Allen & Heath Xone:K2 Midi Mixer with 4 channel audio not supported?

Hello there,

I’ve tried to run my USB Allen&Heath Xone:K2 DJ Mixer with 4 Audio Out Lines (2 for Headphone and 2 for Enviroment) at the Khadas vim… If i run lsusb only the Midi Interface is found, but i can’t get it working. Also i have been tried to compile drivers for midi and for sound on my own. Which drivers do i need to compile for the Mixer? Is there a Kernel Problem?

What is missing there in Ubuntu that it can’'t run out of the Box with the Mixxx DJing software, like in Ubuntu x64 or x86…
