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
Are you sure that those icons and jacks order matched with your notebook ?
The user guide seem not specific to g751jm
3) the icon is a line out symbol, arrow point out of the circles but the description is audio input jack (i.e. line in) which does not match with the specification
Neither specification nor user manual mention the support of surround 5.1
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
