Hello, I've been looking around for help but I'm not sure what to do.

What I want to be able to stream my desktop using the audio from my computer (NOT my built-in Mic) .  I'm using a late-2009 iMac with OS10.6, and in Audio Midi setup, I can only add an "Aggregate Device". The attachment shows how it's set up but it doesn't work. The stream doesn't pick up audio from the computer. "AudioRedirector" is for Procaster is can be ignored here.

I use CamTwist and Flash Media Live Encoder for streaming. I sometimes use Procaster but the audio issue isn't with these programs I dont think.
