I hoped that moving from an ESP8266 to an ESP32 (I tried both ESP32-C3 and now a WROOM) would solve all my problems, but ...

I reduced my platform.io program to:

#include <Adafruit_GFX.h>
#include <Adafruit_SSD1306.h>
#include <Arduino.h>
#include <EEPROM.h>
#include <I2S.h>
#include <LittleFS.h>
#include <SPI.h>
#include <WiFi.h>
#include <Wire.h>

#include "AudioFileSourceBuffer.h"
#include "AudioFileSourceICYStream.h"
#include "AudioFileSourceLittleFS.h"
#include "AudioGeneratorMP3.h"

// Enter your WiFi setup here:

const char password[] = WIFI_PASSWORD;

Basically just trying to play a short MP3 file of a phone ringing from LittleFS, which the code in setup() also shows being present when starting this on my ESP32 WROOM device. I'm not even at the point yet where the audio-quality interests me. Just getting the MP3 decoding to work without errors would be step 1 ...

Unfortunately even that doesn't work (whereas I have similar - but not exactly the same - code on ESP8266 which does work). Instead I get following output from the status callback for every playback of the file:

MP3 playback stopped
UNINSTALL I2S

I checked the MP3 file and it's fine (here it is in a ZIP file: phone.zip). My ultimate goal is playing an MP3 Internet stream to an I2S DAC, but as that gave similar issues, I simplified the code to this LittleFS playback.

I did also try with an older (0.9.7) version and had the same issues there.
I did also try using an AudioOutputNull instead of AudioOutputI2S and AudioOutputI2SNoDAC, but to no avail.

So, I'm out of ideas ...
Any help or at least confirmation that this is a known problem would be very welcome!
