Youtube_player_flutter: No audio - Requires MODIFY_AUDIO_SETTINGS and RECORD_AUDIO

[BethshanDeveloper]

Describe the bug
No audio for YouTube video. It looks like the key line in the console output is "Requires MODIFY_AUDIO_SETTINGS and RECORD_AUDIO. No audio device will be available for recording" (full output below). The video plays fine, it's just the sound that is an issue.

To Reproduce
Code:

class TestYoutube extends StatelessWidget {
 final YoutubePlayerController _controller = YoutubePlayerController(
    initialVideoId: '#Secret',
    flags: YoutubePlayerFlags(
        autoPlay: true,
        mute: true,
      ),
  );

  @override
  Widget build(BuildContext context) {
    return YoutubePlayer(
        controller: _controller,
        showVideoProgressIndicator: true,
        progressIndicatorColor: Colors.amber,
        progressColors: ProgressBarColors(
            playedColor: Colors.amber,
            handleColor: Colors.amberAccent,
        ),
    );
  }
}

Expected behavior
I expect the video to play with sound.

Technical Details:

• Device: Samsung S9
• OS: Android 10

Additional context
I've found https://stackoverflow.com/questions/38917751/webview-webrtc-not-working which suggests adding some permissions to the Android side of things. I tried this, but it didn't help with the bug (though it did remove the warning from the console). Also the README for this package says "No configuration required - the plugin should work out of the box." for Android configuration.

The full console log is:

Try using the following:

      ),

Ah yes that's it, what a silly mistake! Thanks 😄
