I’ve just updated my FMOD 1.08 to 1.10. When I made the fmod build and loaded up my unity project (I have the FMOD settings set to Project in Unity) I have no sound and get this error:

“FMOD Studio: Encounterd Error: ERR\_VERSION The version number of this file format is not supported.  
UnityEngine.Debug:LogError(Object)  
FMODUnity.EditorUtils:CheckResult(RESULT) (at Assets/Plugins/Editor/FMOD/EditorUtils.cs:27)  
FMODUnity.EventManager:UpdateCache() (at Assets/Plugins/Editor/FMOD/EventManager.cs:129)  
FMODUnity.EventManager:Update() (at Assets/Plugins/Editor/FMOD/EventManager.cs:547)  
UnityEditor.EditorApplication:Internal\_CallUpdateFunctions()”

Could anyone please help me figure out why this is happening?  
Is FMOD 1.10 not compatible with Unity 5.3.3f1?

I even tried adding the FMOD build to the unity assets folder, and still gives me the same thing ☹

You have to update FMOD plugin in Unity, too
