This is related to this issue: https://issuetracker.unity3d.com/issues/fmod-sound-instance-for-resource-error However, this has been marked resolved even though other folks are still having issues with it lately. Essentially it's more or less the same issue. I added an audioclip or a prefab that contains an audioclip into an assetbundle. I download the assetbundle and when I try to load the sound or play it.. i get this error: Error: Cannot create FMOD::Sound instance for resource archive:/CAB-5e34325c94d401ceeb19d7d8f7305374/CAB-5e34325c94d401ceeb19d7d8f7305374.resource, (Unsupported file or audio format. ) UnityEngine.AudioSourcelayOneShot(AudioClip) Has anyone found a work around for this?
