What can I do to make Jack Audio recognize my Xone K2 audio interface?

Hi guys.

Finally after a long time trying to use Jack Router, I think I got it, of course "with a little help from my friends" as the song says.
Everything is working perfect in my Jack Router - Traktor - Ableton setup. Also the cue monitors (headphones) in Traktor and Ableton and the monitor speakers are really ok.
You were right Uwe, it was necessary to check the Asio4all configuration.

Thanks to everybody..

Hi Sûlherokhh.

I think that these are just speculations about an update of the K2 mixer. This hardware is about 10 years old since its release and many people are waiting for a new version.
