7. Troubleshooting

This section addresses common issues you might encounter with your Sonos Arc Ultra.

7.1 General Connectivity Issues

  • Soundbar not pairing with TV: If the soundbar occasionally loses connection or fails to pair with your TV, try turning off both the TV and the soundbar, then power them back on. Ensure your TV's HDMI eARC setting is correctly configured.
  • Soundbar loses contact after Trueplay tuning: If this occurs, power cycle the soundbar by unplugging it for a few seconds and then plugging it back in.
  • Sonos App issues: Ensure your Sonos app is updated to the latest version. Restarting the app or your mobile device can resolve minor glitches.

7.2 Audio Format Limitations

  • DTS-X Decoding: The Sonos Arc Ultra does not decode DTS-X audio format. Ensure your source content or TV is configured to output compatible audio formats like Dolby Atmos, Dolby Digital, or PCM.

7.3 Regional Feature Availability

  • Voice Assistant: Sonos Voice Control, Amazon Alexa, and Google Assistant features may not be available in all regions, including India. This is a regional limitation and not a product malfunction.

7.4 Physical Connectivity

  • Single HDMI Port: The Arc Ultra features only one HDMI eARC port. Direct connection of other HDMI-enabled devices to the soundbar is not supported. All devices should connect to your TV, and the TV will then send audio to the soundbar via eARC.
  • Optical Connection: An optical audio connection is not natively available. An adapter cable from Sonos is required if an optical connection is necessary for your setup.
