You have to file upstream bug report

You have front headphone jack and headphone playback switch but no
headphone playback volume

 This mean that headphone and green line out share front playback volume
control

Title:
  Sound is not automatically switched back from headphones to speakers

Status in pulseaudio package in Ubuntu:
  Incomplete

Bug description:
  When plugging in headphones, sound output is correctly switched from
  speakers (line out) to the headphones. When the headphones are
  unplugged, sound is NOT automatically switched back to the speakers.

  This bug started happening on my system after I upgraded from 14.04 to
  15.10 so it is a regression. Attached is pulseaudio log of what
  happens when I plug and unplug my headphones.
