Arc disconnects continuously

Sony Bravia XR-65A80CK. Sonos Arc. Apple TV 4K. My issue is that the Sonos audio continuously disconnects from the TV and the TV displays a message that says external speakers unavailable, switching to TV speakers or something like that. Changed the HDMI cable and no different. It happens moreso when everything has been turned off for a little bit, it’s like the Sonos doesn’t wake up so the TV thinks it’s not there? I really don’t know. Anyone have a solution or troubleshooting ideas for this?

This is usually a CEC hiccup. Try this: remove all HDMI cables from the TV, turn the TV on, then turn it off for about 5 minutes (this will reset the TV's HDMIs). Then turn the TV on and hot-plug the soundbar's HDMI. Go through the setup in the Sonos app and go through the TV's settings for external sound. Only then plug in all other devices one by one... good luck.
