Hi Simon B

Thanks for your response, since my first message I have not experienced the issue, however I have not been using my multi fuel burner since the fault, which leads me to think it was a heat issue.

Is there a recommended distance from a heat source it should be mounted?

I don't know if this will help but here is the report number from 24-12-2020.

Ref# 24558329

Hi there, @Johnny50, thanks for the update and for sending a diagnostic report of your Sonos system, upon checking, it shows an Amp fault on the Sonos Arc. An amp fault is a specific type of hardware fault that clamps the max volume to 15 to protect the internal circuitry. Which is odd for a Sonos Arc. there’s also Wi-Fi interference detected on your system. You may check this article about Wi-Fi interference. But for the other issue. We’ll take it further. I'll ask you to kindly contact our phone support team for further assistance and more in-depth troubleshooting steps.  

Keep us posted on how it goes and we're here to answer any further questions you have.

Thanks for the update Simon B.

Am I right in saying that there is no heat issue detected then, because in my opinion it doesn't get that hot in the position it is mounted although I haven't actually taken a temperature reading.

I will update you once I've spoken to the support team.

Thanks again for your help.

Johnny.

Hi Simon 

I spoke with Angela K earlier today regarding the issue with my sonos arc, for now she guide me through a hard reset as the issue has not been evident for the last few days.

If the problem reappears she asked me to submit a report and the next step would probably be a replacement unit.

Fingers crossed and thanks for all your help.
