Sound disappearing ("Dummy output") on any kernel above 5.15, Dell XPS 17

so I'm regularly having some sound problems with my Dell on kernel updates, but the latest one (when pipewire was introduced) completely baffles me, as I really have no clue what to do any longer.

Yes - it works fine on the older kernels, but I can't stay on 5.15 forever because of other features. Distro-wise, I've tried to make it work on 22.04, 22.10 and now 23.04, but no luck with any of them.

Here are the diagnostics, and below is the list of things I've tried.

What I've tried was (update number 3):

1. Blacklisting snd-intel-dspcfg in modprobe
2. Killing, restarting, deleting and reinstalling pipewire, sof, alsa, ucm
3. Adding option snd_hda_intel.dmic_detect=0 to both modprobe and grub
4. touch /usr/share/pipewire/media-session.d/with-pulseaudio followed by a restart
5. Removing timidity
6. Adding options snd-hda-intel model=generic to modprobe
7. Installing linux-modules-extra
8. Looking into snd-hda-intel driver dependencies (all were installed)

That last thing was actually the only thing that lead to any change, as the "Dummy output" in the Settings changed to "HDMI/Display port" (connecting to my computer via HDMI or Bluetooth produces sounds), but that change had no effect on anything else.

I've been reading dozens of topics here for two days now, but no luck. Any help would be greatly appreciated!
