Problems and fixes

Fix for I2S.h not found
Downgrade esp32 by espressif to 2.0.17.
(Web Ide did not have this problem)

Selecting huge app in partition scheme not possible using
Doit esp32 Devkit v1, use another similar device.

Could not compile due too : ( I have no fix! )

Current platformio.ini (same dram error as above)

Edit:
Lolin S3 Pro worked for me

It seems that Espressif re-wrote the Arduino i2s library for v3 of the esp32 Arduino framework.

From their Migration Guide

The I2S driver has been completely redesigned and refactored to use the new ESP-IDF driver. For more information about the new API, check I2S.

To get this work using the latest IDF and espressif libraries the all that was required was to update the i2s driver import to the new name <ESP_I2S.h>, set the pins using the new i2s.setPins() function, and finally the call to write to the i2s bus now needs to read from an 8bit buffer, so each sample needs to be either broken into two bytes and send in a array (I did this) or otherwise typecast the sample to be treated as a byte array.

Here's what I have for setting up the i2s driver

#include <ESP_I2S.h>
I2SClass i2s;
const int sampleRate = 22000;  // sample rate in Hz

void setup() {
  keypad.setDebounceTime(0);

  //setup I2S pins
  // i2s.setPins(I2S_PIN_BCLK, I2S_PIN_WS, I2S_PIN_DOUT);
  i2s.setPins(6, 7, 5);

  // New i2s driver defaults to PHILIPS MODE when in STD mode, and will automatically
  // fill both slots (ie left + right) with the same sample when using I2S_SLOT_MODE_MONO
  if (!i2s.begin(I2S_MODE_STD, sampleRate, I2S_DATA_BIT_WIDTH_16BIT, I2S_SLOT_MODE_MONO)) {
    Serial.println("Failed to initialize I2S!");
    while (1) { } ;
  }
}

And then inside of loop() I updated the writing to i2s to this

    ...

  int sample = tracker.UpdateTracker();

  // New i2s only wants to write bytes out, so we need to split the sample before writing
  // Copy the high and low bytes of our 16bit sample into a buffer and write that
  byte outbuf[2];
  outbuf[0] = lowByte(tracker.sample);
  outbuf[1] = highByte(tracker.sample);
  i2s.write(outbuf, 2);

    ...

Thanks so much!! I was going to investigate the upgrade this week but you’ve done all the hard work! The 8 bit buffer is actually a really good change as I’m adding custom sample support through littleFS (push samples from web to esp32 over web serial) and it’s much easier to deal w bytes. I’m going to change the sample converter to support 8 bit byte arrays and push changes to the OS in a couple of days. I really appreciate the help! -R

Updated the main to include your fixes! Much appreciated.
