RMTP iOS, audio causes video stutter

I am currently developing a video conference app for Desktop, iOS, and Android.

I'm experiencing a problem that happens only on iOS. My app connects 2 live feeds together with rtmp. Everything works fine on the Desktop or on Android, but on iOS, whenever it recieves any audio from any of the other broadcasting clients, the video immediately pauses... and then resumes once the audio has played.  Without fail, every murmur or whisper I make, immediately the video pauses, the audio plays, and then the video resumes.

I've been working on this app for a while now, since AIR 3.2... and when initially building we did not have this problem. I believe it could be because I updated the project to a more recent version of AIR, be it 3.6, 3.7, 3.8 (sadly, we didnt notice this problem until now)

Has anyone ever expierenced anything like this?

If I mute the microphone from the end that is sending it's audio to IOS, the video plays perfectly no sutter.
