No audio being seen or recorded by Audacity 3.2.1

I recently upgraded my audio interface to a MOTU 828x Thunderbolt. I also downloaded the latest Audacity 3.2.1. Unfortunately, this version of Audacity is not seeing any incoming audio to record, which never happened with my former USB interface.

Thanks for any tips you may have!

Try Transport > Rescan Audio Devices, then check your Audio Setup.

Also, you may need to check microphone permissions: Control access to the microphone on Mac - Apple Support
