Title:
  After unplug headphones and plug them again no sound can be heard

Status in pulseaudio package in Ubuntu:
  Confirmed

Bug description:
  After startup with headset plugged in they play sound nicely - no
  issue. When they are unplugged, the sound is switched to the speaker
  (laptop) - all good. However, when I plug the headset back there is no
  sound. I see the app on pavucontrol, the volume is fine - everything
  looks fine except there is no sound. I dumped output of "pactl list"
  command on startup (headset plugged), after unplugging the headset,
  and when it is plugged back. From the comparison of these outputs, it
  looks like the source has got muted after the headset is plugged.

  Source #1
  	State: RUNNING
  	Name: alsa_input.pci-0000_00_1f.3.analog-stereo
  	Description: Built-in Audio Analog Stereo
  	Driver: module-alsa-card.c
  	Sample Specification: s16le 2ch 44100Hz
  	Channel Map: front-left,front-right
  	Owner Module: 7
  	Mute: yes

  Attached three outputs:
  headset-in.txt - after startup with headset plugged - all fine.
  headset-out.txt - after unplugged headset - sound through the speaker - all fine.
  headset-back.txt - after plugged headset back - no sound.

  Any help greatly appreciated.

  Regards,
  Roman
