Here is what I know:

  Node 0x10 = Internal speaker
  Node 0x12 = Mic/Line jack on laptop
  Node 0x14 = Headphone jack on laptop
  Node 0x16 = CD audio

In terms of nodes that is all I can be sure of because that's all I can
test.  I have no idea of what the dock does or how its jacks are mapped to
codec nodes because I don't have a dock to test with.

Having said that, I find it operationally odd that the internal speaker
would share a node with a line out jack on the dock.  Then again, it
wouldn't be the first time a laptop manufacturer has done something odd.

I've never fully understood the information provided in the codec proc
file.  In my (very limited) experience the output doesn't always match up
with the reality of the hardware.
