Went to the Cineplex to watch The Diplomat, I asked my gf for her android htc amaze phone to play a game since I was pretty bored out of my mind, I decided to take a 10 second video of the screen to see how the quality of the video might turn out in the dark. Well I got home and theirs completely no audio coming out of the video, and its not as if I had mute on either.

I suppose this might be Cinivia? Or some type of protection on the room? I tried recording with my nokia phone and the audio didnt get muted. So i ask if this is a certain device that gets prevented from getting recorded or what?
