Hi @mattfort.
Thanks for your response and please accept my sincerest apologies for the delayed response time.
Upon checking the diagnostic report, the system detected transport and sync errors resulting in audio dropout and playback failure, possibly Sonos is not getting enough bandwidth or experiencing poor wireless conditions which are often caused by wireless interference around Sonos products. If all the recommended steps to reduce wireless interference were followed and it doesn’t help, then knowing how and through what Sonos is connecting is the great foundation to troubleshooting this successfully.
Due to the nature of this issue, it would be best to have our phone team take a look. Please call us up to work with a technician live, they'll start by checking your system health and go from there. They have resources available for advanced troubleshooting, and the tools our agents can use would be very useful in this case, there can be an advantage if they need to remote into the controller to see what's going on.
If you have any questions or concerns, feel free to let us know.
