IOS 12 Crash - AudioToolbox

Hi,

This crash is only happening on iOS 12 devices, couldn't manage to reproduce. Occurring in both 2017.4 and 2018.4 LTS versions

Anyone else experiencing the same problem?

 

I have the same problem,some can help?

 

Hi,

Sadly I haven't managed to reproduce this exception myself and it's happening on a fairly large project so not sure which part causing this problem as well.

 

We're actually seeing something similar in our release game that is on 2018.4.7f1 @AurimasA

Is there any update on this issue, we get a lot of crash on iOS12 & iOS13.

 

Same here with Unity 2018.4.12f1, anything new?

 

I'm also seeing this issue, Unity 2019.2.17f1.

 

We are now seeing this all of a sudden on our 2018.4.13f1 builds as well. Anyone know a workaround?

 

Also confirmed in Unity 2019.2.5f1, on iOS 13.3

 

FYI: last 7 days crash report of my game.

 

Also confirmed in Unity 2019.1.1f1
iPad7,5 iPhone OS 12.3.1 (16F203)
iPad7,5 iPhone OS 12.4.1 (16G102)
iPad6,11 iPhone OS 12.4.1 (16G102)
iPad4,4 iPhone OS 12.4.4 (16G140)

All the crash logs have the same thing:
Exception Type: EXC_BAD_ACCESS (SIGSEGV)

Does anyone know how to reproduce this issue?

 

Does that have anything to do with this?

I can reproduce this crash, finally.
I'm using Google AdMob in my game. When the interstitial is showing, let try to make a call to your phone, the crash sometimes happens.

Search around on the internet, we should listen to the audio interruption event and pause the audio, then resume it when the interruption is end.

Here is how I fixed it:

Code (CSharp):

1. // somewhere in your app initialization
2. [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleInterruptionChangeToState:) name:AVAudioSessionInterruptionNotification object:nil];

Handle interruption events:

Code (CSharp):

1. - (void)handleInterruptionChangeToState:(NSNotification *)notification {
2.     NSDictionary *interuptionDict = notification.userInfo;
3.     NSInteger interuptionType = [[interuptionDict valueForKey:AVAudioSessionInterruptionTypeKey] integerValue];
4.  
5.     if (interuptionType == AVAudioSessionInterruptionTypeBegan){
6.         NSLog(@"AVAudioSessionInterruptionTypeBegan");
7.         UnitySetAudioSessionActive(false);
8.         _pausedByInterruption = YES;
9.     }
10.     else if (interuptionType == AVAudioSessionInterruptionTypeEnded){
11.         NSLog(@"AVAudioSessionInterruptionTypeEnded");
12.         if (_pausedByInterruption)
13.         {
14.             UnitySetAudioSessionActive(true);
15.             _pausedByInterruption = NO;
16.         }
17.     }
18. }

Don't forget to clean up:

Code (CSharp):

1. - (void)dealloc {
2.     [[NSNotificationCenter defaultCenter] removeObserver:self name:AVAudioSessionInterruptionNotification object:nil];
3. }

Updated: Let make a video call via Face Time, game crashed immediately, not showing an ad.

Hope this might help.

I am also having the exact same issue on latest Unity 2018.4.25 LTS.

Same here, reported by firebase. All crashes occurred on iOS 13 (it might be a coincidence though)

Still having the issue in Unity 2018.4.26 LTS.
It is affecting iOS users 13 for me.

Any work around anyone?

 

Same with Unity 2019.4.5f1

 

Still having the issue in Unity 2018.4.29 LTS.
It is affecting iOS 13 and 14.

 

Does anyone know how to reproduce? or Fix this?

 

I spent two days figuring it out. It's a bug in iOS's CoreAudio. Whether you're using fmod or wwise, this crash affects you. Long story short, audio engines try to stop audio output in the AVAudioSession's interruption callback. For example, wwise calls the AudioComponentInstanceDispose function in the interruption callback which makes AURemoteIO::~AURemoteIO to be called. However, in AVAudioSession notify thread, the InterruptionListener function was trying to access AURemoteIO::Stop(). The mutex in the InterruptionListener function is not well designed to handle such a condition.

If you can read Chinese, you can find my analysis of this crash in detail at https://zhuanlan.zhihu.com/p/370791950
