[alsa-devel] No sound on Thinkpad T440s in Docking Station

Hello Takashi,

thanks for the patch. I have tested it and found the following strange 
behavior: I only get sound from the dock headset port if I also plug in 
a headset to the laptop headset connector.

Thus I reverted to my original kernel module + firmware patch and did 
some further testing. The results is as follows:

a) Using:
------------------
[codec]
0x10ec0292 0x17aa220c 0

[pincfg]
0x16 0x2121101f
0x19 0x21a10030
------------------
I get LOW VOLUME sound from the dock headphone ONLY when also laptop 
headphone connector is plugged in.

b) Using:
------------------
[codec]
0x10ec0292 0x17aa220c 0

[pincfg]
0x16 0x2121101f
0x19 0x21a10030
0x1b 0x2121101f
------------------
I get HIGH VOLUME sound from the dock headphones when no laptop 
headphones are connected, but LOW VOLUME sound when both are plugged in.

The output of
# hda-verb /dev/snd/hwC1D0 0x1b GET_PIN_SENSE 0
nid = 0x1b, verb = 0xf09, param = 0x0
value = 0x0

stays the same for any headphone configuration (only dock, only laptop, 
both).

So I do not quite understand whats happening...
