[iOS] Audio with 'Streaming' Load Type does not play on some devices running iOS 10

iOS

-

If an Audio Clip has its Load Type set to 'Streaming' it does not play on some older devices running iOS 10.

Steps to reproduce:
1) Open the attached project (streamingTest_832578).
2) Build for iOS.
3) Run on a device via Xcode.
4) When the app launches, press any of the UI buttons on the screen.

A sound should be played, however it does not. An error message is displayed in the Xcode's console:
Error: Cannot create FMOD::Sound instance for resource resources.resource, (An error occured that wasn't supposed to. Contact support. )

It does not occur if the Load Type is set to 'Decompress On Load' or 'Compressed In Memory'. This only happens with iOS 10.
It seems that only older devices (like iPhone 5, iPad 4) are affected.

Reproduced on:
5.5.0b4, 5.4.1p1, 5.3.6p5, 5.3.5p6

Did not reproduce:
5.2.4f1

I was able to reproduce it on iPhone 5, running iOS 10.0.1
Devices running iOS 10 that did not reproduce:
iPhone 6, iPhone 6 Plus, iPad Mini 2, iPhone SE.
Other users reported that this is also reproducible on iPad 4th gen and iPhone 5C.

    I finished my game (using 5.3.6f1) and went camping to take a break before releasing it. Came back and this bug bit me when I upgraded to iOS 10.

    So maybe as a workaround, avoid camping...I guess.

    Still an issue in 5.4.2f1. I am using the default universal build settings, which includes armv7 and arm64, testing on an iPad 4 running iOS 10.0.2.

    I have found that this only happens when you build armv7 architecture and run it on a device that is capable of running arm64. For example if you compile armv7 and run on an iPhone 6. When you build a Universal app with both architectures, streaming seems to work as expected on all devices.

    I have verified this is still an issue with 5.3.6p7, and am using IL2CPP scripting backend.

    I have verified that this IS still an issue with version 5.4.1p4.

    Can someone verify that this is still an issue in the patch build 5.4.1p4? Nothing in the patch notes implies that it has been fixed.

    Maybe, the issue occurs on 32 bit architecture CPU (less than Apple A7).
