Line in Audio Sound reactive

ive been trying to get a pmod I2S2 working with WLED. I use an ESP32 on a AZ-Delivery board with the 19 pins on each side. I have no output on the LED Stripes. Has anyone got this combo to work, or a plan for the wiring? I also dont know how to specify the mclk pin. Ive used this as a source:Digital Microphone Hookup · atuline/WLED Wiki · GitHub

Look for pinout here WLED-ESP32-dev-board/Shields/Linear_audio_input_shield at main · srg74/WLED-ESP32-dev-board · GitHub
