I have Ubuntu 24.04.1 LTS on a Dell XPS 9320 (not dual-boot). Since I upgraded from 22.04 last month, my internal speakers have not worked. In Settings, Sound Output lists "No Output Devices". I do get sound via USB devices (speakers or earbuds). I've tried many suggestions from many related questions (see below), but none have worked. Now I'm reaching out for help (please and thank you). From my reading of the related questions, here's relevant information for my case.
Based on remarks of V1del, a forum moderator at archlinux. I tried the following 4 commands to diagnose:
$ sudo fuser -v /dev/snd/*
USER PID ACCESS COMMAND
/dev/snd/controlC0: jim 2555 F.... wireplumber
/dev/snd/seq: jim 2549 F.... pipewire
$ aplay -l

$ pactl list cards
Connection failure: Connection refused
pa_context_connect() failed: Connection refused
$ sudo pactl list sinks
Connection failure: Connection refused
pa_context_connect() failed: Connection refused
I guess the two "Connection failure" are a problem, but I don't know what they mean.
Based on my research the past few weeks, the following also seem relevant to diagnosing my problem.
$ lspci | grep -i audio
00:1f.3 Multimedia audio controller: Intel Corporation Alder Lake PCH-P High Definition Audio Controller (rev 01)
and
$ inxi -A
Audio:
Device-1: Intel Alder Lake Imaging Signal Processor driver: N/A
Device-2: Intel Alder Lake PCH-P High Definition Audio
driver: sof-audio-pci-intel-tgl
API: ALSA v: k6.8.0-48-generic status: kernel-api
Server-1: PipeWire v: 1.0.5 status: active
I don't see a sound problem in that output (the Device-1 line makes sense, as my camera doesn't work (Cheese, Skype); but that is not my focus here). I do see a problem from the next command I tried
$ sudo dmesg | grep -i snd

When I google "SDW0-Capture: ASoC: error at snd_soc_link_prepare on SDW0-Capture: -61" I see many posts (often Archlinux) that talk about downgrading the kernel. I don't know what that is, and it sounds bad (like a duct-tape fix, a patch not a fix). But maybe useful to note my kernel:
$ uname -r
6.8.0-48-generic
Please note that pipewire seems fine:
$ systemctl --user status pipewire

I think wireplumber's only problem is with the camera:

Maybe this info about pipewire-pulse is relevant?

I got changes, but no fix, with the following:

In Settings (Sound Output), this turned "No Output Devices" to "Dummy Output" in the Output of Sound. It also changed the cards and sinks listings, as follows:

Thank you in advance to any kind soul who can help me restore my speaker sound. And I'd be happy to share more info if it would help ...
PS If it helps, here is a sampling I other questions I've looked at for help:
Fixing No Sound (Dummy Output) Issue in Ubuntu 24.04 From the top answer there, I used sudo gedit to create /etc/modprobe.d/audiofix.conf and put in the lines
options snd-hda-intel dmic_detect=0
options snd-hda-intel model=laptop-amic enable=yes
After rebooting, no change.
No sound output devices listed after upgrade from 21.10 to 22.04 looks relevant, but it is about pulseaudio and 24.04 uses pipewire.
Fixing No Sound (Dummy Output) Issue in Ubuntu 24.04 suggests to downgrade the kernel, but that sounds bad to me. And my sound problem is "No Output Devices", not "Dummy Output"
I see several unanswered questions that may be about the same as mine, with no speaker-sound in 24.04; e.g. lenovo M90a, Ubuntu 24.04, missing sound on speakers, earphones ok
In my case aplay lists a sound card, so my problem differs from many other dealing with no sound in 24.04, such as No sound after upgrade from Ubuntu 22.04 to Ubuntu 24.04.
No sound in internal Speakers in Ubuntu 24.04 sounded promising, but the fix there was to disable fast-boot in Windows (I don't have Windows).
=== Here's more info,
tail "/etc/modprobe.d/alsa-base.conf"

I updated my bios to the most recent (from 2.10 to 2.16.1) but that seems not to have affected anything.
video card seems to be Intel

As suggested by @hynnema, I used Mainline to change kernels to 6.5.11 and added "options snd-hda-intel model=dell-headset-multi" to alsabase.conf and rebooted (kernel 6.5.11) but still No Output Devices in Sound Settings. But now pipewire has a problem:

I plan use Dell's system restore, but first I need to back up my data and my legacy software programs.
