FMOD failed to initialize the output device

So i am on Unity 5.6.0b10 and was fiddling with Video player on a WebGL build. So everything works fine in editor, but when building it to WebGL it throws an error on chrome, mozilla firefox and safari.

So even after throwing error in safari video plays but in chrome and mozilla firefox video doesn't plays. In chrome i get following error :

In video player component 'Play on Awake' is set to true and 'Render mode' is set to Material over ride with mesh renderer of a sphere, rest all are default value.
here is a snippet of my code :

Code (CSharp):

1. vPlayer.url = Application.streamingAssetsPath + "/Chrome_ImF.mp4";
2. vPlayer.Prepare();

All i want is to make video player work on WebGL build with video being set from url or streaming assets.

Thanks
