IE 11 no Sound on FB videos

[I love a sunflower]

I've recently bought a new Netbook Asus X551 MAV, using windows 10, IE 11.
When playing Facebook videos there is no sound on them, my own home movie type videos and funny videos also.

If I play a YouTube video on facebook there is sound, but not other videos.
All the sound bars are turned on, not muted etc, the sound application is set to on.

I installed Firefox to see if it all worked on there and it does, so why doesn't it work on Internet Explorer 11.

Facebook uses Adobe flash player and the latest player is installed with Windows 10, any ideas how to get it to work.

You could try right clicking on the video and bringing up flash player settings.

If you bring up the volume mixer there should be application specific sliders for the applications that are running. Are those the ones you're referring to?

Hi yeah that's all good.

I don't seem to be able to update flash and it is enabled in the tools = manage add ons
