Hi all, I am very new to Fmod and coming from a healthy Wwise background.

I am running into an issue in Unity where I cannot get UI sounds to play via ‘FMOD Studio Event Emitters’, nor by writing a script to play a sound when an event is referenced.

**Description**  
None of the Events from the Event Emitter trigger the sound aside from Object Start (pic below). I can play audio triggered by Object Start but nothing else. Soundbanks are loaded.

I have searched through forum posts and tutorials but I am completely lost. I feel like I am missing something really simple. I have found a lot of resources which resolve my problems using the deprecated EventRef function…

Resources that I have found but which were not helpful. (edit can only attach two, being a new user)

- [Tutorial from 2021 which uses deprecated EventRef](https://youtu.be/9RLz79LZP2k?t=222)  
This script would solve my issue but it uses an outdated function.

- [2022 tutorial How To Use EventReferences & PlayOneShotAttached();](https://www.youtube.com/watch?v=t7X7eVu4cA4)  
This goes into editing the RuntimeManger…not quite what I need.

Hi,

`Mouse Enter` is intended to work on GUI elements explained in the Unity Docs here: [Unity - Scripting API: GUI](https://docs.unity3d.com/ScriptReference/GUI.html)

To have a UI Button make a sound when the mouse highlights it you could do something like this:

```auto
using UnityEngine; 
using UnityEngine.EventSystems; 

public class MouseOver : MonoBehaviour, IPointerEnterHandler
{
    public FMODUnity.EventReference hoverSound;

	public void OnPointerEnter(PointerEventData eventData)
	{
		FMODUnity.RuntimeManager.PlayOneShot(hoverSound, this.transform.position);
	}
}

```

This will play a OneShot whenever the mouse hovers over the button. Important bits are `using UnityEngine.EventSystems` and `IPointerEnterHandler`.

I’ll make a note to add in the docs this is a bit confusing.
