Reply to Using Traktor Kontrol S4 for LiveStream / UStream

Hello mates! I'm new there as you can see

I want to make a (online) Stream with my Traktor Kontrol S4, so i'm trying this steps:
Put the S4 on with usb to the computer, and put RCA from input of S4 into output of computer (microphone), but when I watch my Stream (in website) I listen the CUE channels from my controller, so, what should I do?

Thanks in advance, and sorry for the bad english xd
