Wouldn't hurt to file a bug (https://bugs.freedesktop.org). Daniel Vetter has a set of patches that reworks the common hotplug handling that may fix this: http://lists.freedesktop.org/archives/dri-devel/2012-May/023407.html > > >> Hotplug should work, and doesn't really have anything to do with hdmi >> audio per se.

No ELD for radeon? Sigh. Again - is this being worked on? You need to load radeon with the audio parameter to enable hdmi audio (e.g., radeon.audio=1 on the kernel command line in grub). As for ELD support, I'm not sure what's missing, I'm not really that familiar with the audio side.
