How to Enable Dolby Atmos on Sony TV

 Connect one end of the HDMI cable to the HDMI OUT eARC/ARC port of the soundbar and the other end to the HDMI IN eARC/ARC port on Sony TV.
 After connecting the cables, press the Home button on the remote control.
 Open the Settings menu.
 Scroll down and choose the Display & Sound option.
 Select the Audio Output option.
 Now, scroll down and click the eARC mode.
 In the eARC mode, enable the Auto option.
 Now, the Dolby Digital Plus output option is automatically enabled.
 Check the Speakers option is enabled as Audio System.
 Now, play any video on your Sony TV. You will get the Dolby Atmos sound output on the external speakers.
 On the playback screen, you will get the Dolby Atmos icon.
Sony TV doesn’t have built-in Dolby Atmos support. You have to connect a Dolby Atmos-supported speaker to your TV. This means that your TV is capable of decoding Dolby Atmos output and passing it through the external sound systems. This is known as Dolby Atmos passthrough.
