Most notebook with dock station use 4 channel codec but there are three
outputs at different location

1) headphone, speaker, dock headphone
2) headphone, speaker, dock line out
3) headphone, speaker, dock speaker

If the audio output node contain the volume control and switch , two
outputs need to share the volume control

The name of the shared volume control are different for the above three
cases as the parser put two speaker
pins and two headphone pins of different location

In your cases the headphone and dock headphone also share the same
headphone playback switch in addition the headphone playback volume

Post output of pactl list

Can you select surround40 profile in sound preference ?

The front audio panel of some computer chassis does not support Jack
detection
