Ok, … then lets see if we can force a different alsa configuration upon boot. I will give you a list with many different configurations (options) to try, and you need to try each one, one at a time, restarting your alsa driver in between each attempt. From the alsa documentation, in the HD-Audio-Models.txt file (where this is a copy of this file buried in a location on your PC hard drive) for the ALC889A (which according to the diagnostic script is the hardware audio codec on your physical PC) the list of options that can be tried are:
ALC882/883/885/888/889

Thats a big list ! And like you, I have no idea as to which one is appropriate. So I recommend you try that one at a time until you find one that works. Pay close attention to your mixer settings, as one of them may give you more HDMI devices/controls than the others.
To try an item in that list (lets say you decide to try “3stack-6ch-dig”) then you need to ADD the following line to the START of your /etc/modprobe.d/50-sound.conf file:
options snd-hda-intel model=3stack-6ch-dig
Save the change.
… and then restart your alsa sound driver and restart your mixer. You can do this by restarting your PC. OR you can do it by typing in a terminal with root permissions
rcalsasound restart
and if asked in KDE if you wish to keep an old configuration, select no. And then in a terminal as a regular user restart your mixer (type ‘kmix’ on kde, … or possibly ‘alsamixer’ on gnome). Then test the HDMI. Check the mixer settings (you can run that diagnostic script). LOOK FOR DIFFERENCES. This new configuration may completely break your sound. No worries. Just change or remove the configuration, trying each one, ONE at a time.
ie if you wish to try ‘intel-alc889a’ you replace ‘3stack-6ch-dig’ in that edit, save the change, and restart the sound driver and test.
… Good luck.
