Turntable into S4 mk3 plays through Ableton but NOT Traktor!?

Turntable into S4 mk3 plays through Ableton but NOT Traktor!?

As the title says…

I have a turntable hooked up to my new S4 mk3. I can hear the audio through ableton but when I select ext in Traktor 3 there is absolutely nothing.

It must be a problem in the Traktor software.

Anyone else having problems routing audio into Traktor 3?

What exactly are you trying to do? DVS? Playing real vinyl through software for FX?
