The audio came back yesterday, but hard to tell what was the
culprit.
Anyway yesterday I updated every package to the latest from repo and
tested different things. I stumbled upon a software called PulseAudio
Volume Control and in its Output Devices tab I fiddled with its knobs
and suddenly the audio was back.
Good news!
One thing that might also play into this is that the OS shows two
output devices, when in reality I only have one monitor with built-in
speakers that I've been using since always. Settings -> Sound shows
two output devices, both named HDMI/DisplayPort - Built-in Audio.
PulseAudio Volume Control shows Built-in Audio Digital Stereo (HDMI)
twice.
Unless alsa has gone squirrely, the below is not your monitor. This
is a sound device built into your MB, and should have ports on the case.
The audio devices in monitors never have analog output, or at least
I've never seen that. The ALC892 is a realtek chip installed on MBs to
provide sound support. I guess it depends on what MB you are running,
but I don't think any x86_64 MBs come without built in sound support.
Maybe it is disabled / turned off?
