Is there any reason for you to disable on-board hda controller and alc888
as you don't have any capture device anymore ?

pactl list

Do pulseaudio server select null sink or hdmi.monitor as the default source

strange that all jacks return true
    control.1 {
        iface CARD
        name 'HDMI/DP,pcm=3 Jack'
        value true
        comment {
            access read
            type BOOLEAN
            count 1
        }
    }
    ...

    control.31 {
        iface CARD
        name 'HDMI/DP,pcm=11 Jack'
        value true
        comment {
            access read
            type BOOLEAN
            count 1
        }
    }


cat /proc/asound/card0/eld#*.0

does your hdmi montior name appear in one of the six eld


[    5.468413] [drm] Connector 2:
[    5.468414] [drm]   HDMI-A-1
[    5.468415] [drm]   HPD1


Does the graphic driver show which hdmi monitor connect to which ports in
system log ?
