Need assistance creating ANC workflow

HI all,

I struggling to build an ANC workflow in Sigmastudio on my ADAU1463 board.

Im sure im setting up the workflow wrong, as im also a little unsure as to how i should be connecting the pins to the MFxLMS filter.

Im making this project for use in a car, but i would like to do a test with a pair of headpgones and the mic bult onto the board before i delve further and get microphones. i have attached my project schematic.

currently my issue is that the MFxLMS filter will not do any learinging of coeffs, and i do not get any output from the mic when the mic is pinned to it, but when the mic is connected directly to the flow bypassing the filter, its working, so the filter is my problem, im just not sure how to go about doing it any assistance would be greatly appreciated!
