Cinema 1200 - Audio or Video Dropouts (AppleTV)

There have been reports of audio and video dropouts happening when using the Netflix app on Apple TV's. This is a known issue with Apple TV, and will occur even if the soundbar is disconnected.

A power cycle of the Apple TV and the affected tvOS version (15.2) should resolve the issue temporarily, and hopefully a future update of the Apple TV will fix this issue permanently.
