Hi, sorry for late answer. Here are the screenshots of Denon Asio driver setup and Denon DN-X1600 asio driver setup. The difference is that fist on shows on Scratch platter “waiting” and other “scratch disabled”.
Scratch used to work in older Traktor 32 bit version with Denon Asio driver. But now with 64 bit Traktor and drivers with none as it’s the topic here.

With both phono/input line “not supported” on audio setup tab.
Thank you
