I am using an STM32F7 Nucleo Board with SPI/I2S to get audio data from this MEMS microphone.

I am having issues with none of the signals triggering: WS, CLK, or Data.
I call the HAL_I2S_Receive function, and neither the clock nor the select signal is triggered. I enter the timeout checker and only leave once I have timed out.
If anyone has any suggestions? I have my DAD connected, and I see nothing.
