Media rules (and Applicability) could auto-detect embedded play button and autoplay attribute

[Jym77]

When the <audio> element has controls, Alfa could assume that it includes a play button and avoid asking the question.

Alfa could use the autoplay attribute and assume the audio is playing.

(R49 is already doing that)

Media rules are the 20s and 30s.
There are shared Applicabilities and Expectations.

According to Mozilla autoplay guide most browsers block autoplay unless certain conditions are met for example if the audio is muted it won't be blocked (<audio controls autoplay muted>...).

Do we still want to assume it's playing based on this? We could also refine it to also look for muted. The other conditions listed doesn't seem to by something Alfa can know, so I'm wondering if we should still ask questions unless muted is present.

Yes, I thing we should assume it plays when autoplay is present.
It, at least, indicates intention by author to have it autoplay if possible, so it is also an author responsibility to provide means to stop the media.
This goes together with some recent ACT rules discussion about the topic of autoplay.
