> Just to let you know my findings since two years . There is a closed source kernel (in Linpus for Acer Aspire One) driver to handle this kind of small array microphone from Fortemedia (here on Acer Ferrari One 200).
 There are in fact 4 channels ie 2 stereo signals (force channels_max to 4 in hda_intel and patch_realtek).

it is possible to perform multi channel capturing when auto Mic and alt_capture are disabled by implement multi_in_xxx (open prepare and close ) similar to multi_out_xxx functions with the new generic parser
