However, this should have eld_valid=1 and contain more info. To get a
hint on whether it is a bug in audio or video driver, could you give a
log with CONFIG_SND_DEBUG ?

AFAICS the sound git master tree should have the necessary support in
the radeon video driver to allow the audio driver to generate a valid
ELD with your card.
