I played a bit more round this eld thing and it seems there is a bug - but it looks like it's the same for older radeon dce as well, and "fixing" it doesn't get me sound on the TV - it does of course make /proc/asound eld look saner.
The difference between my monitor and the TV is that the monitor has a speaker layout block and the TV doesn't. So the monitor hits the the "if" in the attached diff and the value of sadb[0] is 1.
The TV hits the else and gets allocated a value of 5 which is commented as stereo, but according to the edid sections of CEA B and D stereo is 1 and 5 is just like I see in /proc/asound Fl/Fr Fc.
