Acer aspire5 N20C5 no sound kernel 6.6 and Intel Tiger Lake-LP Smart Sound Audio

after initial cinnamon install I had only “dumby” audio.
I have since installed the sof-audio-pci-intel-tgl module via a package and then I installed manjaro-pipewire.

But I have no audio through the build in speakers.

Not sure what I did wrong or what wrong path I might have taken from all the posts that leaves me with still no sound.

does anyone have some specific advice for this model of acer aspire5? Should I be using that module or some generic intel one?

did notice

but that is 6.9. Maybe I just need to upgrade my kernel further?

Latest Cinammon ISOs (released Sep 2023) use PulseAudio as default sound server and do not include sof-firmware that provides sof-audio-pci-intel-tgl driver

Kernel 6.6.19 has the same patch as later kernels so changing kernel or using a modprobe model option is not likely to help
