Hi,  
I have a problem with FMODUnity.RuntimeManager.MuteAllEvents().

I want to mute all sounds on Master Bus “bus:/” and it should work straight away I think. There are no errors in Unity console, no warnings etc.  
FMODUnity.RuntimeManager.PlayOneShot() works perfectly. Controlling custom parameters from Unity works great.

**Are there any special things to consider while using MuteAllEvents()?**

I’ve searched on various sites for solution but found nothing ☹

Thanks for any help!

FMOD Studio 1.09.02  
Unity 5.5.1f1

edit:  
I also tried this based on [https://www.fmod.org/questions/question/how-do-you-script-volume-control-for-music-and-sfx-buses/](https://www.fmod.org/questions/question/how-do-you-script-volume-control-for-music-and-sfx-buses/):

string masterBusString = “bus:/”;  
FMOD.Studio.Bus masterBus;

masterBus = FMODUnity.RuntimeManager.GetBus(masterBusString);  
masterBus.setVolume(float); - works great  
masterBus.setPause(bool); - works great  
masterBus.setMute(bool); - doesn’t work at all…

So workaround for now is to use masterBus.setVolume(0.0f)/masterBus.setVolume(1.0f) to simulate mute/unmute or just masterBus.setPause(true/false).

The question remains - **why setMute() does not work?**

Hm, I can’t tell you the problem with the method MuteAllEvents, but I’m using

```
Bus musicBus = FMODUnity.RuntimeManager.GetBus("bus:/Music");
musicBus.setMute(true);

```

That works really well. So You could create a masterbus which is the parent of all other buses and just mute that one 🙂

Oh just saw your edit… strange setMute does work for me.  
Unity 5.6.0p2  
Fmod 1.09.04

Another workaround, thanks! It works indeed 🙂

MuteAllEvents should take a bool parameter for pausing and unpausing.

In the RuntimeManager.cs you can see what MuteAllEvents does:

```
public static void MuteAllEvents(bool muted)
    {
        GetBus("bus:/").setMute(muted);
    }
```

Yes, I know this, but it doesn’t work for me as described above. Thanks for your answer anyway 🙂

I know this is old, but if the problem is only in Unity Editor, then it is caused by RuntimeManager Update function, which calls `MuteAllEvents(UnityEditor.EditorUtility.audioMasterMute);`

So to mute sounds in Unity Editor, you need to do sth like this:

```auto
#if UNITY_EDITOR
UnityEditor.EditorUtility.audioMasterMute = true;
#else
RuntimeManager.MuteAllEvents(true);
#endif

```
