It turned out there were alsa-related entries in a modprobe*.conf
(added by Ubuntu and/or possibly by the laptop's owner). Removed
the options.
7.3.4: added the ghost_rt711 quirk patch (already in v7.4).
7.4-rc2: added the ASoC: soc-core: reset rtd->num_components after
allocation patch from Emanuele Ghidoli.
Now the laptop shows certain output devices in GUI mixers. They are
... silent, though. This is now similar on 7.3.4 and 7.4-rc2. The only
visible difference is that 7.4-rc2 warns about the ssp2-bt-id8:
sof_sdw sof_sdw: Failed to open topology file: intel/sof-ipc4-tplg/sof-lnl-ssp2-bt-id8.tplg, ...
and 7.3.4 does not.
I have no idea how does the SOF/soundwire work. But (using 7.4-rc2
at the moment) I killed the wireplumber/pipewire daemons, and
alsamixer/amixer -c0 both start, showing many controls (139, not
counting input). Experimented a bit with them, and now is seems
aplay *.wav -D plughw:CARD=sofsoundwire,DEV=5 produces sound on the
built-in speaker(s). Then.. pipewire works now, so I consider this
problem solved. It also works on 7.3.4+.
Thank you, and sorry for the false alarm.
For reference (removed some amount of noise from dmesg):
