USB card pin to DAC ribbon HELP! - designations

I have a new DAC that runs by Bluetooth only - it has no USB card. I got a new card. The pins are different by only one pin.

Which one is it? Can you tell if the two pics are shown?

The LDAC pin. I never heard of that one before now but it is one of only five pins needed by the DAC.

The question is which pin on the USB card is the correct one for the LDAC pin coming from the DAC.
