Tried with changes from amd-staging-4.15 up to v4.15-829-g8a2a2ac :


[lakostis@lks ~]$ fgrep -r monitor /proc/asound/HDMI/
...
/proc/asound/HDMI/eld#0.0:monitor_present               0
/proc/asound/HDMI/eld#0.1:monitor_present               0
/proc/asound/HDMI/eld#0.2:monitor_present               0
/proc/asound/HDMI/eld#0.3:monitor_present               0
/proc/asound/HDMI/eld#0.4:monitor_present               0
/proc/asound/HDMI/eld#0.5:monitor_present               0
[lakostis@lks ~]$ 

Still no sound or it's presence detected.
