With pulseaudio 6.0 (wily), when you unplug headphones, pulseaudio
changes active port to Line Out, if plugged, or else to Speakers.
Speakers and Headphones will mute, when active port changes to something
else than respective port. Line out mixer level is not affected, when
active port is change to something else. Line out is effectively muted,
when headphone is plugged, and Auto-Mute Mode is set to "Line
Out+Speaker" in alsamixer. As for auto muting setting for speaker, when
headphone is plugged, I think auto muting speaker by pulseaudio is fine,
especially, as auto muting setting for Speaker does not work in ALSA
currently as noted above.

Title:
  Behaves inconsistently when you unplug headphones

Status in PulseAudio:
  New
Status in pulseaudio package in Ubuntu:
  Fix Committed

Bug description:
  In the beginning headphones are plugged in, and "Auto-Mute Mode" set "Disabled" in alsamixer.
  Start pulseaudio.
  Then unplug headphones. Speakers are muted.
  Then plug headphones in. Speakers are muted.
  Then unplug headphones. Speaker volume is unmuted.

  I expect Speaker levels and muted/unmuted state of Speakers in
  alsamixer stay intact when you plug headphones in or out. And
  concerning the Auto-Mute Mode "Disabled", Speakers should not get
  effectively muted when headphones are plugged in.
