#311 Solved it for me (iPhone SE)

Is 3.8.5 not even a valid version then? We always have to downgrade?

Thanks for the suggestion. Unfortunately, the issue still persists.

To be clear, I can't get any sound to play in Google Chrome either. I'm not deploying to Chrome, so I don't mind that. The solution might very well not be iOS-specific though.

@12yanogden Did you find a work around for the iOS simulator issue?

Nope. When I revisit my project, I'm probably going to choose another tts package. This one is simply broken, even for the most basic use case.

@rennylangat I apologize as I have been extremely busy, but will look into some of these issues in the next couple of days. Is this only occurring in your simulator or on an actual device?

[rennylangat]

@dlutton It happens on both. On a physical device I get this Unable to list voice folder error message upon running. Could be an issue with AV Speech Synthesizer?

Adding this after initialisation fixed it for me:

let flutterTts = FlutterTts(); await flutterTts.setSharedInstance(true); await flutterTts.setIosAudioCategory(IosTextToSpeechAudioCategory.playback, [ IosTextToSpeechAudioCategoryOptions.allowBluetooth, IosTextToSpeechAudioCategoryOptions.allowBluetoothA2DP, IosTextToSpeechAudioCategoryOptions.mixWithOthers, IosTextToSpeechAudioCategoryOptions.defaultToSpeaker ], IosTextToSpeechAudioMode.defaultMode );

I also encountered a situation where there was no sound, but in my case it was because I set it to silent mode (Silent switch). I used IosTextToSpeechAudioCategory.playback to be able to play sound even in silent mode.
