I need help in an issue;
I have develop the code for esp32 to play mp3 file from the sd_mmc using I2S. I believe the esp32 is reading perfectly from the card but not able to play it.
The hardware i am using is ESP32, MAX98357A I2S amplifier module and SD_CARD_MMC.
Here is the code:
`#define MP3_FILENAME "/video/audio.mp3"
static AudioGeneratorMP3 *mp3;
static AudioOutputI2SNoDAC *out; // Use AudioOutputI2SNoDAC for MAX98357A
static AudioFileSourceFS *aFile;
void setup()
{
Serial.begin(115200);
// Init SD card
if (!SD_MMC.begin("/sdcard", true)) // 1 bit mode
{
Serial.println(F("ERROR: SD card mount failed!"));
while (1);
}
out = new AudioOutputI2SNoDAC(); // Output to MAX98357A
out->SetPinout(22, 26, 25); // DOUT on pin GPIO_22, BCLK on pin GPIO_26, LRC on pin GPIO_25
out->SetGain(2);
mp3 = new AudioGeneratorMP3();
// Open the MP3 file
aFile = new AudioFileSourceFS(SD_MMC, MP3_FILENAME);
if (!aFile)
{
Serial.println(F("MP3 file not found!"));
while (1);
}
// Play audio
while (mp3->isRunning())
{
Serial.println(F("MP3 is Running"));
Serial.println(mp3->isRunning());
if (!mp3->loop())
{
Serial.println(F("MP3 Stop"));
mp3->stop();
}
}

aFile->close();
Serial.println(F("MP3 audio end"));
delay(5000);
}`
From the print statement i think in starts playing and stop immediately.
Here is the log:
Any help :)
