The Dolby Atmos poster is fixed or appears repeatedly in an LG G4 and Sonos Home theatre

After changing the HDMI, restarting connections and other configuration tips, this problem continues to occur

I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here, their lawyers get sensitive about GDPR.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.
