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:

Same here. Here's some similar problems:

When running on older iOS Simulator, error “Failed to start launchd_sim: could not bind to session, launchd_sim may have crashed or quit responding” (I asked)

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!

How can this still be an issue @Apple. Ever since Big Sur the backwards compatibility went to bits and pieces and required me to install Catalina on a different partition to test anything below below iOS 14. On top I can't run anything above 14.4 because of different issues. Its a mess.

Same story here. Simulators with iOS 12.2 crash and burn when initializing audio on

[AudioHAL_Client] HALB_IOBufferManager.cpp:226:GetIOBuffer: HALB_IOBufferManager::GetIOBuffer: the stream index is out of range

just like OP stated. I'm on Big Sur 11.6 and XCode 12.5.1

I downloaded the iOS 14.3 runtime and now it works. Not an acceptable solution and it's been 9 months since the OP. C'mon Apple, let's go.

Surprise, surprise! Yesterday I updated my macOS to Monterey Version 12.1. Today, with Xcode 13.1,

I can play audio in Simulators with iOS 12.4 as I described in this thread one year ago.

I suggest everybody to check if your problem is solved with macOS 12.1 as well.

Answer 21

teejayhh OP

Aug ’22

Its Aug 2022 and this is still an issue. Our app needs to support iOS 12/13 and we have no way of effectively testing our app. So I guess the only way apple expects us to work is to feature flag our app and remove all audio components on app start via a launch argument? If anyone from apple will ever look here they will tell you, to create an issue report on their feedback site. The issue with that is that no is ever looking there either. Time is on their side, unfortunately for us devs who need to deal with these issues it is giant waste of time.
