Andrew, while this is not an RTP stream, I have been able to software
mix the output of the Line Out back into RAT. I use it very frequently
for audio test situations where somebody needs to check their audio if
I am already gone for the night. I leave Amarok running in the
background playing my playlist and I set RAT to use the "mix" input.
This works perfectly with Slackware 13 and KDE4.
