Hi Phil,

I think I understand now. The Mezzmo Android app's video player is decoding the incoming audio as PCM for playback, which may explain why you are getting only 2 channel audio. We have planned to improve this in an upcoming release.

A solution for you now is to stop using Mezzmo Android's video player and choose your own video player (MX Player, VLC, etc.). Go to Settings in Mezzmo Android and turn off the "Use Internal Video Player" checkbox. Now Mezzmo Android will use whatever video player app you have installed on your Android device.
