Thanks a lot, Fengguang.

The other models for this codec are for Dell computers.
Probably, all of then will behave the same way, right?

I still have a question. I see that you  changed Pin Default 0x01113014,
for 0x01813021, in the driver for having LineIn.
Also, Pin-ctls: 0x40 should provide the pin as an output. The Node is 0x0c.

Therefore,

# set PIN_OUT mode
       hda-verb /dev/snd/hwC0D2 0x0c SET_PIN_WIDGET_CONTROL 0x40

 makes sense.

But how would I know that 0x20 would turn the pin 0x0c into LineIn?

  # set PIN_IN mode
       hda-verb /dev/snd/hwC0D2 0x0c SET_PIN_WIDGET_CONTROL 0x20

I am asking because I have a Dell laptop (Vostro 1400) where the external
mic
works when I use model=ref (and I loose the speakers in this case), but not
when I use model=dell-3stack. If I could figure out how to switch
the pin using hda-verb in this case, would solve my problems when using
skype.
