you have to provide verbose pulseaudio log

do you mean Mic is switch between internal Mic and dock Mic since
external Mic is unplugged ?

driver and pulseaudio need to check both  ext Mic and dock Mic to decide
the Mic selection

Title:
  [HDA-Intel - HDA Intel PCH, recording] Clipped audio output added to
  mic recording when docked

Status in “pulseaudio” package in Ubuntu:
  New

Bug description:
  Hi,

  I have a Lenovo X220 with an mini dock series 3 plus.  Ever since I
  have been using Ubuntu (originally 12.04 and more recently a clean
  14.04 install) I have issues with recording sound from the docking
  station.

  To elaborate plugging the devices in as follows works as expected:
  Mic into docking base
  Headset into laptops headset socket (a combined headset/mic socket)

  However when I connect both the headphones and the mic to the docking
  base a garbled representation of the output audio is mixed with the
  otherwise good quality input.

  I have tried to demonstrate this during the bug report process.  I had
  music playing during the sound recording tests.  During the first test
  the music playback stopped on its own and good quality sound was
  recorded.  During the second test music resumed and I talked over it
  at the end...  Hopefully this helps clarify my explanation.

  Alan
