A:Answer Hello Carl,
You will need to enable Dolby Digital+ within your TV for this to work. Navigate to Settings, and then select Sound. Select Expert Settings, and then select Digital Output Audio Format. Next, choose your desired audio format: Dolby Digital+.
If your TV is unable to change to this setting, then you will not be able to play Atmos content from your TV to your soundbar through streaming apps.
