Do you mean hdajackretask cannot shutdown pulseaudio or you still have
other applicaion using the sound card which prevent dynamic reconfiguration
of snd-hda-intel ?

Can you post the output of alsa-info.sh after you patched the line out
jacks ?

Which node is the headphone spdif combo jack ?

Do both headphone jacks have headphone , headset  or line out icon ?

The normal fix is to add back the missing headphone jacks

Do you mean switch to 5.1 profile in sound preference is not enough ?
