Here is the problem. Pin 36 can't be routed to recording. It is an
analog speaker input pin.

Try this:
hint.hdac.0.cad0.nid36.config="as=0"

Or instead you can try this kernel patch:
Index: sys/dev/sound/pci/hda/hdac.c
===================================================================
--- sys/dev/sound/pci/hda/hdac.c        (revision 221156)

_at__at_ -2688,6 +2688,9 _at__at_
        case HDA_CODEC_AD1989B:
                beeper = 26;
                break;
+       case HDA_CODEC_AD1986A:
+               beeper = 36;
+               break;
        case HDA_CODEC_ALC260:
                beeper = 23;
                break;
. If it helps, show me the new dmesg.
