USB card pin to DAC ribbon HELP! - designations

[egbc]

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.

You dont get any sound or whats the problem?
You jest connect:
Gnd-gnd
Mclk-mck
Fsclk-lrck
Bclk-bck
Data-data

I dont see ldac pin on any of photos you attached
If you dont have ldac pin on another board it shouldnt be left floating, you connect it ground

Fsclk is the answer. I wanted confirmation first. Thanks for the confirmation.
