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 ?
I was testing using a browser on a youtube video. When I apply the changes, I lose the sound (pulseaudio gets killed), that message appears and I have to refresh the page to get sound again - but nothing changes.
Can you post the output of alsa-info.sh after you patched the line out
jacks
?

Which node is the headphone spdif combo jack ?
Using hdajacksensetest I found out the mapping: SPDIF port (jack 1): Pin 0x16 (Green Line Out, Rear side) jack 2: Pin 0x18 (Green Line Out, Rear side) jack 3: Pin 0x15 (Green Line Out, Rear side)
Do both headphone jacks have headphone , headset or line out icon ?
You can see the icons here [0] at page 20
Do you mean switch to 5.1 profile in sound preference is not enough ?
By listening on Youtube I can't hear the center and subwoofer without modifying the pulseaudio conf

If your specifcaion and user guide does not mention the support of surround 5.1
You need to find out the internal subwoofer use both channel or just left or right
speaker-test -c4 -t wav -D hw:0,0
If you hear high frequency from subwoofer, this mean you need software low pass filtter
Two headphone jacks, internal speaker and subwoofer
