Realtek ALC885 Macbook Air microphones Linux

I ask your help regarding a possible pin configuration for the Apple Macbook Air 1,1 (Early 2008, A1237) microphones under Linux.


(I know this is a bit different from what you do here, but still your knowledge of Apple kext, etc. might prove useful.)


I put Linux on this machine, and everithing works fine, except for the microphones (the external is connected via a TRRS iphone-like jack, the internal is built in, near the camera).


I know (from http://www.insanelymac.com/forum/topic/220090-alc889a-pin-configuration/?do=findComment&comment=1554954 ) that OS X does something at node 0x27=39, which I don't see at all: so I'd like to ask you if you know possible pin candidates to be the mic on this machine, and possible coeff verbs or GPIO, etc. one should try to feed the codec, or maybe if in this case it is a node virtually implemented in the driver: anything you might know to make mics work under ALSA and Linux.


Thanks and best,
