When I open the web widget, I do get sound. I’m using a web widget inside a blueprint, so that it can be seen as a regular actor in VR. I’m trying to do the opposite: how to mute. The web widget C++ code doesn’t have much in it to interact with the browser. The only thing available is a call for javascript. So it might be possible to turn on/off the web widget browser using the javascript call. Yet, the target URL would need to have a function to enable/disable sound for whatever player is being loaded. Its not a general function for the entire browser. At least, Chrome at the moment doesn’t give access through its interface to mute other than using the mouse on the main google menu.
