Hello, yes, now I have tried to boot from an Ubuntu 22.04 install USB and choose “Try Ubuntu”. The short answer is yes, there is no sound when using the install USB and when checking the dmesg for snd_hda_intel there are exactly the same problematic error messages as highlighted in this thread.
So then we have concluded that it is not my “configuration” of the installed OS on the harddrive/ssd that is the issue.
Perhaps making a 18.04 install USB could help figure out how it should work when working properly
Edit: I found the command journalctl -b. If you want the full output let me know. Here is the output I found that is related to audio (I have cut here and there)

(there are a number of i915 error messages but it is not clear whether they are due to audio or video issues)
I just found a thread on how to debug audio. Will post output from the instructions there soon
