Using live audio streaming software

[Trogdor2010]

Hello.

I am trying to figure out how to select an audio output option for PC gaming streaming. Xsplit is having a problem starting up, so I am using adobe flash media encoder for streaming, which has a lot of problems, but is functional for streaming. Whenever I select audio settings on either the program or with VH capture, it only selects microphone outputs, which I want to have both audio from my game and microphone. I tried audacity and I can't figure out how to use it. Any programs that can work with audio streaming?
