1. if I hook an AppleTV directly to a tv will AirPods work with the AppleTV regardless if which app is being used on the AppleTV? 2. Is there a way to get the AirPods to work with other devices connected to a tv like a Blu-ray player? 3. Can AirPods work if everything is run through a stereo receiver? Ex; the AppleTV is connected via hdmi to the receiver and not the tv. Thanks.
