combo mic/headhone jack

Anyone have any experience getting one of these jack sense combo in/out 1/8" jacks to play nice with ardour…or maybe jackd I suppose?

I’m running

Audio device [0403]: Intel Corporation 7 Series/C210

on this laptop and I cannot get it to use the jack as a input to save my life. I thought putting

options snd-hda-intel model=laptop-dmic

in my alsa-base.conf might work but so far, nothin’. Anyone have any ideas?
