Alright, I think I found the correct settings:

[codec]
0x10ec0292 0x17aa220c 0

[pincfg]
0x16 0x21211010
0x19 0x21a11010

If
a) no headphones plugged in anywhere, laptop speakers work
b) headphones only plugged in dock and not at laptop, dock headphones 
work, laptop speakers silent
c) headphones plugged in laptop (and/or dock), only laptop headphones 
work, laptop speakers and dock headphone silent

If this is the intended behavior, these values work.
