Hi Tobin,
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:
scheme desc 0xC dev
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:
# wgethttp://www.kernel.org/pub/linux/kernel/people/tiwai/misc/hda-verb-0.3.tar.bz...
# set PIN_IN mode hda-verb /dev/snd/hwC0D2 0x0c SET_PIN_WIDGET_CONTROL 0x20 # set PIN_OUT mode hda-verb /dev/snd/hwC0D2 0x0c SET_PIN_WIDGET_CONTROL 0x40Thanks, Fengguang

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.

----------------------------------
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?
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.
