Hi there, I am having trouble with a new ATV 4. Occasionally sound is out of sync. I have noticed this with iTunes purchases and Netflix. A restart of the ATV 4 solves the problem. Is anyone else experiencing this? I has occasional similar problems with the ATV 3 on Netflix. With the ATV 4 I am using a brand new Apple HDMI cable. I thought it might be my TV, but then why would a restart of the box temporarily fix the problem? I am just using the TV's built in speakers. Any help or advice is greatly appreciated!
