PortAudio plugin on Apple Silicon Mac

Not sure what the issue stems from. Opening a microphone source gives me:

** (Membrane.CallbackError) Error returned from Membrane.PortAudio.Source.handle_prepared_to_playing:

I'm on the older ones. Pre-API change. Haven't had time to get familiar with the API changes yet 🙂 Anyway, this only failed on the Mac and works fine on my Linux box which was annoying.
