Do you have the Realtek ALC1150 sound card?
Not sure it's the same issue, but I've spent many, many hours trying
to get my built-in sound working. Broke I think on 4.20, although I
can't say for sure it's a kernel issue.

Here are some forum posts I found, marginally related to my issue.
It's unbelievably frustrating to yield zero results for the hours I've
put into this problem. I don't know if it's BIOS or what, I even
booted back into Windows and even then it seems audio-out is broken.
Bluetooth audio works for me though, as does audio in via USB microphones.
Is this similar?

Hi
Does anyone know why my sound card may be listed as unavailable?
I got a built-in Intel sound device which is seen by pulseaudio.
In the volume control settings (pavucontrol-qt) I can select the configuration Analog Stereo Duplex (unplugged) (unavailable)
I don't know why it shows as unplugged and unavailable.
This is not a new situation but I remember a few years ago I could use this internal sound card just fine.
Thanks
Andy
