Xone K2 sound issue


When I connect my Xone K2, the device is recognised but the sound output is very low, next to unaudible. I do get sound out of 1 and 2 that can drive my headphones. But even if I take an aux cable out of the headphone port it is very quiet on my Hi-Fi , similar levels to what I’m gettin out of the rear rca ports.

The Xone k2 works without problems when connected to my Mac.

Can someone help me fix this?
