Disconnect the mobile device connection (e.g., turn off Bluetooth on mobile or switch Soundbar source) and the TV sound should resume output from the Soundbar.

To enable AirPlay2, you must first register the Soundbar using the Samsung SmartThings app and agree to its terms.

AirPlay2 will not work if you delete the Soundbar from the Samsung SmartThings app.

Ensure the Soundbar and your Apple device (iOS 13.4 or later) are connected to the same Wi-Fi network.
