audio.loop() doesn't loop

[witivx]

Hello, I'm trying to run the follwing code but it doesn't run properly. Nothing is happening when I'am trying to read .mp3 file, and by passing .wav it is working but only once. I have to unpower and power the board to make it work again. I'm running the code with an ESP32-Wroover-dev from FREENOVE, the MAX98357A amplifier and Adafruit 254 micro SD reader. The code : `#include "Arduino.h" #include "Audio.h" #include "SD.h" #include "FS.h"

// Digital I/O used #define SD_CS 5 #define SPI_MOSI 23 // SD Card #define SPI_MISO 19 #define SPI_SCK 18

#define I2S_DOUT 25 #define I2S_BCLK 27 // I2S #define I2S_LRC 26

Audio audio;

void setup() { pinMode(SD_CS, OUTPUT);
digitalWrite(SD_CS, HIGH); SPI.begin(SPI_SCK, SPI_MISO, SPI_MOSI); Serial.begin(115200); if(!SD.begin(SD_CS)) { Serial.println("Error talking to SD card!"); while(true); // end program } audio.setPinout(I2S_BCLK, I2S_LRC, I2S_DOUT); audio.setVolume(15); audio.connecttoFS(SD,"/ready.wav"); }

void loop() { audio.loop();
}`

You could add some aux functions to get more information, like the below

// optional
// void audio_info(const char *info){
//     Serial.print("info        "); Serial.println(info);
// }
// void audio_id3data(const char *info){  //id3 metadata
//     Serial.print("id3data     ");Serial.println(info);
// }
// void audio_eof_mp3(const char *info){  //end of file
//     Serial.print("eof_mp3     ");Serial.println(info);
// }
// void audio_showstation(const char *info){
//     Serial.print("station     ");Serial.println(info);
// }
// void audio_showstreamtitle(const char *info){
//     Serial.print("streamtitle ");Serial.println(info);
// }
// void audio_bitrate(const char *info){
//     Serial.print("bitrate     ");Serial.println(info);
// }
// void audio_commercial(const char *info){  //duration in sec
//     Serial.print("commercial  ");Serial.println(info);
// }
// void audio_icyurl(const char *info){  //homepage
//     Serial.print("icyurl      ");Serial.println(info);
// }
// void audio_lasthost(const char *info){  //stream URL played
//     Serial.print("lasthost    ");Serial.println(info);
// }

i have the same problem.

I have the following code on the setup function (to debug and to try to get it working):

Serial.println("Setting up audio player...");
audioPlayer.setPinout(AUDIOPLAYER_BCLK, AUDIOPLAYER_LRC, AUDIOPLAYER_DOUT);
audioPlayer.i2s_mclk_pin_select(AUDIOPLAYER_BCLK);
audioPlayer.setVolume(100);

Serial.println("AFTER SETUP ========================");
Serial.println(audioPlayer.isRunning());
Serial.println(audioPlayer.getVolume());
Serial.println(audioPlayer.getBitsPerSample());
Serial.println(audioPlayer.getFileSize());

audioPlayer.connecttoSD("/amaze.mp3", 0);

Serial.println("AFTER CONNECT ========================");
Serial.println(audioPlayer.isRunning());
Serial.println(audioPlayer.getVolume());
Serial.println(audioPlayer.getBitsPerSample());
Serial.println(audioPlayer.getFileSize());

on the void loop i have audioPlayer.loop();

and now i also added the aux functions. On the Serial monitor i get:

Setting up audio player...
AFTER SETUP ========================

info        PSRAM not found, inputBufferSize: 6399 bytes

3980786
info        Closing audio file
info        End of file "amaze.mp3"
eof_mp3     amaze.mp3

i think it is reading the file, because it gets the correct byte size (3980786) and we get 1 on the .isRunning(). But immediately after that it shows Closing audio file.

No idea on what the problem is... If you want to take a look this is on the emilBox github

getFileSize() transfers the value of the file.size() function of the SD card. This only works as long as the file is open. Within an mp3 file there are one or more ID3 headers and sometimes images are embedded. The size of the file is bigger than the size of the audio data block.

@schreibfaul1 Thank you for you answer. Do you have any idea of what the problem is, how i can fix it or debug it any further?

[schreibfaul1]

one possibility would be:

void audio_info(const char *info){
    Serial.print("audio_info: "); Serial.println(info);
    if(strcmp(info, "stream ready") == 0){
        Serial.printf("FileSize is %i bytes\n", audioPlayer.getFileSize());
    }
}

@schreibfaul1 thank you, i will try that tomorrow when get home

[luis-pato]

@schreibfaul1 I have added this function to my code and i get

Unfortunately i have no idea what to make of these results

[luis-pato]

@schreibfaul1 maybe you have an idea?

[luis-pato]

Could the problem be my mp3 file. Maybe some problem with the metadata? Here is the met data of the file i am using: https://www.metadata2go.com/result/7053de8f-2c28-4808-b40e-761d829c89b8

[schreibfaul1]

I can't see that from the data. The ID3 header may be the cause. To convert an audio file to mp3 I recommend using VLC Player or Audacity.

[luis-pato]

ok, thank you, i will try that
