Thank you for reviewing this. I have made adjustments as suggested. Revised patch attached.
   

The chain_id may appear odd, I can assure you that it does the job. I picked up the suggestion from the excellent Arch Linux wiki:

https://wiki.archlinux.org/title/Intel_NUC#Hades_Canyon_NUC_-_No_External_Microphones

So my patch equates to:

a) creating a fixup for enabling spdif

and

b) making the new "model=nuc-hc" equate to the spdif fix + "model=dell-headset-multi"

I hope this is acceptable. As stated, I have used this solution for half a year or so.
