Hello, I cannot get my unity script working as intended with PLAYBACK\_STATE and I absolutely don’t know why.  
I just spent my day trying to understand but I am still stuck.

Using Fmod 2.02 + Unity 2020.3.39f1.  
I use my script to check if a sound is playing in order to not play it again once it is already playing but the PLAYBACK\_STATE is always STOPPED. So it keeps restarting the sound each frame.

Here is the script I use :  
To explain a bit, I call PlayOneShotAttachedToGO() at only one place in the update of another script.

```auto
using FMOD.Studio;
using FMODUnity;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class AudioPlayer : MonoBehaviour
{
    public EventReference soundEventReference;
    EventInstance soundStateInstance;

    void Start()
    {
        soundStateInstance = RuntimeManager.CreateInstance(soundEventReference);
    }

    public PLAYBACK_STATE playbackState;

    public void PlayOneShotAttachedToGO()
    {
        if (soundStateInstance.isValid())
        {
            soundStateInstance.getPlaybackState(out playbackState);
            if (playbackState == PLAYBACK_STATE.STOPPED)//keeps being STOPPED even if the sound is playing in game
                RuntimeManager.PlayOneShotAttached(soundEventReference, gameObject);
        }
    }

    public void PlayOneShotToTransformPosition()
    {
        if (soundStateInstance.isValid())
        {
            soundStateInstance.getPlaybackState(out playbackState);
            if (playbackState == PLAYBACK_STATE.STOPPED)
                RuntimeManager.PlayOneShot(soundEventReference, transform.position);
        }
    }

    public void StopSound()
    {
        if (soundStateInstance.isValid())
        {
            soundStateInstance.getPlaybackState(out playbackState);
            if (playbackState == PLAYBACK_STATE.PLAYING)
                soundStateInstance.stop(FMOD.Studio.STOP_MODE.IMMEDIATE);
        }
    }
}

```

I cannot understand what is happening and why when I hear the sound played in-game in unity it keeps being STOPPED.

I hope someone will have a solution. Also, it’s no use to propose to get back on 2.01 because I was forced to upgrade to 2.02 because 3D spatialized sound was not working.

Hi,

So the problem is the `soundStateInstance` is not the same event instance that `PlayOneShotAttached` is creating/using. Since `SoundStateInstance` is never played it will always return Stopped.

A solution would be to implement your own `PlayOneShotAttached` based on how we have structured it in the `RuntimeManager.cs` script. To find its implementation highlight `PlayOneShotAttached` in your script and press F12.

Hope this helps!
