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_Side

Paulo, maybe you can run these commands to switch between linein/lineout modes:

   # wget

http://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 0x40

Thanks, Fengguang

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.
