[BUG]: PlatformException thrown when trying playing local audio file.

See original GitHub issue

Severity

Result is not what expected

Platforms you faced the error

Real iOS 14.5.1 device

Describe the bug

I need to download a remote audio file for editing. I’m using ffmpeg to cut and modify this audio and then I’m using FlutterSound to play the results.

The problme is that a PlatformException exception is thrown when I try to play the local .mp3 file that I downloaded. This exception only happens on a real device and not the emulator.

I was thinking that it could’ve been that I have two active players in the application but after changing to code to use only one the problem is still present. Remote audio files play just fine, the problem only appears when trying to play the file that I download. Once the problem appears the player fails to play remote or local files.

I’m using the following lines to play my audio files:

Future play(String filePath) {
  player.setSubscriptionDuration(_subscriptionHandler);
  return player.startPlayer(fromURI: filePath);
}

To Reproduce Steps to reproduce the behavior:

please allow give me a little bit of time to create a sample project that can reproduce this error.
