The lenovo sandy bridge notebooks (T420, T520, L520) didn't work with the external sound input and output connectors on the dockig unit (tested with P/N 45N5887).

Loading snd-hda-intel with model=thinkpad solved the problem so I added the accordings quirks to perform that decision automatically for these specific models.

Could you check whether model=auto with the latest kernel work? Basically I won't take any more the model-specific quirk but move all to the auto-parser as much as possible.

I just checked with upstream v3.1-rc10, model=auto didn't solve the problem on the Lenovo T520.

OK, so it's a bug of BIOS. BIOS doesn't provide the pin for docking-station.

The right fix in this case is to provide the pin config table. In sound git tree, there is a fix for Lenovo X200. A similar entry would work for you. git://github.com/tiwai/sound.git Check either topic/hda, for-next or master branch.

Here are some dmesg output with model=auto:

I will attach the codec#x files from /proc/asound/PCH if you need this information.

At best, please give alsa-info.sh output (run with --no-upload option).

thanks,
