I'll be asking some questions to further assist you on this and will give you some of the suggested troubleshooting steps that you can follow.

1. When did the issue start happening?
2. Any changes that happened on the network/outage/power surge?
3. On which speaker are you experiencing the issue? During group or individual playback?
4. Do you experience the issue during the TV playback, music playback, or local music library?
5. Is the speaker usually wireless or wired?
6. Have you tried rebooting your network devices and all your Sonos speakers?

Please try to play music to test the playback for a few minutes then run a diagnostic. Just include the confirmation number in your response so that we can look up the information.

There has been no changes to our system no power outage I have rebooted everything this is in the room with my sound bar, subwoofer and two play ones. the sound bar is wired directly into the Internet it started about three weeks ago and it does not happen during TV only when streaming music it just goes silence for 5 to 10 seconds and then randomly starts playing again and happens every 30-60 seconds

Hi @Jlew, thank you for your response and for providing the diagnostic report. Let me help you out with this. 

Based on the diagnostic, your Sonos system detected out of sync with your network, and your Sonos speakers have been up for 60 days. Let me suggest the next troubleshooting steps, 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. 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.
3. If you have access to your router settings, below are the settings that need to be verified. You can contact your Interner Service Provider or router manufacturer for assistance.
   • The auto channel must be set to Off
   • Choose the best non-overlapping channel (1,6,11)
   • Set channel bandwidth to 20MHz
   • Both 2.4GHz and 5GHz should be enabled
   • UPnP should be enabled
   • 802.11 bands should be set to b/g/n
   • Airtime Fairness should be disabled (if applicable)

If you're still having the same issue, please contact our Sonos Customer Care support with your full network setup including the make and model for each device.
