Do your dock station has one headphone and one mic Jack or just one combo headset Jack ? Connect headphones or a headset that has a 3.5-mm (0.14-inch), 4-pole plug to the audio connector to listen to the sound from the computer.

The Docking station as well as the Notebook has just one Stereo/Mic Combo Audio Jack. I've tried various Headset with 4-Pole and 3-pole plugs. They all work fine on the Notebook but not with the Docking station (40A20090EU). However the Laptop speakers mute as soon as I plug the Headset in the Docking Station so it seems that the driver is somehow aware of it!

Remove the following lines options snd cards_limit=1 #options snd-hda-intel model=thinkpad options snd-hda-intel model=thinkpad enable=1 index=0 options snd-hda-intel model=hdmi enable=1 index=-2

I already tried that no success. Without the index parameter alsa switches to the HDMI output by default.

lenovo-dock expect dock headphone Jack and dock Mic Jack ?

I guess so since there is only one plug. Again all works well when I use the Notebooks 3.5mm plug.

Well here I have another problem. The script doesn't get very far: ALSA Information Script v 0.4.62 --------------------------------

This script visits the following commands/files to collect diagnostic information about your ALSA installation and sound related hardware.

dmesg lspci lsmod aplay amixer alsactl /proc/asound/ /sys/class/sound/ ~/.asoundrc (etc.)

See 'alsa-info.sh --help' for command line options.

cat: /proc/asound/modules: No such file or directory

Strange thing, /proc/asound exists: HDMI PCH card0 card1 cards devices pcm timers version

I've compiled the drivers als modules and they are loaded!

Any further help?

I created the output you requested (Lenovo ThinkPad T440p in UltraDock, no sound when docked via dock jack but notebook speakers are also mute).

not docked: http://pastebin.com/MFQT3R9S docked, no headphones: http://pastebin.com/8UN1sHSM docked, headphones plugged in dock: http://pastebin.com/7XauZLZz docked, headphones plugged in notebook: http://pastebin.com/xfL5qkge

Based on that, can you help us getting sound to work on the dock?

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 á 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

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...

1. 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

2. 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

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
