Hi @Ernievm, thank you for your response and for submitting the diagnostic reports. Let me help you and figure out what's happening.

Based on the diagnostic, there's interference in your network that may be caused by wireless congestion, an audio dropout was detected in your due to sync error and the audio feed is too slow causing the playback to stop. These network-related issues that may be causing the issue.

Let me suggest the next troubleshooting steps is to perform a sequential reboot of your network devices, all your Sonos products, and force close mobile controllers to refresh the connection.

1. A sequential reboot means that we need to do this in order.
   • Unplug your network devices (modem, router, any wireless access points on the network) from the power and wait for 60 full seconds before you plug it back in.
   • Once the router is back online, unplug all your Sonos devices from the power. Please wait 15 seconds before you plug back them back in.
   • Force close the Sonos app from your iOS or Android device.
   • When the status light on your Sonos speakers are solid white, get back on the Sonos app and check if you're connected.
2. Ungroup your Sonos speakers
   • Start playback on each speaker to check if the music will stop or skip.
   • Observe your Sonos performance.
3. Change SonosNet channel
   • Changing the wireless channel is a troubleshooting step in reducing wireless interference.
   • Settings tab, select System > Network > SonosNet Channel > Change the wireless channel to 11
   • Observe your Sonos performance.

Let us know how you get on with the advice above and include the confirmation number of the diagnostic report in your response for us to check.
