i2s to i2s doesnt work - noise - INMP441 to MAX98357a

[RenanEspinar]

Hello everyone.
I was trying to test some code from this project.
I realized that the code STREAMS I2S - I2S and STREAMS I2S - I2S 2 does not work.
This is my hardware:

• ESP32 - WROOM -32 ESP32S 32 PINS
• INMP441
  PIN 25; -> WS
  PIN 33; -> SCK
  PIN 32; -> SD
• DFROBOT MAX98357a
  PIN 14; -> LRC
  PIN 15; -> BCLK
  PIN 18; -> DIN
  ALSO my code is this:
  `#include "AudioTools.h"

AudioInfo info(48000, 1, 16);
I2SStream in;
I2SStream out;
StreamCopy copier(out, in); // copies sound into i2s

// Arduino Setup
void setup(void) {
// Open Serial
Serial.begin(115200);
// change to Warning to improve the quality
AudioLogger::instance().begin(Serial, AudioLogger::Info);

// start I2S in
Serial.println("starting I2S...");
auto config_in = in.defaultConfig(RX_MODE);
config_in.copyFrom(info);
config_in.i2s_format = I2S_STD_FORMAT;
config_in.is_master = true;
config_in.port_no = 0;

config_in.pin_ws = 25; //WS
config_in.pin_bck = 33; //SCK
config_in.pin_data = 32; //SD

// config_in.fixed_mclk = sample_rate * 256
// config_in.pin_mck = 2
in.begin(config_in);

// start I2S out
auto config_out = out.defaultConfig(TX_MODE);
config_out.copyFrom(info);
config_out.i2s_format = I2S_STD_FORMAT;
config_out.is_master = true;
config_out.port_no = 1;

config_out.pin_ws = 14; // LRC
config_out.pin_bck = 15; // BCLK
config_out.pin_data = 18; // DIN
out.begin(config_out);

Serial.println("I2S started...");
}

// Arduino loop - copy sound to out
void loop() {
copier.copy();
}`

I am starting to get really annoyed! Search the issues and discussions first and read the documentation.
The issues with the INMP441 are properly documented!
