Input shows 100% clipping white noise all the time, also output sounds garbled


I have never used Cubase 6.5 (on Mac OS 10.13) or really another DAW. I connected my Focusrite Scarlett 2i2 and set it up as shown below. But I get 100% clipping white noise from my inputs when I record, and an imported mp3 will sound distorted, too. That doesn’t happen when I switch audio devices to Apple internal sounds (I can hear the mp3 properly). Also, the inputs should be fine, nothing is connected and it works well with Audacity.

Where did my routing go wrong? I start off with the Jazz Ensemble producing preset.

Thank you very much!
