radio broadcasting with traktor

hello,
my latest need is to broadcast my sets while im playin at the bar.
my first problem is that im mixing external mode with an X1 therefore traktor's integrated broadcasting system is useless (for me).
i've just foung this great utility calles ''butt'' (broadcast using this tool) that can broadcast taking signal from audio devices. my only issue is that i cant get it to see my audio 2 dj!

has anyone used this program?
any ideas for other utilization of this project?

Traktor's internal broadcasting tool os pretty useless regardless of your setup. I use Nicecast which is Mac only and Mixlr.

so i've tried mixlr and it cannot see my a2dj (?)
what setup r u using?

edit: well, i can select a2dj only as audio outpout, not as an audio source!
