When ever I stream any video via iTunes or Netflix I don't get any audio. However, I do get audio when cycling through the menues and listening to music. I do however get audio if I stream video from my iPhone.
Try Settings for audio and video and set Dolby Digital to Off or Auto.
I've tried streaming the movie with "Dolby Digital" Set to "Auto" and "On" but still no sound. "Audio Output" is set to "Auto".
