test code for VS1053 on ESP32

[Strider222]

I borrowed a test program for VS1003 on arduino from

andykarpov/VS1003/blob/master/examples/vs1003_hello/vs1003_hello.ino

I think I have modified it correctly but the VS1053 still outputs nothing.

There is a printf in the code that I don’t understand it’s function.
Have I broken the code or do I have bad hardware?

/*
  vs1053_hello
   
  A simple MP3 flow player to test if board and library are working together.
  The following sketch should say "Hello" every 0.5s :)

void loop() {
    // play hellomp3 flow each 0.5s ;)
    player.playChunk(HelloMP3, sizeof(HelloMP3));
    delay(500);
}
