Hi all,
for new Lenovo Thinkpads (mine T530, will probably affect all new [TXW][45]30 models), the model=thinkpad module option does not enable the speaker jack of the docking station. Sound works perfectly with the laptop, only the docking station needs extra work. I managed to get it work using hda-analyzer. It produced the following diff:

Unfortunately, I failed to create a working hda-verb script. I can change the out-pin with:
hda-verb /dev/snd/hwC0D0 0x1b SET_PIN_WIDGET_CONTROL 0x40
but I did not find the command to unmute the channel. Can anyone tell me which options are necessary and can this easily be fixed in the kernel?
Also, hda-analyzer showed me two mixer devices, they produce a slightly different sound. I don't know if this is important.
Thank you very much! Mario
