Yeah, I know it's different from other apps, and it use different audio stream, and can't install another radio app without root.

Internet radio app, you mean like online radio? It's not a option, no internet, only FM.
I did try with DAB radio, and its all OK, but because its a third-party app and usb DAB so it's use different audio stream.

Only this built in radio app is blocking tts.
