Hi there @Sid-Hartha.

Thanks for reaching out, we’d be glad to help.

To better understand, kindly replicate the issue, then submit a diagnostic report through the Sonos app shortly when it happens, and reply with the confirmation number. I'd start by reviewing your system and go from there, it will help in identifying what's possibly causing the issue.

Looking forward to hearing from you soon.

Sorry for the late reply. It started working again. But has now started playing up again. 
 

I just submitted a diagnostic report. Number 630269484. 
 

Let me know your thoughts. Thanks. 

Hi @Sid-Hartha.

Thanks for your response.

Upon checking the diagnostic report, it shows a sync error that indicates audio dropouts and symptoms indicative of interference has been detected on one or more Sonos components running on the Wifi. 

Commonly, this issue can come as a result of wireless interference, this article will help you reduce wireless interference around your Sonos products. 

Wait for about 3 minutes, then submit a new diagnostic report and reply with the confirmation so I can check if there will be changes.

Let us know how that goes.
