Does ASoC support 'hotplug' of audio devices? If so, maybe it makes some sense to have some support in drm core. At least all the edid parsing stuff to determine if the display supports audio should be generic and not driver specific.

Not really (except on a card level), and it'd probably confuse most userspaces. What I'd expect to happen currently is that the current state of the connector would get reported via extcon.
