You have line in jack and internal mic, but power setting are D3 instead
of D0
You need to file upstream bug report
It is strange that mic phantom jack is created instead of internal mic
phantom jack

Title:
MBP 8,2 internal microphone stopped working
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
The internal microphone doesn't work in a Ubuntu Xenial installation.
The concrete model is Cirrus Logic CS4206. I've tested with the Xenial
live usb (2nd beta) and it doesn't work either, so it doesn't look
line I've broken something. However with the Wily live CD (both
standard Ubuntu and Kubuntu) it works.
