One of our sonos play1s occasionally fades in and out of music when paired with the other sonos play1 and the sound bar. So when they are all playing together this happens.

Please advise
Does it really fade, or does it just cut out? I'm trying to understand how a digital signal can fade.



In any case, I'd recommend that the next time it happens, you should submit a system diagnostic within 10 minutes, and either post the number here, or contact Sonos to discuss it. There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.



In most cases of sound cutting out, it's a case of wifi interference, might be worth reading that information.
Hi thanks for this. I can confirm it’s definitely a fade, much like turning the volume down then up. The diagnostic number is 511693517. When playing off the Spotify app on the TV there are no issues with the play bar, only the speakers.

I wonder if this is 'ducking' after the Sonos One has triggered Alexa? What Alexa Groups have you set-up?
No Alexa groups, I don’t have one!

Sorry, I read Sonos One and not Play:1 - my mistake.
Shoot, it's where my mind was going too, it's the only way I know of "fading" a Sonos signal. Let's hope that Sonos can look at that diagnostic tomorrow.
