I have a problem that is is probably easily done with a mixer, but I can't afford one, especially with a podcast that doesn't bring any financial benefit to my wallet and was wondering if anyone can help. I've followed what has to be a dozen different tutorials trying to use Soundflower, Rogue Amoeba's Linein, OSX's aggregate audio devices, or any combination of them to route my system audio into Skype and into it's own track in Audacity. The goal is to be able to play audio into the show so the other hosts hear it, and to have it as its own track when we record as we double-end our recordings.

I have it working with Audacity using Soundflower and Aggregates in OSX, but Skype only hears my microphone. I think it's because Skype is only looking at the first channel or the first two channels. Is that right? Is there another free/inexpensive solution to get this to work? I do have an older Mac and a PC I could use to add to the audio chain if needed, I'm just not sure how to get it all working together.
