I have a pretty specific issue. I have a projector (Epson 4K Projector EH-TW7000) hooked up to my apple tv (4k) with hdmi. I’m considering the purchase of a sonos sound bar, and to try it out I figured I’d hook up my sonos roam. It pairs seamlessly (although it will not allow me to set it up as a default audio device) and while watching something I’m quite happy with it.

But, each time new media is started (e.g. a youtube video, but even each seperate ad), or when I exit media to the menu, the image goes black for about 15 seconds (audio continues).

This problem does not occur when I use a different screen with the same setup, of when I play the audio through my projector only.

I hope this sounds familiar to someone!
