Play 1 speakers volume fades in and out

But my question is why this voice only fades on Play 1's and not on soundbar? When both of them are connected to same TV and same internet. Not sure, if there is some other problem with just Play 1's.

The PLAYBAR is wired into your TV and will play audio even if it is not connected to your network. The PLAY:1s communicate wirelessly with the PLAYBAR to play the audio. It may not be the solution but it's worth clearing up the connection errors then we can move on to more troubleshooting.

I am having the same problem with sound fading in and out from Play-1s. I sent a diagnostic report from the SONOS app along with the confirmation number. I have not heard back regarding how to fix the problem. If the play -1 speakers are losing connection with the wireless modem, how do I fix that?

If you don't post the diagnostic number here, or call in and give it to them on the phone, they likely won't look at it. I imagine they get thousands of submissions daily, and probably don't know which ones to look at and which ones to ignore unless you communicate to them.

Do it again, within 10 minutes of the fading issue, and then come back here and post the number. They're much more likely to respond. Or call them, from all reports, their phone staff is great, too.

Thank you for the advice. I actually called tech support today and my problem was resolved remotely.

Outstanding!

Would you be willing to share the resolution, for those who may find this thread at a later date with a similar issue?

After contacting SONOS troubleshooting I found out I didn't have Real surround sound. The technician remotely changed the configurations and also changed the modem channel from 7 to 1. Everything works well now.

I am having a similar issue with my Play 1. However, my Play 1 is stand alone and I only use it to stream music from Spotify. When the volume is turned up high, the level will drop periodically and then go back to normal in a couple seconds. Diagnostic report number 8361327.

Are you sure the speakers are not ducking because someone in house is talking to Alexa. I have my playbar system disabled in the alexa skill for this reason.
