The use of this option is not clear:

snd_intel_dspcfg: dsp_driver=1

This means you are trying to force the use of the legacy driver. is this
intentional? Can you remove it and see what happens?

The results show you don't have a driver bound to the PCI device, so
likely something goes boink in the probe.

It wouldn't hurt to enable dynamic debug as well.

options snd_hda_intel dyndbg=+p
options snd_intel_dspcfg dyndbg=+p
