Can't set up audio input/output (Traktor 3 pro + pioneer djm 900)

[bloomee]

Hey everyone, I've been trying to config the settings to be able to stream on Twitch. Despite trying everything I've found online I have not come across the right setting to make it work.

This is my setup:
- Pioneer DJM 900 nexus
- Traktor x1 MK2
- Traktor PRO 3 (in external mode)
- Komplete audio 6

And the settings:

Any help will be much appreciated!!
