I get an include error when trying to include the <I2S.h> header file.
fatal error: I2S.h: No such file or directory

Here's the verbose output:

Here are the details of the device and software:
Board: ESP32_S3 Dev Module
Board Library Version: esp32 by Espressif Systems v3.0.1
Arduino IDE Version: 2.3.2
Platform: Windows10, x86-64

How do I resolve this ?

Hmm. A simple test of including the ESP32's platform library I2S using the same board type succeeded for me.

#include <I2S.h>

void setup() {
}

void loop() {
}

cli compile -b esp32:esp32:esp32s3 --warnings all --output-dir ~/tmp --no-color (in directory: /home/me/Documents/sketchbook/Firebeetle32/test)

Perhaps check in C:\Users\casli\AppData\Local\Arduino15\packages\esp32\hardware\esp32\3.0.1\libraries for the I2S directory and that it contains the src directory with I2S.h in it?

I checked the esp32\3.0.1\libraries\ directory and it doesn't contain a directory named "I2S". It does however contain a directory named 'ESP_I2S', which contains ESP_I2S.h. But I'm not sure it's the same thing, is it?

I just downgraded to esp32 version 2.0.17. It has the I2S header file (but doesn't contain the E2S_I2C library, so it's fair to assume that this one replaces the I2C library).
Problem solved! Thanks for your help @van_der_decken !!

This is because Arduino IDE abandoned the legacy I2S API, now using the new APIs (i2s_std.h/i2s_pdm.h/i2s_tdm.h), so they decided to update the .h to ESP_I2S.h.
