DAWs not receiving input from interfaces
I have an M1 Mac Mini and an M1 MacBook Air. I have used the Mini previously for some home recording without issues (using, alternately, Audient iD4 and Solid State Logic SSL 2 interfaces), using a variety of apps including Tracktion Waveform 12, GarageBand, and Ableton Live.
However, something in macOS seems to have broken the connection between audio inputs and the apps.
The interfaces are working fine - I tested them on an older Intel MacBook Pro.
In System Settings -> Sound, when I set the audio input to the external interface, I can see the level meter moving properly. I can also record into QuickTime Player using ‘New Audio Recording’ just fine, so it seems the OS is receiving audio at the system level.
However, whenever I try to create a new track in any DAW, no audio is being passed through, even though all the audio settings are correct.
I have swapped cables and ports to try to rule that out; tried USB-A and Thunderbolt ports on the Mini, tried connecting through the hub on my LG 5K, nothing changes.
This appears to be a system-level bug. Any ideas?
