UNITY - SetVolume(0) not muting the volume of Event

FMOD Studio
1

Using Fmod Studio with Unity and trying to mute an Event but not working.
I’m using setVolume(0) to mute it and debugging with getVolume()

No matter what I set under setVolume, the getVolume() ‘finalVolume’ doesn’t change.
I’m sure I’m doing something wrong, but not what.

This is how I initialize the event in Unity:

//Create event
audioProperties.musicInstance = FMODUnity.RuntimeManager.CreateInstance(eventRef);
FMODUnity.RuntimeManager.AttachInstanceToGameObject(newAudioInstance, parentSource.GetComponent(), parentSource.GetComponent());
audioProperties.musicInstance.set3DAttributes(FMODUnity.RuntimeUtils.To3DAttributes(parentSource.transform));

//Start event and mute it
audioProperties.musicInstance.start();
audioProperties.musicInstance.setVolume(0);

Any help greatly appreciated!

I’m not aware of any reason why that would not work.
Most FMOD functions will return a FMOD.RESULT, which if it fails will give you an indication as to why.

You could also check the fmod log (found in the menu FMOD/Log Viewer).

Thanks for the help. I’ve figured it out. I had another function on update doing a setVolume(1) to all audio sources every frame, so it just kept reverting…my bad!

I’m having a very similar issue. Except I don’t have any other setVolumes happening, and when I check the volume afterward via getVolume, it did save the setting, except it’s still playing at full volume.

code looks like this

{

FMOD.Studio.Bus bus;

private float busVolume;

private float currentVolume;


void Start()
{
  bus = FMODUnity.RuntimeManager.GetBus("bus:/In Game");
  UpdateVolume();
}

void OnEnable(){
  SettingsMenu.SoundUpdate += UpdateVolume;
}

void OnDisable(){
  SettingsMenu.SoundUpdate -= UpdateVolume;
}


void Update()
{

}


void UpdateVolume(){
  busVolume = PlayerPrefs.GetFloat("BGMVol", 0.5f);
  bus.setVolume(busVolume);
  bus.getVolume(out currentVolume);
  Debug.Log(currentVolume);
}

}

What is the value range you are passing into setVolume? Have you tried checking the results to see if the getVolume and setVolume calls are passing? i.e

void UpdateVolume()
{
    busVolume = PlayerPrefs.GetFloat("BGMVol", 0.5f);
    FMOD.RESULT result = bus.setVolume(busVolume);
    if (result != FMOD.RESULT.OK) Debug.Log("Failed to set volume!");

    result = bus.getVolume(out currentVolume);
    if (result != FMOD.RESULT.OK) Debug.Log("Failed to set volume!");

    Debug.Log(busVolume);
    Debug.Log(currentVolume);
}
