Here are the Linux and WinXP pin configurations. Both Linux and WinXP configure node 0x0c as an output pin.
However the driver seems to be offering three schemes:

IDS_CONFIG_OPEN Speaker_Side/LineIn IDS_CONFIG_51 LineIn IDS_CONFIG_71 Speaker_SidePaulo, maybe you can run these commands to switch between linein/lineout modes:

The other models for this codec are for Dell computers. Probably, all of then will behave the same way, right?
I guess the hda-verb commands will work for all IN/OUT configurable pins.
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
ALSA defined the following values according to the HDA spec:
/* Pin widget control - 8bit */ #define AC_PINCTL_IN_EN (1<<5) #define AC_PINCTL_OUT_EN (1<<6) #define AC_PINCTL_HP_EN (1<<7) #define PIN_IN (AC_PINCTL_IN_EN) #define PIN_OUT (AC_PINCTL_OUT_EN) #define PIN_HP (AC_PINCTL_OUT_EN | AC_PINCTL_HP_EN)So PIN_OUT=0x40 and PIN_IN=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.
You can locate the external mic pin in /proc/asound/card0/codec#* and feed its node id to the hda-verb command. It should work the same way.
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.
But you pasted info for 0x0c instead of 0xe below... Would you provide the full codec file?

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

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?
Where is Node 0x0e? You didn't paste Node 0x0e info, but 0x0c and 0x10.
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.
It's trivial to try it out, its harmless anyway :) You only have to replace 0x0c with your mic node.
Thanks, Fengguang
