Sonos Amp blasting music at 4 AM outside

What was something that happened a couple times in the past is now more serious. I live in a quiet neighborhood. There have been a few times in the past where I noticed that music was on outside and I just simply turned it off. I have a Sonos Amp connected to 6 outdoor Sonance speakers and a large sub as our ‘Backyard Sonos’. The volume was low, and it’s possible it was playing for days. I just hadn’t been in the backyard to hear it.

There have also been a couple times when we noticed super loud beeping coming from the outside Sonos system. We noticed the backyard zone volume was set to 100%, but no music was set on that zone. I had to unplug it to reset it, because if I just moved the volume down it would just go back up. Again, this happened twice around 11 PM. It’s just my wife and I - we were in bed. There are no alarms set and no integration with stuff like Alexa or Google Home.

It’s now almost 4:30 AM while I am writing this. I just woke up to my backyard Sonos blasting ‘Milky Chance’ at 98% volume. I’m not clear how the police haven’t been called to my house yet….or my neighbors banging on my door. 

From a quick Google search, I can see where Sonos randomly playing music is a common thing. Unfortunately, I’m not seeing any solutions. I don’t have any voice assistants. Everyone is asleep. Even if it started playing on its own, why is the volume at 95%? If I want to listen to it ‘loud’, I would maybe have it at 70%. It wasn’t playing from an AirPlay source, it was playing Pandora Radio...which was likely that last thing I was listening to.

As I’m writing this, I reviewed some camera footage from my backyard. The music started at exactly 2:29:00 AM at a low volume. At 2:48:35 AM, you can clearly tell the volume went to max volume. Wow...The music played for an hour and a half at max volume before I woke up. My poor neighbors!

 

According to ChatGPT:

Most Likely Cause: Sonos Firmware Restart + “Resume Last Source” Bug/Behavior

Sonos devices periodically:

  • auto-update firmware overnight
  • restart after network interruptions
  • reconnect after router DHCP lease renewals

When that happens, some Sonos units resume the last streaming source, especially Pandora.

Normally volume should stay where it was — but there is a known edge-case behavior where the Amp:

  • restores volume incorrectly
  • restores previous session volume instead of last-used volume
  • or briefly jumps to max before stabilizing

Pandora is one of the most commonly reported services involved in spontaneous resume events.

Why 4:30 AM?
Because Sonos typically performs:

  • updates
  • service refresh
  • cloud token renewal
    during overnight maintenance windows.

 

Also, I have 14 zones. Why is it only the outside Sonos Amp that decides to blast music in the middle of the night?

To date, and I’m not sure where ChatGPT is getting this information, there has been zero instances of this tied back to Sonos software or Sonos updates at all. That’s not to say that yours isn’t the first, just that all previous cases have been other sources.

Unfortunately, this community does not have access to the data that is contained in diagnostics, while we can theorize, we can’t be definitive. Sending in the data to Sonos, then calling in is the only true way to identify where the commands come from.

    I assume that all of your devices running a SONOS controller should have been sleeping when the AMP started playing. Was the SONOS controller the active App on any of these devices?

    i suggest that you submit a diagnostic when you discover the AMP has started. Even though some of the details may begin to scroll away after 10 minutes, there should be some useful data available.

    Craigski’s speculation is interesting. A diagnostic should indicate that play was started from the front panel. Continuing along this thought, there could be a hardware issue with the AMP that generates stray Play and Volume commands from its front panel. While a bit messy, physically and with your time, if you have another AMP in the system you could swap speaker connections and Room setup with another AMP. If the issue then moves, it’s obvious that it’s an issue with the AMP — and your neighbors will be spared while you work through the issue.

    ChatGPT quotes me as repeatedly saying “If you don’t like it, go back to CD’s/radio/etc.” on this site. 

    Something I’ve never, ever, ever stated.  Not even once.

      Keep in mind that the majority of AIs out there are programmed to answer questions, if a correct answer can't be found the AI will often hallucinate an answer rather than admitting it doesn'thave one. This is a common AI issue, not just Sonos.

      Funny to us sitting on the sidelines with a bag of popcorn, but often disastrous for the poor user trusting it.

      Tl/Dr? -- Don't bet the farm on your AI buddies answer.

        The Amp is not just sitting on the patio exposed to the elements outside, it is installed indoors. 

        Any cables near the front of Amp? I know from experience if earthed mains cables are near the play/pause they can cause the touch button to operate. Disable Touch controls in settings if they are not used on an Amp that is tucked away.

        The touch controls were disabled upon installation. Good suggestion though.
