random muting on my system

I am having this issue too. Happens every night whilst asleep. Get woken up by the bright green mute LED! Please fix this as soon as possible!

Same here. Multiple One's SL, Arc, Move. They all go into mute multiple times a day. Sometimes all, sometimes only a few.

Seems to be a pretty widespread bug related to a firmware update. Hope this is is given top priority.

I had my system on from 8am until 6pm yesterday and it happened at least 5 times throughout the day and that was while listening to TuneIn & Spotify, both launched via Alexa. I had to reset the volume on all the speakers each time and then later in the evening they all randomly jumped up in volume on their own accord.

Woke up this morning and all but one of my speakers has the green mute button illumintaed. This is not good and needs fixed ASAP...

Been woken up the last two mornings, with the bright green “Mute” glare on both the Ray and Five.

Sonos seem to have really dropped the ball lately with both the ‘App’ and now unstable updates.

Premium product credibility is being eroded away methinks!

Same issue. Not all speakers move to 0 at the same time. Sometimes just part of a group will go to 0 while the rest will not change. Log #************* sent.

Note with regard to Diagnostic confirmation numbers: SONOS staff do not automatically review diagnostics. In the distant past, support was not able to easily find diagnostic submissions and asked that users record the number and reference it during discussions. Users were also encouraged to post the confirmation number here. SONOS is now able to easily fetch diagnostics associated with an account and discourages posting confirmation numbers publicly, citing security concerns.

It’s likely that a moderator will edit the above posts and remove the numbers.

Guess what?
Same issue here. Random muting on two of my three components (one ONE and one BEAM)… but not the third one (a ONE as well)… Several times a day. Does seem to happen only when the app is open. When app is closed and I use ALEXA only to control my music, it has been working OK… That seems to suggest it is indeed this new version of the app!

I have no clue about how to submit a report, let alone finding diagnostic codes...

Same happens to me. All speakers turn their volume down to zero and green light comes on. Happens every night and during the day too. Volume doesn't come back up by itself when I play something, I have to turn the volume back up from zero every time 

It's happening at random times whether or not the speaker is playing but you might only notice it if it goes quiet during playback.

If you have smartthings it keeps a log of every event for connected devices and you can see the volume going to zero at random times a few times a day.

Luckily the routine I use sets volume as well as station so it had been unmuting the speaker until I noticed it for the first time when it happened during playback today.
