sorry, this is beyond my skill, and I didn't find a guide to follow. 
Maybe you can give me a little bit more precise instructions on what to do with 
the values. 
I think I found the relevant part of the windows .inf file (Section starting 
with [CDB4206DM12PinConfigOverride]), i think I have to switch the bytes e.g. 
0x1,10,1c,97,00 will become 00 97 1c 10 and I found a guide describing what 
those hex digits mean (comment #15 on 
http://www.insanelymac.com/forum/topic/275086-pin-config-patching-voodoohda-0272-project-os-x-branch/)

the info retrieved from the pins matches with the comments of the
windows .inf file.

But now? What do I do with these hex codes. Which of these and where do
I have to patch my audio driver to recognize the TRRS input signal?
