Issue receiving PDM data in STM32L431KBU6TR

[Shivam1282]

I'm currently using MEMS MP34DT06JTR audio sensor with STM32L431KBU6TR Mcu. I'm facing issue in receiving PDM data through SAI/I2S. I have connected one microphone to SAI Block-1 and the L/R pin is grounded. I'm attaching the main.c file and the configuration I used for SAI Block below for reference. Also I've attached sai_data.png which shows the result I'm getting currently.
