iOS 13.4 is throwing OSStatus error -66681 while playing AAC 5.1 channel

I am trying to play the content which contains aac-5.1 channel 6 audio.

But we are getting -66681 error from the OS. The content is working in lower version of iOS.


Please help me how to solve this issue.


I found one online source to check Audio playback :
https://www2.iis.fraunhofer.de/AAC/multichannel.html

Contents are playing in iOS 12, but in iOS 13.4 i am unable to play the audio.

I saw the log there are some error i can see which i am mentioning below :

/AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/CoreAudioServices/CoreAudio
Services-1104.80/
CoreAudioUtility/Source/CADSP/AUPublic/AUBase/AUBase.cpp:1389 ioData.mNumberBuffers=6, 
output->GetStreamFormat().NumberChannelStreams()=2; kAudio_ParamError

Yes, we've some problems.
And this happen only on some iPhone devices (ex, iPhone XS).

It's very strange that Apple does not pay more attention to this problem.
If you think this is a problem in the OS, please file a new bug.
