Hey Raymond!
Sorry for the late reply! I had trouble following your input as I am not experienced with this. "HD-Audio.txt" helped a lot!
To make a 5 hour story short, this is my result: Using early patching, everything works to my linking: 0x16 0x2121101f # dock headphones 0x19 0x21a11030 # dock mic
Thank you very much for your help!
I guess that building a patch รก la ALC269_FIXUP_LENOVO_DOCK is not a big deal, but not my business. If wanted, I can do testing, as soon as I learn how to properly compile and install a custom kernel.
I'll post something on https://github.com/leoluk/thinkpad-stuff/wiki/Haswell-ThinkPad-problems to tell other people how to fix this right away.
More to my story: I found /sys/class/sound/hwC1D0, which is a Realtek ALC292 device. 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.] When connecting a mic to dock, the dock mic shows up as input and is used as such. When only connecting a headset without mic, the internal mic stays functional.
Best, Bernhard

the headphone is at node 0x15
control.16 { iface CARD name 'Headphone Jack' value true comment { access read type BOOLEAN count 1 } }
you need to use hda_jack_sense_test.py which require python and hda codec parser of hda-analyzer to find out
https://bugzilla.kernel.org/show_bug.cgi?id=66621#c39
pd=1 when plugged and pd=0 when unplugged
or hda-verb GET_PIN_SENSE
https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/plain/Documenta...
- the node of the headphone of the dock headset
node 0x16 , 0x18 and 0x19 which pincap support output
try hdajackretask or early patching to fix the pin default to dock headphone
- for the dock headset mic , you need to find by trial and error from
the remaining unconnected nodes which pincap support input
node 0x13, 0x19, 0x1b, 0x1d
https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/log/sound/pci/h...
0x21a11000 /* dock-mic */
need to set bit 8 if dock headset mic use jack detection of headphone instead of jack detection of its own pin compex
0x2121103f /* dock-HP */ 0x21440100 /* dock SPDIF out */
you need to clear bit 8 if pincap of node 0x1e support DETECT
