Found the offending commit:
Did not verify this, but I suspect this is the case:
After this change, the driver will not report Jack_is_plugged event
through hdmi_present_sense_via_verbs() if monitor_present is 1 and
eld_valid is 0.

ALSA: hda/hdmi - Consider eld_valid when reporting jack event
commit 7f641e26a6df9269cb25dd7a4b0a91d6586ed441 upstream.
On the machines with AMD GPU or Nvidia GPU, we often meet this issue:
after s3, there are 4 HDMI/DP audio devices in the gnome-sound-setting
even there is no any monitors plugged.
When this problem happens, we check the /proc/asound/cardX/eld#N.M, we
will find the monitor_present=1, eld_valid=0.
The root cause is BIOS or GPU driver makes the PRESENCE valid even no
monitor plugged, and of course the driver will not get the valid
eld_data subsequently.
In this situation, we should not report the jack_plugged event, to do
so, let us change the function hdmi_present_sense_via_verbs(). In this
function, it reads the pin_sense via snd_hda_pin_sense(), after
calling this function, the jack_dirty is 0, and before exiting
via_verbs(), we change the shadow pin_sense according to both
monitor_present and eld_valid, then in the snd_hda_jack_report_sync(),
since the jack_dirty is still 0, it will report jack event according
to this modified shadow pin_sense.
After this change, the driver will not report Jack_is_plugged event
through hdmi_present_sense_via_verbs() if monitor_present is 1 and
eld_valid is 0.

Title:
HDMI audio not available RS880 between 4.9.177 and 4.9.178
Status in linux package in Ubuntu:
Confirmed
Bug description:
This is on my friend laptop with his TV.
HDMI audio not available in pavucontrol (profile say unplugged, unavailable)
in kernel versions with bugs.
It is just shown as an audio output (HDMI audio) on kernels where it is
working.
When not working, I can play with aplay -D HDMI ...
When working... I select HDMI audio in output, and test sound ok, Youtube
videos ok, etc.
4.9.177 working.
4.9.178 not working.
I suspect commit 72cf0b07418a9c8349aa9137194b1ccba6e54a9d because it
is between those versions, and is related to audio (realtek in part).
More info at:
https://forums.linuxmint.com/viewtopic.php?f=49&t=383607&p=2246352#p2246352
although the laptop now runs ... 17.10 I think (a version with a not broken
kernel).
