How to use DDJ s1 audio for livestream

Hi Guys, 

would broadcast first the audio of my set. 

I haven't found useful links on the web.

So I've tried differents configurations : 1 ==> Master 2 (AUX) linked to laptop mic in ==> No sound seems to be captured

                                                                     2 ==> Master 1(XLR) linked to laptop mic in ==> No sound seems to be captured 

Anyone has an idea ? Maybe I must configure mic in out with DDJ S1 Line ??

Here's my config : Win 8 64 bits using 1.6.3 Serato Dj with DDj S1

P.S. : Have a look on attachements bellow (sorry they haven't been very well resized ^^ )
