Hi,
are there any news on this?
I tested pin cfg 0x17 0x21211010 too. In general it looks good, but I can not hear anything.
Does anyone have some hints what can I do or test to get the sound working on Dock HP?
Thanks,
Best regards, Dennis
Hello,
I'm unable to get any sound from the Headphone Jack of a Lenovo Ultra Docking Station with a new Lenovo T470 connected. With a T440p however I get sound from the Docking Station Headphone Jack.
I did some research on my alsa configuration and found out that there is no pin configuration supplied from the Laptop BIOS that connects to the Docking Headphone Jack.
The hdajacksensetest tool only shows this when the Laptop is docked and a Headphone is pluged in: Pin 0x18 (Black Mic, Left side): present = No Pin 0x21 (Black Headphone, Left side): present = No
So I did some patchingOn 14.08.2017 11:36, Stefan Mark (JIRA) wrote: using a early firmware load patch floating around the web targeting the same docking station for my older T440p laptop: echo 0x17 0x21211010 > /sys/class/sound/hwC0D0/user_pin_configs echo 1 > /sys/class/sound/hwC0D0/reconfig
Now my Docking Station Headphone Jack is being detected! :)
With the Headphone Connected: Pin 0x17 (Black Headphone, Docking station, Rear side): present = Yes Pin 0x18 (Black Mic, Left side): present = No Pin 0x21 (Black Headphone, Left side): present = No
And disconnected: Pin 0x17 (Black Headphone, Docking station, Rear side): present = No Pin 0x18 (Black Mic, Left side): present = No Pin 0x21 (Black Headphone, Left side): present = No
However there is STILL no sound even after unmuting everything in alsamixer! I'm pretty sure 0x17 is the right pincfg but I'm not sure about 0x21211010 and how I obtain such an address for my laptop.
Could someone please help me out here or give me a hint?
Here is a alsa-info.sh dump when the Laptop is not connected to the Dock: https://pastebin.com/eTNnfnzL

I'm sure I'm very close. But something is still missing. Any help is much apprechiated!
Thanks in advance Dieter
