Help with HTML5 Game Webview

I have a webview app that I obviously use for HTML5 Games. Im getting the apps suspended a lot because the app continues to make sound for a few seconds after exiting the application. Also according to the reviewer the volume does not go away during a phonecall or in the “HOLD MODE”

What I think would be easiest would be to completely mute the app. I am willing to have every app silent in order to avoid suspension. Does anyone know what I can do to mute the application. The tough part is the volume is coming from webpage and not necessarily the app itself.

Hope I can find a remedy :slight_smile:

Cheers!
