After some discussion on IRC, I think Jonas, Hixie and I agreed that
we're OK with the following approach:
-- sound is produced for display:none elements and elements not in the
DOM
what about people hiding ads or other elements via greasemonkey scripts
(and so on) - using display:none hacks to remove from visibility? If
naming is an issue, how about a new css element of active:none; which
prevents any video/sound/display playing.
The greasemonkey script could easily find all audio/video elements and
stop them.
-- removing an element from the DOM automatically calls stop() on that
element-- tearing down the owner document always stops the element
playing (so navigating away from the page always stops sound)
Therefore
myAudio = new Audio("foo.wav");
myAudio.onload = function () {
this.play();
myAudio = null;
}
will work, and will play until the sound ends or the user leaves the
page.
Is there still a way to find this element in the DOM? Again, thinking
about greasemonkey scripts which want to kill all sound in a page.
No, there is no way to find these elements. Ideal is if UAs expose some
internal API that extensions can use to mute the sound on the page.
