Well, I was able to get audio, but it's extremely quiet. My updated settings are: typedef enum { SR_8K = 8000, SR_11K = 11025, SR_16K = 16000, SR_22K = 22050, SR_44K = 44100, SR_48K = 48000, SR_88K = 88200, SR_96K = 96000, SR_176K = 176400, SR_192K = 192000, SR_352K = 352800, SR_384K = 384000 } samp...

You may be right, I will try connecting as MCLK and try it out.

I'm trying to get valid audio data using an ESP32-S3 and the IM69D130 Microphone Audio Shield2Go Platform Evaluation Expansion Board (https://www.infineon.com/dgdl/Infineon-IM69D130_Microphone_Shield2Go-GS-v01_00-EN.pdf?fileId=5546d462677d0f4601677f3486ed0941). This board has two IM69D130 microphone...
