Now I tried your Hdmi.conf. Again, seeing black screen for a couple of reboots. Kept trying -26 v4 kernel. Then maybe the 3rd or 4th time, it booted. Here are more info for this case.

No sound. Seeing Dummy output in pavucontrol.

By the way, alsa-mixer seems to select "HDA Nvidia" as the sound card. I don't think that should be the default.

inxi -Ax
Audio: Device-1: Intel Cannon Lake PCH cAVS vendor: Hewlett-Packard driver: sof-audio-pci bus ID: 00:1f.3
           Device-2: NVIDIA TU106 High Definition Audio vendor: Hewlett-Packard driver: snd_hda_intel v: kernel
           bus ID: 01:00.1
           Sound Server: ALSA v: k5.4.0-26-generic

Ideally, I think Device-1 above is the one that drives the laptop's speakers?
