[sound] Intel Tiger Lake Output device not recognised anymore by Pulse

Hello all, as per title: this worked from day one and never had any issue through Pulse.
I recently did a few system upgrades and now I don't get any more sound from the on-board sound chip.

lspci lists the following:

$ lspci | grep -i sound
00:1f.3 Audio device: Intel Corporation Tiger Lake-LP Smart Sound Technology Audio Controller (rev 20)

few more outputs:

$ sudo dmesg | grep -i sound

$ sudo dmesg | grep -i audio

Gnome sound config panel shows "No output devices".
I have installed pavucontrol and it currently lists only HDMI/Displayport output (as unplugged).

The input mic works without problems (which could be unrelated anyway).

Re: [sound] Intel Tiger Lake Output device not recognised anymore by Pulse

sudo fuser -v /dev/snd/*
aplay -lL
pactl list cards
pactl list sinks

generally speaking either kernel or sof-firmware or both, you could as a test try downgrading the kernel to a 6.3.x variant or test behavior on linux-lts and/or a downgraded sof-firmware.
