Comment # 5 on bug 967156 from Takashi Iwai

The BIOS doesn't provide the proper pin configs for your docks.
Try to pass
  model=,tp410
option to snd-hda-intel, e.g. create /etc/modprobe.d/50-alsa.conf file
containing the following line:

options snd-hda-intel model=,tp410

Note that the comma before "tp410" is no typo.  It means to specify the second
entry.
