No HDMI sound on Intel NUC10i5FNK

I have been trying to get sound over HDMI working for 5 hours straight but so far only failed. I just bought this little machine, so I haven't tried any other OS.
The HDMI cable works fine with an older Gigabyte BRiX, albeit with an Intel Haswell HDMI controller.

i@nuc2:~$ hostnamectl | grep -P 'Kernel|Model'
          Kernel: Linux 5.13.12-arch1-1
  Hardware Model: NUC10i5FNK

All I see in alsamixer are the items "S/PDIF" and "S/PDIF 1", both of which are at "00" and cannot be raised, only muted/unmuted.

Including some information that have been requested in other sound issue threads, let me know if something else could help.

i@nuc2:~$ lspci | grep Audio

I don't know how to get these to not be in a suspended state.

I have tried generating sound with

speaker-test -D plughw:0,3 -c 2
speaker-test -D plughw:0,7 -c 2
speaker-test -D hdmi:PCH -c 2

but never hear anything from the speakers.

Searching elsewhere on the net led me here which gave me some hope, but no success.
I tried both of these (with reboot after each):

i@nuc2:~$ cat /etc/modprobe.d/snd-hda-intel.conf
options snd-hda-intel model=auto

i@nuc2:~$ cat /etc/modprobe.d/snd-hda-intel.conf
options snd-hda-intel model=generic

Finding the codec

i@nuc2:~$ grep Codec /proc/asound/card0/codec#2 
Codec: Intel Kabylake HDMI

which they also suggested there did not help, as I cannot find the documentation locally and do not know which package provides it.

You have a sof card, install the sof-firmware and alsa-ucm-conf packages.

from this thread seemed promising, but didn't work, not even with the modprobe options.

What can I try?

Re: No HDMI sound on Intel NUC10i5FNK

Your HDMI device is present (two SPDIFs you can only mute or unmute is exactly what you're expected to see means from a detection standpoint you're where you want to be), if you do not get any audio output then that often means your monitor/DAC/whatever setup is wrong.

I suggest you revert everything you did in an attempt to fix this, get rid of the modprobe options, get rid of the manual device loading in pulseaudio, reboot and post a fresh

aplay -lL
pactl list cards
pactl list sinks
sudo fuser -v /dev/snd/*
speaker-test -Dhw:0,3 -c2

Then the elephant in the room. What are you connecting this to? if a monitor check in the monitor settings that it isn't muted, if some other DAC make sure it outputs from the correct input into the correct output.

It's connected to a TV with ARC to a soundbar. If I swap this NUC with one of my other computers, then I get sound via HDMI, so I'm assuming neither the TV nor the HDMI cable is causing the issue. Nothing is changed on the TV/soundbar.
The biggest difference with this NUC from other PCs is that it doesn't have any other audio ports, which just adds to the frustration.
