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

iOS

-

-

Priority: 2Necessary for shipping a final release

-

Severity: 2No workaround

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.

    @Firtina

    I have posted a response on the existing forum as I feel that it is a related yet separate matter to this one.

    Thanks

    @REBELINCONTROL yes it ( specifically: some types of audio not loading for older ios 10 devices ) has been fixed in the 5.5 release and in patches for it. This has also been confirmed by our QA. If you are continuing to have problems please upload a repro project as a new case; it could be a different issue.

    Can anyone confirm 5.5 or any of its subsequent patches contain the fix? I upgraded after releasing an update in 5.3.x and the issue is occurring again. I've tried 5.5.0f3 and 5.5.0p2. Has anybody actually tried and tested 5.5 for this?

    Thanks

    Looks like it may have been missed from the release notes, I will be notifying the team to get it added in there after confirming myself that it's in

    It should have been fixed in 5.5 as well as the latest patches for 5.3 and 5.4

    @FIRTINA
    Since I can't find a mention of this fix in the newly released 5.5.0f3 public release, is it safe to assume that the issue is already fixed in that release? Or should I wait for it to come in one of the 5.5 patches later?

    @GRIT When a bug is marked as "Fixed in Unity 5.3.8" it means it is expected to be in that version, and any version that will be released after it. So in this case, that includes 5.4.4, 5.5.x, 5.6.x, and so on.

    That does not mean it cannot land before! For example in this case; the fix has just arrived in Patch 5.4.3p1 - out now! For 5.3, 5.3.7p2 is the next patch.

    @MATTHEWDOMINEY We do not provide exact dates for patches (various reasons) but we try to keep a consistent schedule. There is a history of the ones that have been released: https://unity3d.com/unity/qa/patch-releases .

    You can find more information about patch releases on these posts: https://blogs.unity3d.com/2015/09/16/unity-patch-release-plan/ and https://blogs.unity3d.com/2016/03/15/maintaining-a-stable-version-of-unity-while-keeping-up-the-pace-of-innovation/

    There will be more blog posts regarding patch releases which should help to clarify things further.
