Now it suddenly stopped working again after a reboot although I did not change anything with the module options.
The output of alsa-info.sh for the non-working state I have now is attached.
Thanks. Through a quick glance, there is no significant difference between both outputs.

Please check /proc/asound/card0/eld#* (for the card number 0, as found in /proc/asound/cards as sof-hda-dsp). One of them should have a valid ELD entry. This is the first step. If no proper monitor and ELD is found in those, something wrong at the detection in the kernel.

That is OK, right?
Yes, looks so.
$ cat /proc/asound/cards 0 [sofhdadsp ]: sof-hda-dsp - sof-hda-dsp LENOVO-20WNS1F81R-ThinkPadT14sGen2i 1 [USB ]: USB-Audio - ThinkPad Thunderbolt 3 Dock USB Lenovo ThinkPad Thunderbolt 3 Dock USB at usb-0000:52:00.0-2.1.1.2, full speed
This is fine.
The next is to test aplay directly with the device. "aplay -L" will show the possible option, and you can try like
% apaly -Dhdmi:CARD=xxx,DEV=x -vv foo.wav
for a WAV file in a format matching with the supported device (typically 2 channel stereo 44.1kHz or 48kHz 16 or 32bit format). If this gets a busy error, stop wireplumber once during the test: % systemctl --user stop wireplumber % aplay .... % systemctl --user start wireplumber
If the aplay test doesn't work, again, it means that there's something wrong in the kernel.
$ file /usr/share/ibus-typing-booster/data/coin9.wav /usr/share/ibus-typing-booster/data/coin9.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 44100 Hz mfabian@hathi:~ $ aplay -Dhdmi:CARD=sofhdadsp,DEV=0 -vv /usr/share/ibus-typing-booster/data/coin9.wav ALSA lib conf.c:5671:(snd_config_expand) Unknown parameters CARD=sofhdadsp,DEV=0 ALSA lib pcm.c:2666:(snd_pcm_open_noupdate) Unknown PCM hdmi:CARD=sofhdadsp,DEV=0 aplay: main:831: audio open error: 無効な引数です
I don’t know what that means.
Check the output of "aplay -L". It'll list the possible device arguments. If you still get an error, try like
% aplay -Dhw:0,3 -vv foo.wav
thanks,
