Working Solution for streaming audio

I was trying to find a way to stream voice chat from within world to a shoutcast server. I needed to record what I said as well as what other people would say. To do this, I needed to run an alt avatar on another computer so that both sides of the conversation can be heard. In addition, the software that I was using (SimpleCast) to record and stream audio to the server wasn’t capable of recording “what i hear” on some of my computers. I tried out 3 computers until I found one that worked. I believe that this is a feature on the soundcard itself that the others do not provide. Now my only concern is regarding how long my avatar may remain in-world without going AFK and eventually logging out
