Was this running on a real device or emulator?

Was it connected to a debugger at the time it crashed? I've only ever seen this when running the app on a device connected to a debugger, such as what is described in #1195

If it is reproducible, then why not just put a breakpoint on ax::AudioEngine::end() and trace the execution of the code from there?

kiranb47 · 2023-05-25T06:17:34Z

Hey @rh101 The issue is not reproducible in any of our test devices. Crash logs are from Google Play live users.

aismann · 2023-05-25T06:37:16Z

The issue is not reproducible in any of our test devices. Crash logs are from Google Play live users.

Is this a sporadic issue (only some devices/users), right?
Or a general issue on all same devices?

rh101 · 2023-05-25T06:54:00Z

@kiranb47 Are you by any chance calling AudioEngine::end() anywhere in your own code?

For example, in the Cocos2d CPP template, there is this section in AppDelegate.cpp:

AppDelegate::~AppDelegate() 
{
    AudioEngine::end();
}

User don't needs to invoke AudioEngine::end, see this issue: #550

I just had an idea and tested it out, and managed to reproduce this issue consistently.

Load the app
Make or receive a phone call

This causes the audio section to throw an error, which closes the stream. Audio in the app no longer works, and eventually it will crash because of 2 different issues.

One would be something like Fail to play Sounds/AudioFile.mp3 cause by limited max instance of AudioEngine
OR
The other would be what is posted above by @kiranb47, which would generally happen when a user exits the app: terminating with uncaught exception of type al::backend_exception: Failed to stop stream: ErrorClosed

When I received a phone call, I saw this in logcat:

oboe_aaudio_error_thread_proc() was definitely called there, which closes the stream.

@halx99 This shouldn't be happening, right? I've never tested this scenario before, but this causes the same issue described in #1195

@halx99 Using OpenSL, everything is working fine, with no errors or crashes at all. Making and receiving phone calls resulted in this logcat output, which looks normal, with no errors:

@rh101 thanks for you test, merged

You're welcome. I hope that the issue @kiranb47 is having is related to this, and that this solution solves it too.

halx99 · 2023-05-25T09:17:37Z

refer to https://chromium.googlesource.com/external/github.com/google/oboe/+/refs/tags/1.5.0/docs/OpenSLESMigration.md#stream-disconnection, the oboe with aaudio backend support stream disconnect(require recreate stream after handphone call). that's why opensl no this issue, maybe openal-soft not handle properly.

rh101 · 2023-05-25T09:28:10Z

the oboe with aaudio backend support stream disconnect(require recreate stream after handphone call). that's why opensl no this issue, maybe openal-soft not handle properly.

Fair enough. Would it be beneficial to eventually re-enable OBOE in the future and add support for recreating the stream on any error conditions? Using OpenSL right now is the right move to prevent the crashes, but I'm not sure if anyone requires the extra functionality available with OBOE, so I can't comment on that.

halx99 · 2023-05-25T10:41:32Z

I think opensl is enough, but I also create a bugfix PR for openal-soft: kcat/openal-soft#848

kiranb47 · 2023-05-27T05:07:54Z

@halx99 @rh101 @aismann Issue is now resolved after i changed to OpenSL. Thank you for the PR.
