Sound loss in iOS

[whiskey236]

First, thank you for providing ezSTT ANE and ezSpeech ANE both of which I bought recently.

The issue I am having is on iOS only (12.4.1), after calling the voice recognition, TTS works but any sound from my app no longer works. I had to exit to home screen then switch back to my app to make it work again. All previous sound are now played back to back as if it was queued in memory. No problem in Android mobile, the sound is maintain.
