I’m also stuck with the issue of the Scarlett not showing in Audio Connections.
Original Issue
Cubase Pro 14.0.20 Build 240 for Apple Silicon
macOS Sonoma 14.3
Originally, the Scarlett 2i2 showed up in Cubase and I could record and play back. I then disconnected my device and switched Cubase to use the Built-In audio. Now, when I re-connect the Scarlett, it doesn’t show in Cubase. I’ve tried restarting the mac and unplugging the device, but no change. I can, however, use the Scarlett in all other applications (e.g. Spotify, Voice Memos, Garage Band), so it seems to be a Cubase issue.
Is there some way to reset the Cubase audio device settings to defaults? Maybe I messed something up when I selected the built-in device.
(Edit) Found a solution for me:
Studio > Studio Setup
Audio System > ASIO Driver > Change to Scarlett 2i2
Return to Studio > Audio Connections > Now I can select the device again
