still got this error in Unity5.3.5f1

I believe this issue, post 5.3 fix, this error can pop up based on the path of the file you're trying to load. I got this error when attempting to load a file via the www object, but when I moved the file to a different location on the disk, the loading worked.

I then tried loading any of the .wav files in the original location, and none of them would load until moved to a different folder.

I will attempt to set up a concrete example when there is time, but maybe this information will help you.

I had the same issue when "split" APK (Error: Cannot create FMOD::Sound instance for resource). For correct this, i uncheck "Preload Audio Data" for all Audios (Assets .wav) in the game.

My Unity version is 5.3.4f1.

have same issue in 5.3.4, why it's marked fixed?

I'm getting this error in the editor (v5.3.3f1).
using AssetBundles for WebGL

I have the same issue in Unity 5.3.3f1, when splitting Android build to apk + obb:

Error: Cannot create FMOD::Sound instance for resource sharedassets0.resource, (File not found. )
Function SoundHandle::Instance::~Instance() may only be called from main thread!
Unhandled Exception: System.ExecutionEngineException: SIGILL

I'm still getting this problem on Unity 5.3.2f1, along with "(Operation could not be performed because specified sound/DSP connection is not ready. )". Is there a known workaround for this issue?

Still happening. It fives the "Cannot create FMOD::Sound instance for resource (null)" error in the editor, but the build crash at this point:
Receiving unhandled NULL exception
Obtained 29 stack frames.
#0 0x00000100f8cac1 in BaseVideoTexture::InitVideoMemory(int, int)
#1 0x00000100f8b203 in MovieTexture::ReadyToPlay()
(…)

Scrap that - somehow NET profile got set to "2.0 subset" changing it to "2.0" within unity player settings fixed the problem for me.

I'm still getting this error on ios builds for 5.3.3, is anyone else still getting it or was there a resolution ?
