Isn't all that stuff defined in /proc/asound/card0/codec#0  ?    Maybe
it's just my intel HDA audio, but there is pin config information
defined there that says:

Node 0x0a [Pin Complex] wcaps 0x400181: Stereo
  Pincap 0x081c: OUT HP Detect
  Pin Default 0x0221401f: [Jack] HP Out at Ext Front
    Conn = 1/8, Color = Green
    DefAssociation = 0x1, Sequence = 0xf
  Pin-ctls: 0xc0: OUT HP
  Unsolicited: tag=30, enabled=1
  Connection: 3
     0x10 0x11* 0x17

Seems like there might be something for you that would detect whether
or not the laptop is connected to a docking station and then route
connections properly.  But like I said I have no idea if this is just
for intel HDA.
