On a Colibri T20, the AC97 Codec WM9712 gets detected and I can play
audio after unmuting the right output:
amixer -c 0 set 'Left HP Mixer PCM' on
amixer -c 0 set 'Right HP Mixer PCM' on

Lucas, did you tried once to capture input? In my test using arecord -f
cd, recorded sound is very slow (rate problem?)
