interruptionEventStream doesn't emit a new item when TalkBack is on (Android) about audio_session HOT 3 CLOSED

That doesn't surprise me, Android considers TTS and music as different kinds of audio streams which is also why I provide that hack in audio_service to force the media buttons to show by playing a little bit of "real" audio (or what Android considers real audio. TTS doesn't count, since it's on it's own special audio stream.) Anyway, that's not exactly the same issue here, TalkBack could have been programmed to request audio focus if they wanted it to, but I guess the fact that they didn't is consistent with their overall approach to treat TTS output differently from normal audio output.

Can you point to any other audio apps that correctly handle the interruption?

After further investigation I can say it's not a bug of this plugin 🙂
I've checked Spotify, Youtube and Google Podcasts apps with ducking off and all these apps continue playback while TalkBack is in use. I'm using text to speech plugin along with audio_service and audio_session. Turns out TalkBack with ducking off stops TTS engine's playback directly but doesn't do anything with media players and their audio focus\session. TTS plugin I'm using receives a stop\interruption event but audio service and audio session don't and this is not an issue of this plugin but rather how things work on Android with that setting off.
