> The NID (what does it stand for?) of interest for the jack's output is
> indeed 0x16.
>
> When headphones plugged into docking station jack:
> $ sudo hda-verb /dev/snd/hwC1D0 0x16 GET_PIN_SENSE 0
> nid = 0x16, verb = 0xf09, param = 0x0
> value = 0x80000000
>
> When not plugged:
> $ sudo hda-verb /dev/snd/hwC1D0 0x16 GET_PIN_SENSE 0
> nid = 0x16, verb = 0xf09, param = 0x0
> value = 0x0
>
> GET_PIN_SENSE for 0x19 is 0x80000000 when headset with mic is plugged into
> dock.
> Pin sense of 0x19 does not change to 0x80000000 when only plugging 3pole
> speaker cable.
> Therefore, I assumed that 0x19 is the dock mic input (turned out later to
> be true).
>
> I installed alsa-tools-gui and used hdajackretast to override the pin
> config.
> It took a while to find out that not all changes are immediate (early
> patching and restart required).
>
> Using the early patching values from above, the sound is being redirected
> from the internal speakers to the dock jack, when headphones are connected.
> [When connecting an additional speaker to the left jack on the notebook,
> the sound is output to both dock and notebook jack.]

Do you mean the driver allow 4 channels play cannot get surround 4.0
playback when model=lenovo-dock is used ? (i.e. channels_max is incorrect )
