you need to use debug version of alsa driver to check the system log to
find out whether your codec alc292 can automatcally  differentiate
headset and headphone as your thinkpad does not support conventional mic

Title:
  [20ALCTO1WW, Realtek ALC292, Black Mic, Left][Lenovo ThinkPad X240]
  external mic has no sound at all

Status in HWE Next Project:
  Incomplete
Status in alsa-driver package in Ubuntu:
  Confirmed

Bug description:
  During this test, an error dialog was thrown, reading:

  The following mixer control(s) might be incorrectly set: 
  Mic is at 0.0%

  Mic is muted
  Please try to fix that (e g by running 
  "alsamixer -D hw:PCH" in a terminal) and see if that solves the problem.
  Would you like to continue troubleshooting anyway?

  However, the System Settings... -> Sound UI shows the mic as not
  muted. When I tried running the alsamixer command, I saw mic and mic-
  boost were both showing 0; I cranked them up to 100, but it made no
  difference. I also tried re-running this command with the mic/mic-
  boost still set to 100 and it threw the same error.
