If it is a netbook with one jack which can be used as headphone or mic

The best way is to measure the impedance of the jack to determince  HP or
mic and swtich pin ctls to OUT or IN as pincap support ImpSense

Node 0x14 [Pin Complex] wcaps 0x40018d: Stereo Amp-Out
  Amp-Out caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1
  Amp-Out vals:  [0x00 0x00]
  Pincap 0x0000003f: IN OUT HP Detect Trigger ImpSense
  Pin Default 0x0121411f: [Jack] HP Out at Ext Rear
    Conn = 1/8, Color = Green
    DefAssociation = 0x1, Sequence = 0xf
    Misc = NO_PRESENCE
  Pin-ctls: 0xc0: OUT HP
  Unsolicited: tag=00, enabled=0
  Connection: 1
     0x0c

Try

hda-verb  /dev/snd/hwC0D0 0x14 SET_PIN_SENSE 0

hda-verb /dev/snd/hwC0D0 0x14 GET_PIN_SENSE 0

and check the returned values when you plug hp and mic are different
