M5Stack/Arduino: mp3 player works with Arduino but distorted noise on Platformio

[lidense]

Hi I have a sketch to read mp3 files from my SD card. It works when I compile with the Arduino IDE but although it compiles I can only hear strange distorted noises when I compille with Platformio (with arduino framework, M5 core library and ESP8266AUDIO (VERSION esp32_201 AND 202 compatibility, I did not use the Platformio version of ESP8266Audio which does not compile but rather VERSION esp32_201 AND_202 compatibility. Please advise (cpp file attached) Regards plat1.pdf s

I am experiencing the distorted sound with a fairly simple implementation in the Arduino IDE:

file = new AudioFileSourceSD("/OdeToJoy.mp3");
id3 = new AudioFileSourceID3(file);
out = new AudioOutputI2S(0, 1);
out->SetOutputModeMono(true);
//out->SetGain(0.02);
mp3 = new AudioGeneratorMP3();
mp3->begin(id3 , out);

Tried playing with the gain, thinking the audio was clipping. Also tried using output_mode 2 on the AudioOutputI2S, to no avail. How'd you get it working in Arduino IDE?

Running Arduino IDE 1.18.9, latest version of ESP8266AUDIO, and M5Stack lib 0.4.0

Tried making the project in PlatformIO, with the following configuration file:

[env:m5stack-core-esp32]
platform = espressif32@3.3.2
board = m5stack-core-esp32
framework = arduino
lib_deps = 
    earlephilhower/ESP8266Audio@1.9.6
    m5stack/M5Stack@0.4.0
    gianbacchio/ESP8266Spiram@^1.0

Tried different combinations of m5stack and ESP8266 audio releases... no joy.

I got it working with platformio using the following platformio.ini configuration for my M5 Stack Core 2 (M5Unified is a sort of common library for different devices, some slight changes to the code might be necessary.)

[env:m5stack-core2] platform = espressif32@3.3.2 board = m5stack-core2 framework = arduino lib_deps = m5stack/M5Unified@^0.0.7

So you don't include earlephilhower/ESP8266Audio as a lib_dep specifically? Is it contained in m5stack/M5Unified?

Might also be that you're using a Core2. I'm using the Core.

Yes I did include it but manually manually not via Platformio
