Hello, my app crashed on the new MacOS12.x system, it works well on MacOS 11 BigSur.
I'm developing an audio app on MacOS using AudioUnit, it sometime crashed when i switch devices. the relevant api is:
AudioUnitSetProperty(audio_unit, kAudioOutputUnitProperty_CurrentDevice, kAudioUnitScope_Global, kAudioUnitOutputBus, &rnd_id, sizeof(rnd_id));
it troubles me for month, i can't find the reason or any useful info, any help will be appreciate.
the crash log is:
