CircuitCo AudioCape and 4.4.6-bone-rt-r7 kernel, not quite there

I decided to try to get the CircuitCo audio cape up and running on 4.4.6-bone-rt-r7, because while similar, my cape has a few differences.

My DTB: http://pastebin.com/Wja7ZQRk
and DTBO: https://github.com/RobertCNelson/bb.org-overlays/blob/master/src/arm/BB-BONE-AUDI-02-00A0.dts

Results of speaker-test, aplay, etc.:

One possibility, ALSA is still not configured correctly for this cape, but I wonder if anyone has the right configuration for it?

Thanks!
