Im playing an audiofile from remote. On Android this implementation is working perfectly fine, but on iOS the audio is not playing.

Current bug behaviour

On iOS the audio is not played, and in the logs i cannot see an error.

Expected behaviour

I Expect iOS to be behaving the same as Android

Steps to reproduce

I followed all the steps outlined online and in the pub.dev documentation.
The audio is played by this command:

• AudioPlayer chatAudioPlayer = AudioPlayer();
• await chatAudioPlayer.play(UrlSource(widget.audioUrl));

The only output I'm seeing in the logs is "iOS => call play, playerId e9117dde-db8b-4623-afaa-63915f20326b"

Remote audio file; https://trackler-track-uploads.s3.eu-central-1.amazonaws.com/2147/637d32d06f6b7.mp3

I tried playing this file https://www.learningcontainer.com/wp-content/uploads/2020/02/Kalimba.mp3 and this is working.
Does anyone notice a difference between the two urls?

I've tried that approach but it's not working either.
Looks like something with the audio format, but not sure what.
