w/ USB Logitech headset (w/mic). It tells me to change Universal Access Settings, which I have, but my group still can't hear me. They can hear a computer generated voice, if i type in the chat box. I need to speak and they hear. I don't care if it's a computer voice or mine, but I need my hands to be free! Thanks in advance for your help!
