"I had this issue as well. I only had sound on some Netflix movies with my Apple TV. What I did was go into my audio and video settings on the Apple TV and turned off the dolby digital, turned on sound check. Dont know if that last part made a difference but I saw that step on a different question for sound issues. But after I did those steps it started working. Hope this helps."

No sound in streaming Netflix with Apple TV?

Thought I would pass this along. I had this issue with some of the newer movies like The Fighter and Skyline.
