Greetings, Breadstand!

Thanks for reaching out to the Apple Support Communities! It sounds like you're having an issue maintaining the connection to your sound bar through Bluetooth from the Apple TV. Check out this article to Use Bluetooth accessories with your Apple TV. Specifically:

"Get help

If a Bluetooth accessory won’t connect to your Apple TV 4K or Apple TV HD or loses connectivity during use, follow these steps. After each step, see if you still need help:

1. Make sure that you're in range of your Apple TV and there isn't interference in the area.
2. Check that your accessory is fully charged and powered on.
3. Make sure that the software on your Bluetooth accessory and your Apple TV is up to date. For example, if you have Beats wireless headphones, check for firmware updates.
4. Move your Apple TV to a different location near your television.
5. Look for your accessory in Settings > Remotes and Devices > Bluetooth. If you see it but you can’t connect to it, use the steps above to unpair your accessory. Then try to pair it again.
6. If you need more help connecting or using a Bluetooth accessory with your Apple TV, contact the manufacturer of the accessory."

Let us know the results and have a great day!

They screwed up the update. And AirPlay and Bluetooth no longer stay connected, you have to connect every time your turn it on.

Apple thinks that’s the way it should work. Leave some feedback on the Apple site.
