Analog microphone use from audio jack of STM32F412G-DISCOVERY Board

I am looking for help capturing (analog) audio from a microphone headset plugged into CN9 of the STM32F412G-DISCOVERY board.   I have no problem doing this with the MEMS microphones on the board, but have an application that requires use of the headset microphone instead.  I believe I have set all WM8994 registers properly to do this, but am still unable to solve the problem. 

Any suggestions, a help examples, or other guidance would be greatly appreciated.

Thanks in advance.

Show your settings.

Do you see analogue audio at  the CODEC input?
