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 ...

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 ...

I'm currently using an ESP32-S3 to connect to a PCM1808 Audio ADC (https://www.ti.com/lit/gpn/pcm1808). The standard i2s example seems sufficient with one exception, the SCLK. The PCM1808 part requires a clock input which is it's sample clock:
