Bug 1434804 - Pause autoplayed media if they become audible. r=kamidphish Our autoplay blocking is trivial to defeat; just mute or volume=0 a video, play(), and then unmute, and then you're playing audibly. So this patch makes us pause() media that become audible atfter playback has started. MozReview-Commit-ID: 2RAtbohMGJO
