I would prefer to make the choice to listen to something as I open the main page as opposed to having all manner of things begin to blare at me and then going through the motions of turning it all off. I ask that autoplay be turned off on these items... please!
I third this suggestion, it is rather annoying. I tend to open my browser and open 4 or 5 things at once and then get to them one by one. I keep hearing sound and then I have to work out where it is coming from, most annoying!
