Ubuntu 22.04 sound not working on new install

Question

I have no sound after a fresh install of 22.04 on https://amzn.eu/d/1erCTeT

At first I had "dummy input" only and the sound card was not detected

I have updated the kernel to latest with using mainline and upgraded/updated apt

I have tried ubuntu 22.04 audio output not working (dummy audio) to add the line options snd-hda-intel model=generic to /etc/modprobe.d/alsa-base.conf

and

Sound card not detected - Ubuntu 20.04 - sof-audio-pci to change the /etc/default/grub lines to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash snd_hda_intel.dmic_detect=0"
GRUB_CMDLINE_LINUX="intel_iommu=on,igfx_off"

this has allowed something to be detected:

~$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 3: Generic Digital [Generic Digital]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

and alsamixer shows this

pulseaudio now shows "Built-in Audio Digital Sterio (HDMI)" as the only output device but still no sound from speakers or headphones

Edit:

Some more information:
