MicRecord Demo AudioUnitRender failed on MacOS

[turnercore]

Which demo project is affected:
godot-demo-projects/godot-audio-demo/audio/mic_record

OS/device including version:
Apple M1 Pro 16GB
Ventura 13.2.1

Issue description:
When loading the demo project get multiple errors a second, recording doesn't work.
Errors are all this:
E 0:00:03:0139 input_callback: AudioUnitRender failed, code: -10863
<C++ Source> drivers/coreaudio/audio_driver_coreaudio.cpp:238 @ input_callback()

It has to do something with the AudioStreamMicrophone because if I remove that from the AudioStreamRecord node then the errors stop. Also if I turn the AudioStreamRecord node to not playing the errors stop. Tried manually creating a new mic resource and attaching that, got errors just the same. Also, the audio doesn't record and playback in addition to the errors.

• Duplicate of macOS audio recording error: input_callback: AudioUnitRender failed, code: -10863 godot#58180 (this is an engine issue).

Recording should work if you change Mix rate to 48000 Hz in the demo, or configure macOS to use 44100 Hz sample rate.

Thanks! That worked, but just for anyone that finds that after you need to change the Mix rate to 48000Hz in the Project Settings, not the script. (Although I also changed the default in the script as well).

Does recording work if you change mix rate to 48000 Hz in the Project Settings, but keep the Mix rate option in the demo to its default 44100 Hz?

I'm working on a PR to override the mix rate on macOS, so that audio recording should work out of the box. I wonder if I actually have to change the saved mix rate, or just the project setting.
