Hi,all.I had a problem when I am using fmod in Unity.I want to set 3D sound mute,so I do that:  
FMOD.Studio.EventInstance event = FMOD\_StudioSystem.instance.GetEvent(path);  
event.setVolume(0f);  
but the sound is not mute;so I want to know whether I can do that.  
I’m looking forward to answering this question ,thank you.

FMOD\_StudioSystem.instance.GetEvent() returns a new instance of the event.

You need to call setVolume() on the previous instance.

Thank you and answer my question, Yes,I’m coding according to your example:  
engine = FMOD\_StudioSystem.instance.getEvent(“event:/Vehicles/Car Engine”); engine.start();  
engine.stop();  
I can control the event start and stop,but I can not control the event volume,if I want to set the Volume, what should I do?I can do it in 2d sound by using event.setVolume;but it is useless when I do it in 3d sound.Thank you.
