This is from model=ref. I can see it defines Line In as the
pin 0xe (exactly the jack marked as mic in the Vostro 1400).
This is how it should be.

Node 0x0c [Pin Complex] wcaps 0x400181: Stereo
  Pincap 0x00001737: IN OUT Detect Trigger ImpSense
    Vref caps: HIZ 50 GRD 80
  Pin Default 0x0181304e: [Jack] Line In at Ext Rear
    Conn = 1/8, Color = Blue
    DefAssociation = 0x4, Sequence = 0xe
  Pin-ctls: 0x20: IN VREF_HIZ
  Unsolicited: tag=04, enabled=1
  Connection: 1
     0x03

----------------------------------

This is from model=dell-3stack. There is no Line In defined. This
is the problem....


Node 0x10 [Pin Complex] wcaps 0x400181: Stereo
  Pincap 0x00000037: IN OUT Detect Trigger ImpSense
  Pin Default 0x01813050: [Jack] Line In at Ext Rear
    Conn = 1/8, Color = Blue
    DefAssociation = 0x5, Sequence = 0x0
  Pin-ctls: 0x20: IN
  Unsolicited: tag=04, enabled=1
  Connection: 1
     0x04


The question is: how can I use hda-verb to make pin 0xe
be an input pin (0x20), the way it were when using model = ref?

set PIN_IN mode:
        hda-verb /dev/snd/hwC0D0 0x0c SET_PIN_WIDGET_CONTROL 0x20

The node is 0x0c, but I am not sure if it is that simple.

Thanks.
