New update to Apple TV, Now my sound bar doesn’t turn on

Hi SteveInMD,

Thank you for using the Apple Support Communities! For this issue, we would recommend the article below that can help:

If you can't control your Apple TV with your home theater or universal remote

1. Add your Apple TV to the Home app and make sure that you assign it to a room.

2. Add the remote to the Home app on your iPhone or iPad and make sure that you assign it to a room.

After you add the remote to the Home app, you can use it to control any Apple TV that you have in your home.

Or:

If your Siri Remote or Apple TV Remote isn't working

1. Stay within 20 feet (about 6 meters) of your Apple TV and move anything that blocks the path between your remote and the front of your Apple TV, television, receiver, and sound bar.

2. Charge your remote for 30 minutes using a USB-C to USB or Lightning to USB cable and a USB wall charger.

3. Unplug your Apple TV from the wall power outlet. Wait at least six seconds, then plug it back in.

If the volume buttons on your Apple TV remote stop working, learn what to do.

If the issue remains, we recommend that you reach out to Apple Support directly to take a further look. Please reach out here:

Hope this helps!

Have a great day.
