Short Answer

Atmos needs an eARC or compatible ARC connection, an Atmos source and the TV set to pass-through. Check the HDMI port and the TV audio format.

Dolby Atmos is carried inside Dolby Digital Plus or TrueHD. The TV must pass the signal through to the bar and the app must offer Atmos.

After you make the change, play the Surround Sound Test again to confirm the result. If the problem is still there, add your device, browser and what you tried in the replies so the team can narrow it down.

Step By Step Fix
  1. Plug into the HDMI port marked eARC
  2. Set the TV audio output to Pass-through or Auto
  3. Open a title with Atmos and check the info panel
  4. Use the manufacturer cable that supports eARC

    Pass-through was the missing option on my LG. I tested it on my own setup and it held up for weeks.

    My Netflix needed the premium plan for Atmos. I checked it again with the Surround Sound Test afterwards to be sure.
