Inquiry About setFileLoop Function Removal and Potential Re-Addition

[zx12864]

Hi @schreibfaul1,

Thank you for maintaining the excellent ESP32-audioI2S library! I'm working on a project that relies on looping audio files from an SD card, and I noticed that the setFileLoop function seems to be unavailable in the latest version (3.2.0i).

Background

In previous versions (e.g., as mentioned in Issue #542), the setFileLoop(true) function was used to enable seamless looping of audio files. However, when compiling my sketch with version 3.2.0i, I encountered the following error:

error: 'class Audio' has no member named 'setFileLoop'; did you mean 'setFilePos'?

The Wiki previously mentioned setFileLoop for looping audio files, but this information appears outdated or removed.

Questions

1. Has the setFileLoop function been intentionally removed in version 3.2.0i or later? If so, could you share the rationale behind this change?
2. Is there an alternative method in the current version to achieve seamless audio looping from SD card files (e.g., mp3 or wav)?
3. Would you consider re-adding setFileLoop or a similar function in future releases? This feature is critical for my project, which requires continuous looping without noticeable gaps.

Project Details

• Hardware: ESP32-S3 with MAX98357A I2S DAC
• Library Version: ESP32-audioI2S 3.2.0i
• Arduino IDE Version: [Specify your version, e.g., 2.3.2]
• Relevant Code:

  audio.setPinout(I2S_BCLK, I2S_LRC, I2S_DOUT);
  audio.connecttoFS(SD, "/test.mp3");
  // audio.setFileLoop(true); // This line causes the error

• Behavior: I attempted to implement manual looping by checking audio.isRunning() and reconnecting with connecttoFS, but it introduces a noticeable gap between loops.

Any guidance or recommendations would be greatly appreciated. I'm happy to provide more details or test any suggested workarounds. Thank you for your time and support!

Best regards,

The setFileLoop caused some problems with the codecs and has been removed. As an alternative, you can use the audio_eof_mp3 event to wait for the end and restart the file.
