kentb, thank you for the fix, this also works for me on an Asus N550JV.
This should be added in the kernel for 14.04 too

Title:
  [XPS 15 9530, Realtek ALC668, Mic, Internal] No autoswitch when
  headset is plugged in

Status in “linux” package in Ubuntu:
  Fix Released

Bug description:
  When a headset is plugged in (four-position plug with an inline mic)
  on a typical laptop, the inline mic is switched to by default and when
  the headset is unplugged, the system reverts to the internal mic. In
  this case, there is never a switch to the inline mic. The system
  internal mic stays active at all times.
