Whenever I'm watching a video or TV program though channels and I use the TV button to switch the audio over to my AirPods I seem to lose the audio entirely or only get halt the audio.
Easy fixed by halting the play back and restarted but its a pretty consistent probable so I thought it was worth mentioning..
I'm using a 1st gen Apple TV 4K, and the latest stable channels server running on a Raspberry PI 4 over 1GB wired network.
