   snd_intel_dspcfg: dsp_driver=1

   was a leftover from testing. I' ve removed all parameters, add added
   the debug options you've asked.

   Some googling reveals that others suffer from the same problen on the
   same laptop as well. Some report that the device appears after pci-bus
   rescanning however that did not work in my case so I agree there might
   be an issue with probing the relatek device. Unfortunately I'm not a
   kernel dev so I don't even know where to start looking however I'm
   happy to investigate with your help.

   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
