This fix comes from kernel side, so downgrade Mesa or not should not affect it.

[Kai-Heng Feng]

This commit fixes the issue:

commit 2d8f63297b9f0b430c96329893667c0bfdcbd47e
Author: Jani Nikula 
Date:   Tue Sep 19 18:38:13 2017 +0300

drm/i915: always update ELD connector type after get modes

drm_edid_to_eld() initializes the connector ELD to zero, overwriting the
ELD connector type initialized in intel_audio_codec_enable(). If
userspace does getconnector and thus get_modes after modeset, a
subsequent audio component i915_audio_component_get_eld() call will
receive an ELD without the connector type properly set. It's fine for
HDMI, but screws up audio for DP.

Always set the ELD connector type at intel_connector_update_modes()
based on the connector type. We can drop the connector type update from
intel_audio_codec_enable().

Credits to Joseph Nuzman  for figuring this out.

It is v4.14-rc4 which produced sound without playing with pulseaudio or
restarting display.

[Rael Gugelmin Cunha]

Well, to be honest, it was your tip about the dpms that I followed!
Thanks!

I just made a bit different: I've added a line to the xset call in the
pulseaudio startup script (the sleep call was not required, just the
xset one). Details here: https://askubuntu.com/a/969935/138621

And now sound is working on retroarch! Again, thanks!

[Olivier Doriath]

@Rael That is odd. My TV and cable are way too old to be 2.0 (circa
2008-2009 I believe) and yet the firmware went through and the version
number changed. Then again the 2.0 update doesn’t fix anything for this
issue. I am also using the 1 second workaround for now!

@Olivier, I installed a Win10 yesterday with no activation key, and ran
the upgrader tool in a old HDMI TV, and the upgrader said it cannot
upgrade (according the PDF is because my TV is not HDMI 2).

Anyway, I ran a workaround: edited pulseaudio config to power off the
display for 1 second and my sound is now working (at least for the
applications I'm running).

and TV! (afaik)

The Intel firmware upgrade is intended only for HDMI 2.0 displays. And,
interestingly, you can install it only if NUC is attached to a HDMI 2.0
device.

Interesting to see Intel released a firmware update specifically for
HDMI on the NUC. If you can boot Windows to install it then it might be
worth trying for NUC owners like Neilen...

Hi,

It seems that newest kernel candidate (from http://kernel.ubuntu.com/)
v4.14-rc5 mainline build fixes the sound issue. But on the other end it
kills LAN :)

I was close to submit missing log file. 
The command returned that I am not the owner of this bug (translated from 
Polish :)

How I can contribute?
I would be really happy to get the HDMI working properly on my ASRock J4205-ITX.
I know it is not a major issue nor the hardware popular - but Win10 works 
out-of-the-box.
