Problems with MIDI Keyboard after updating to 4.1

OK, maybe I miss something, but after updating to 4.1 I can’t “audition” Sounds. When recording on a staff (no matter which instrument) my Arturia Keylab MkII get’s recognized and Dorico records the data. But while writing and also while recording there is no sound at all. But playing back notes is working. So not a general Playback problem . When I open older Projects everything works just fine, so neither a problem with the Arturia. Do I miss some preferences???
