If your Sonos Beam (Gen 2) experiences intermittent sound interruptions and displays the Dolby Atmos indicator on your TV screen, there are a few troubleshooting steps you can try to resolve the issue: Troubleshooting Steps Check HDMI Connection: Cable Quality: Ensure you’re using a high-speed HDMI cable that supports Dolby Atmos and is in good condition. Faulty cables can cause interruptions. HDMI Ports: Make sure the HDMI cable is securely connected to both the Sonos Beam (Gen 2) and the TV's HDMI ARC or eARC port. Update Firmware: Sonos App: Ensure that your Sonos Beam (Gen 2) is running the latest firmware. Updates can fix bugs and improve performance. Open the Sonos app and check for any available updates. Check TV Settings: Audio Format: Go to your TV’s audio settings and ensure that the audio output is set to Dolby Atmos or bitstream rather than PCM. HDMI CEC: Enable HDMI CEC (Consumer Electronics Control) on your TV, which can help manage the soundbar’s communication with the TV. Roku Settings: Audio Settings: Ensure that the Roku’s audio settings are set to pass-through Dolby Atmos. Go to Roku’s settings and set the audio mode to “Auto” or “Dolby Digital Plus” if available. Sonos Beam Settings: Trueplay Tuning: If you haven't already, run Trueplay tuning through the Sonos app to optimize the Beam’s sound performance for your room. Check for Interference: Other Devices: Ensure there are no other devices or apps causing interference with the Sonos Beam’s performance. Restart Devices: Reboot: Restart your Sonos Beam, TV, and Roku to reset their connections and clear temporary glitches. Reconfigure HDMI ARC/eARC: HDMI Settings: Double-check the TV’s HDMI ARC or eARC settings. Sometimes reconfiguring or resetting these settings can resolve audio issues. Test with Other Content: Different Source: Try playing different content to see if the issue persists across various sources or if it’s isolated to specific content or apps. If these steps don’t resolve the issue, consider reaching out to Sonos customer support for further assistance
