I am using the gitcompile script to configure, compile... 
There is no configure by default, I was able to autogen it, but then
I had issues while building so I reverted back to gitcompile

seem the max number of playback streams is hardcoded in the driver

Indeed it is hardcoded to 1 (previous ATI/AMD codecs had a single HDMI pin). This is almost certainly not true anymore.

I wonder what the limit is now, maybe the amount of HDMI pins so that there can be 6 or 7 independent streams? Alex?

Does this mean monitor is plugged and graphic driver is requesting monitor to provide EDID ?

The above means that no monitor is plugged in (Presence_Detect=0 on all HDMI pins).

And this means the codec reports monitor in all the pins (Presence_Detect=1), but the monitor information is missing on all pins.

I'm only getting bits and pieces of the conversation here, but this looks like a log from an older kernel without full AMD support as the driver tries to use generic ELD methods on AMD hardware (on newer kernels, the monitor info is shown in the correct pin and only that pin). The presence detect stuff is unchanged on newer kernels, though.

This is ALSA driver retrying reading monitor information (still fails as not supported by this driver).

Does this mean the graphic driver received EDID from DENON-AVAMP and pass ELD to audio driver ?

ATI/AMD does not internally use ELD but analogous custom stuff. But as noted, the HDA driver on this kernel does not support reading it, it is a 3.12+ feature (though note that writing the info is disabled in 3.12 radeon video driver on some cards).
