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.
With CONFIG_SND_DEBUG=y I get a bunch of "HDMI ATI/AMD: no speaker allocation for ELD" but afaics that's about it.
Thanks, that is exactly what I was looking for.
Looks like a radeon driver issue - it does not seem to setup the speaker allocation registers properly (so that ALSA could read them from there), and I verified that the EDID you posted has a valid speaker allocation byte 0x4f.
Just to recheck - you are running sound git master, or something else?
This is from 3.12-rc7 with today's sound/master (3fbdaf9b) merged on top.
Ah, OK, that certainly explains it. 3.12-x has this one: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drive...
Could you revert that for testing, just to see if you get proper ELD info then?
Blergh, guess that's my fault for not just using sound/master.
But that looks better:
