I’m getting FMOD script errors during webgl build but everything works fine in editor  
`Assets\Scripts\Audio\FMODEventInstanceManager.cs(24,45): error CS1061: 'EventReference' does not contain a definition for 'Path' and no accessible extension method 'Path' accepting a first argument of type 'EventReference' could be found (are you missing a using directive or an assembly reference?)`

Here is my script

```auto
// Constructors can now delegate to the private method
        public FMODEventInstanceManager(EventReference soundEvent, int eventMaxCount)
        {
            CreateEventInstances(soundEvent.Path, eventMaxCount);
        }

        public FMODEventInstanceManager(string soundEventPath, int eventMaxCount)
        {
            CreateEventInstances(soundEventPath, eventMaxCount);
        }

```

The problem with the code is that `Path` is only used within Editor, to fix this we need to do `soundEvent.ToString()`
