You could try:

Thanks, I tried it and no fix. I selected many of the resets.

Hey - check this:

Open "Control Panel" > change view to "Category"
Double click on "hardware and sound"
Double click on "sound"
Right click on "speakers"
Left click on "configure speakers"
Select "Stereo" if your system has simple stereo. If you select "surround sound" setting it might cause the problem.
Left click on "next" and complete the operation.

Relaunch browser and test.

You fixed it, it plays that youtube video. It was set to surround for some reason. I do have stereo speakers and 1 woofer. An old speaker set made by dell.

Turned out to be a simple fix, very much appreciated, I clicked the thanks up button for you.

And those weather.com videos are playing sound.
