Over Mic in Second Life?

[AnonymousMJ]

I know there is some way to do this, but I need some help in finding the solution. I am trying to stream whatever music I am listening to over my mic in Second Life, while still being able to listen to it. All without my actual microphone playing what I say over mic. Only playing the streaming music in other words, without interruption. How would I go about doing this?

I've seen this done by an old friend of mine. She used to do it every once in a while, and I don't know how she did.
