Fresh install no sound (laptop) Alder Lake PCH Audio

I might be the millionth person with this problem but here goes…
I’ve done a fresh install and am not getting any sound from my laptop. LiveCD worked.
I should add, if I plugin a USB-C earphone with microphone, it works fine.

I’ve tried installing sof-firmware, lts/zen kernel and I’m still getting nothing.

Here’s the inxi -Fxxxza --no-host output

It seems that with this hardware there have been a number of users with the same issue.

I can’t seem to find a good solution. Any suggestions?

None that have worked on this one.

While reading, somewhere I found that switching to latest Kernel may help. Along with this, using latest version of firmware-sof-signed was the recommended tips.
What is your take according to your knowledge ?

For kernels, tried: base kernel 5.17.5 - 5.17.7, linux-zen 5.17.5 - 5.17.7, linux-lts 5.15.39
Firmware-sof is installed (not sure about firmware-sof-signed) but no dice, unfortunately.

.
Somewhere here, it is written that kernel is trying to use wrong module.

Why don’t you switch your sound server to PulseAudio and see if it works? You can use this guide from :enos: wiki.

Remember to restart your computer after switching to PulsAudio.
