> Quoting the blog post, Google’s decision that ”Muted autoplay is always allowed” is the problem. If any other Chrome users wondered why videos now auto-play without sound (even with this option set), at least based on the relatively minimal docs about this flag, this is why.
Which, sadly, does not actually work for me. I've had it disabled since it first appeared and it has barely made a difference. At least for the news site that play unwanted video. The best I've been able to do in Chrome is to block anything that looks like a CDN using Privacy Badger.
Just tried it. Didn't work. First off the only options are "default", "no user gesture required", "user gesture is required for cross-origin iframes", "Document user activation is required". None of which sounds like "disable autoplay"
Set the flag to "Document user activation is required", restarted browser, went to youtube, videos autoplay
It seems to work intermittently for me at best. Bloomberg is a notable (notably annoying) example that not only autoplays (though at least without sound) but highjacks your first click on the video (usually trying to pause it) and enables sound instead.
