I'm seeing the same issue. According to below thread, current sample needs to be updated a lot.. https://developer.apple.com/forums/thread/735371

I'm seeing the same error, only on iOS16. [AudioConverter] CompositeAudioConverter.cpp:1239 Input data proc returned inconsistent 1 packets for 1884 bytes; at 4 bytes per packet, that is actually 471 packets There are too many same error messages and difficult to debug..
