Hi ​@MarkDB 

Welcome to the Sonos Community!

Sorry to hear of this audio interruption issue you are having with your Sonos Ray.

I am about 95% confident that you can resolve this issue by simply unplugging your TV from power for at least a full minute, or two.

If that does not help, please try rebooting the Ray too.

I hope this helps.

Thanks, I’ll give that a try. 

Sadly still doing it. Sounds almost like a ticking noise. Tried rebooting tv and soundbar. 

I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. But don’t post the resulting diagnostic number here, they 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.

Hi ​@MarkDB 

Before calling in, please try changing your TV’s digital audio output format from Auto to Passthrough, or vice versa. 

But yes - if that does not help either, I agree that the best move would be to call in.

I hope this helps.
