I can no longer run my app in the simulator with a version lower than iOS14.
I tried iOS12, iOS12.4, iOS13.7 and they all crash with the same error.

This only started since upgrading to Big Sur. Nothing has changed in my code base.

This is the code that crashes:
Code Block  //6.
    // Provide callback audio rendering function on the unit
    // Set input callback
    AURenderCallbackStruct callbackStruct;
    callbackStruct.inputProc = playbackCallback;
    callbackStruct.inputProcRefCon = self;
    status = AudioUnitSetProperty(_audioUnit,
kAudioUnitProperty_SetRenderCallback,
kAudioUnitScope_Input,
kOutputBus,
&callbackStruct,
sizeof(callbackStruct)
);
    NSAssert1(status == noErr, @"Error setting callback: %d", (int)status);
    //start audio
    AudioOutputUnitStart(_audioUnit);


The error "Thread 1: signal SIGABRT" occurs at the last line...
Code Block 
AudioOutputUnitStart(_audioUnit);


And the errors in the console are:

As I said, the only thing that's changed since it last worked is that I upgraded to Big Sur.

It runs fine in the iOS Simulator, but not in simulators with a lower iOS version.

The Audio Output of the Simulator is set to Internal Speakers.

Any help is much appreciated.

Hi,
I'm glad not to be the ony one with this issue.

I'm using AVAudioEngine from iOS 9 to iOS 14. Since Big Sur Update I can only use simuated devices with iOS 14. Elder stages of development don't work either since the Update. I do not experience the failure on real devices.

For my error stack I chose the same target as You( on iPhone 8 Plus simulator with iOS 11.4) and it seems to be pretty the same:

No crash here but application grinds to a halt, using AVAudioSession and AVAudioPlayer.

App execution on iOS 12, 13 simulators immediately logs:

After the 15 second timeout the app continues running until the next call to AVAudioSession or AVAudioPlayer.

On iOS 14, everything is fine. I hope this does not occur on real devices but could not test that.

Same symptoms as for SmartPTT and Wizfinger: playing audio freezes the app, same Console errors, happens on iOS < 14 on Simulator. I don't have test devices with older iOS, but some logging code I added to the app is reporting similar problems in live versions in the field.

This complaint shows up (with variants) all over the place. I am able to reproduce it in a from-scratch Xcode project, so I will be posting my code on Stackoverflow and asking DTS. I hope to have something more helpful to add here besides "Me too."

This has been acknowledged as a known issue by the Media Team in July 2020, more than 9 months ago (see link below)! No idea why this is still not fixed. Just because its only happening on the simulator doesn't mean this is not a serious issue. I don't have devices lying around with all previous iOS versions. Apple please take this seriously!
