Microphone ANE cuts Ios audio (netstream or timeline)

I am using an ANE ezSTT (easy speach to text )  by Fabrice Montifort .  It works great on Android.  But on iOS the ane is not working when using a combination of microphone and audio (either netstreaming audio or small audio on the timeline. Curiously it cuts out audio from my streaming video too.)    For example - it will capture microphone sound - and succesfully render the speach-to-text.  But if I then play an audio - no sound.

Does anyone have a clue to re-initiate the audio after I use the ANE to capture microphone sound ?

the ane sets some pretty straightforward commands

import com.fabricemontfort.air.ezSTT;

import com.fabricemontfort.air.ezstt.STTEvent;

import com.fabricemontfort.air.ezstt.languages;

var stt: ezSTT = ezSTT.instance;

function . .. .

stt.start();

stt.addEventListener(STTEvent.FINAL, onFinal);

stt.addEventListener(STTEvent.ERROR, onFinal);
