Issue with iOS

[HereafterMills]

Hi,

So iv been trying to debug this the last few weeks. On iOS, connecting to voice and talking works great. BUT open any new map, even the menu map, 2-7 seconds later, the app crashes.

None of this happens if i never connect to voice.

Any hints as to what might be causing this?

Adding the logs folder in the agora settings to ProjectLogsDir>voice.log also doesnt save any file on ios. When i retrieve the container using xcode, it doesnt show me this logs file. I've tried a whole bunch of folder combinations to no avail. Any help with this would be nice, as it would help us identify the issue.

I think the issue is with leaving the voice channel.

@WinterPu some help please

You could build an iOS app and select [Debug - Attach to the Process] to trace the logs. I suspect that you may be triggering a garbage collection or neglecting to perform certain operations on the game's main thread. However, I'm not sure. You could give it a try.

@WinterPu I had managed to fix this in another app, but getting the smae issue in a new app. THe issue previously was that i was setting the outer for the RTCEngine and EventHandler as the player controller - which of course is destroyed once we start a new map.

Now im setting the outer as the game instance, but crash still occurs.

@WinterPu These are the last logs generated before the crash:

Like i said, this occurs on starting any new map (connecting to a channel the second time - whether its the same channel or a different one).

I suspect the AudioMixerPlatformInterface Timeout [ 5 Seconds] waiting for h/w. InstanceID=1 is what is causing the crash, but it always happens within 15 seconds and the timeout is 5 seconds, with the warning coming in 3 times. At times, it happens before 15 seconds as well

In the first map, the voice works fine btw.

You could try sth like this: AgoraUERtcEngine::Get()->setAudioScenario(agora::rtc::AUDIO_SCENARIO_TYPE::AUDIO_SCENARIO_GAME_STREAMING);

Or wait for the 4.5.0 https://github.com/AgoraIO-Extensions/Agora-Unreal-RTC-SDK/tree/release/4.5.0

Like this?

Also, should i just Use 4.5.0 now?

[WinterPu]

Yeah, we are still testing it. It is coming soon.
