Errors in editor when attempting to play an audio clip from asset bundle

[liortal]

We are using asset bundles, and some of the bundles contain a reference to an AudioClip asset.

I just started noticing these errors when loading the bundles (or when attempting to play the audio clip):

Error: Cannot create FMOD::Sound instance for resource archive:/CAB-4eb48bb7489d7aedc273d7d14f17d986/CAB-4eb48bb7489d7aedc273d7d14f17d986.resource, (Unsupported file or audio format. )

Sometimes the error is also followed by:

Function SoundHandle::Instance::~Instance() may only be called from main thread

It seems that asset bundles that are built for WebGL cannot play the audio clip while in editor.

Is there a known bug for this ? should I report this ?
*We are using Unity 5.3.4p1

Here’s a screenshot of the AudioClip import settings, maybe this issue is related to that (there are no overloaded settings for WebGL):

Has already been reported but I dont think Unity considers it a “bug”:

AudioClips not playing in WebGL when downloaded with AssetBundles

Any content from an assetbundle built for a target platform OTHER than the dev machine platform (i.e, Windows Standalone on Windows machine) is not guaranteed to work properly in the Editor. This is a bit frustrating but understandable in terms of assetbundles since different resources are required for different platforms.

Thanks for referring me to that thread. Kind of annoying, but we can live with it for now.
