Im having issues on my project and is driving me crazy.
I have a function that gets called when a coin is inserted in my smart piggy bank that plays a sound effect depending on the coin.

void playCoinSound(int coin)
{
  char path[MAX_FILE_PATH_LENGTH];
  char files[MAX_FILES][MAX_FILE_PATH_LENGTH];
  int count = 0;

  sprintf(path, "%s/%d", COIN_SOUND_FOLDER_PATH, coin);
  if (loadFiles(path, files, count))
    return;

  for (int i = 0; i < count; i++)
    Serial.printf("%d. %s\n", i, files[i]);

  player.setPath(files[rand() % count]);
  player.play();
}

After calling this function several times, the board stops playing any sound. I.m sure the function gets called correctly so my guess is that i'm not managing the state of the board in a proper way by just calling the two instructions

player.setPath(files[rand() % count]);
player.play();

I've tried calling adding the .end() function before changing audio file form the player, but the issue still remains.

player.end();
player.setPath(files[rand() % count]);
player.play();

This is the log I usually get when everything is working.

When it stops working the logs become way smaller missing all the i2c part, however, no sound is played.

I am sorry, but I am currently not able to do any investigation and I have never been using the AudioPlayer this way.
Maybe you can discover what the issue is If you set the log level to debug but if the copy lines are ending you are probabliy at the end of the file, so there is nothing to copy anymore. I would also expect that if you call end, you will need to call begin again!

My suggestion would be to consider to use a simpler design and just copy your file to an EncodedAudioStream....

I could't get this example working on my board. Parameters are not correct. Any suggestion?

Just replace the audiokitstream with your desired output device or use the stream examples directory to select the example

Perfect, the suggestion worked, now i'm not expecting the issue

As I said, the issue is fixed, however I'm getting a little cracking effect before playing a sound.
Do I have to clear some buffers in the EncodedAudioStream or StreamCopy object?
The first played sound is clean, the issue start on the second and so on
