I don't see anything obvious, but the names and the functions of the

In this case there are not too many of them, only 'PCM', 'Front',
'Line', 'Mic', 'IEC958', 'Capture', 'Capture', 'Input So', 'Input So.'

You could keep speaker-test running in one terminal while using
"alsamixer" in another terminal to play with the controls until you hear
sound.

That was fun. I think I tried every permutation. PCM has only volume;
Front, Line, and Mic have volume and mute; IEC958 has only mute; the two
Captures have volume and <space> toggles a display of
L R
CAPTUR
beneath, whatever that may mean (stereo on and off?); the two Input So.
have only the option to be Line or Mic.

Anyway, it remains steadfastly silent in every conceivable state while
speaker-test continues to say
Time per period = 2,986811
0 - Front Left
and so on.

OK, changing mixer settings does not help; there must be a more
fundamental problem with the driver or the hardware.

It is not hardware, I have booted Doze a couple of times, and that gives
nasty little jingles.

OK, so the hardware works.

Never mind -- I'll buy a phonograph, a soft cloth and scour the
second-hand markets for vinyl...

To keep yourself entertained until you get the phonograph, you could
post the output of these commands:

cat /proc/asound/card0/codec* | head

grep '.*' /sys/module/snd_hda_intel/parameters/*
