Thread:CircuitCo talk:Audio Cape RevB/Eagle Design Files - error with schematic

I'm currently involved in a project that requires me to record multiple channels of audio. I was going to jump the unused pins out the TLV320AIC3104 to another board and attempt to map them in my device tree overlay.

In an attempt to check which audio inputs the cape is using I consulted the schematic to find that pins 14 and 16 of the TLV320AIC3104 are being used which are LINE2L and LINE2R respectively. However when I compare that to the board design file I can clearly see that PINS 10 and 14 are actually being used which are LINE1LP and LINE2L. It would appear that PIN 16 (LINE2R) dead ends. Now I am really confused as I would expect LINE1 L&R to be together and LINE2 L&R to be together.

If anyone could explain what I am missing or if there really is an error that would be appreciated.
