Hi Guys,
I got the traktor A6,connected to my technics sl1200,I'm using the traktor scratch pro software.I got my traktor S2 as my internal mixer. Everything works grate , except two things.

1.I can't hear the track I want to clue in my headphones.only time I can hear a track is when I put the channel up on the S2,and my headphones are plugged into the A6. Then I can hear the track on the headphones.

2.Then main level button won't funtion on the S2 but if I click it on the software using the mouse, I can change the levels.

Please can someone help me please, I've tried everything and I'm just dieing to mix.
Thanks for your time , any advise would be appreciated.
Regards.
