Using url to analog example leaves speaker "bugged" repeating last fragment

[FGAC1226]

I am using the "Streaming Radio Player" example (https://github.com/pschatzmann/arduino-audio-tools/tree/main/examples/examples-stream/streams-url_mp3-analog) to play a text-to-speech mp3 file from a server, and it's all working almost as expected, except that after the mp3 is finished, the speaker keeps playing the last half-second or so over and over on repeat.
The expected behavior is for the speaker to just go silent.

Additionally, in the example, "copier.copy();" is just left on the "void loop". Would a

//Some Code
while(copier.copy()){
copier.copy();
}
//More Code

make the code continue after the file stops playing? Or is there another recommended way?
Thank you very much

I am not sure where this would come from. In any case I could never reproduce this myself, so it could be related to your hardware.
There are plenty of options that you can try:

1. Use a wav file instead of a mp3
2. instead of copy in the loop just do a copyAll() in the setup
3. when the copy is done (if copier.copy()==0) you could
   3.1) close the output: analog.end()
   3.2) just continue to write silence: output.writeSilence(1024)

Many thanks for your answer, I tried keeping it as a mp3 file and using analog.end(), which works "well" (now instead of repeating it forever, it's just a couple of times).
I would use it as a wav, but for some reason, when it's a wav file no audio plays.
I think this might be related to the server-side though, since when manually visiting the web it seems that if the file plays natively in the browser, the arduino plays it without issue, but when it instead auto-downloads, no sound comes from the arduino.

In the code I just changed "audio/mp3" to "audio/wav".

Thabk you for your help, and for providing and maintaining such an amazing library.

I added the auto_clear attribute to the config. It might help to set config.auto_clear = true;
I was running into the same issue in the I2SStream when this was not set to true...
