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?
