No input signal in Reaper on Mac (solved)

Hey! Recently, I switched from a Windows PC to a Macbook Pro M1. My QC is going through the USB hub of my new Samsung ViewFinity6 Monitor. I can select the Device in Reaper, which is called “Quad Cortex USB 2.0 Output” and playback is working fine. But however, I get no input signal and therefore I cannot record anything. Input is of course USB Output 3 (from grid). What am I missing? Is it the USB hub on the monitor? Am I missing some settings on my Mac? No DI signal as well. Thank you!

Ok, got it! Reaper was not allowed to use microphone in the mac settings. And somehow this also affected the QC input signal :slight_smile:
