Well as far as I know, it should work. But what kind of TTS are you speaking of?

TTS library 1.00 in B4A

No. Should work in new versions.

The method documentation: https://developer.android.com/refer...Manager.OnAudioFocusChangeListener, int, int)

Worth trying with GAIN_TRANSIENT_EXCLUSIVE (4 instead of 2): https://developer.android.com/refer...ager.html#AUDIOFOCUS_GAIN_TRANSIENT_EXCLUSIVE
