Why does my Sonos system turn itself on, playing a random song!?

I didn’t have any alarms on Alexa either. Logged off on everythig on spotify.com and changed the password. Haven’t had any new cases the last two days so that hopefully solved it.

This has been happening to me since installing my arc and one SLs 

diagnostic : 1415100533

Can anybody help ?

Hi @Gremlinsky, 

Thanks for reaching out to the Sonos Community and letting us know about your concern. Apologies for the late response. Let me help you with this.

Upon checking the diagnostic, there are AirPlay and Spotify direct sessions detected in the report. These sessions can be performed directly played from the mobile device or Spotify app to start the playback on Sonos devices without using the Sonos app.

Are there other devices that you're using to stream music on your Sonos speakers?
How often do you experience this with your Sonos devices? Do you have a specific time?

I'd like to recommend that in case you encountered the issue is to submit a diagnostic and let us know the confirmation number for us to check. You can also contact our phone support team to perform real-time troubleshooting to determine what's causing the issue. Please let us know if you have any further questions or concerns, we'll be glad to assist you. 

Tonight’s diagnostic : 1646806054

seems to happen about 10 minutes after we’ve turned the tv and PlayStation off following watching Netflix on the PS4. 
 

the things that are played we haven’t been listening to - no idea what it was tonight but it comes on really loudly - sounded like some sort of documentary. 
In the past we’ve had some U2 playing, some teenage kick (the undertones) - nine of which we’ve been listening to - it starts midway through the songs  

it plays for about 15 seconds really loudly then goes off. 
 

if it keeps happening I’m afraid I’ll have to return my whole Sonos setup.

And one from today. 
I asked Alexa to play something in the kitchen (which would have played from Spotify) and then moved into the lounge and longed pressed the play button on my lounge speaker to play the music in the kitchen also in the lounge. 
this worked well - but I’ve just had my music interrupted by what sounded like a radio station. It played for about 15 second then went off - the music is now back to playing only from the kitchen. 
 

id had the tv and switch on about 10 minutes ago - so it does seem there might be a connection here with turning the tv off and then something paying on the Arc after about 10 mins. 
 

it’s very very odd.

Hi @Gremlinsky, 

Thanks for updating us and for submitting diagnostic reports. Upon checking,  I'm still seeing AirPlay and Spotify direct sessions in the report that possibly causing this.

Let me suggest the next troubleshooting steps you can do. 

• Sequential reboot to refresh your network and all your Sonos devices connection.
  • Unplug your network devices (modem, router, any wireless access points on the network) from the power and wait for 60 full seconds before you plug it back in.
  • Once the router is back online, unplug all your Sonos devices from the power.
  • Please wait 15 seconds before you plug back them back in.
  • Force close the Sonos app from your iOS or Android device.
  • When the status light on your Sonos speakers are solid white, get back on the Sonos app and check if you're connected.
  • Test playback from and observe Sonos performance.

If it's still doesn't work, you may need to contact our phone support team to look into this. Our phone support has the tools to check what's going on in your system and to remotely access your device to address the issue. 

Please let me know if you have any further questions or concerns, I'll be glad to assist you. 

Hi there - reset everything as above. 
happened again 10 mins after turning the tv and PlayStation off 

diagnostic : 319272792

This has happened to me in the wee hours of the morn off and on over the past month. 
 

when checking the Sonos app after , it first showed Spotify as the culprit. So I removed Spotify from my Sonos. 
 

now it is happening again and it lists Amazon alexa as the source. I disabled my Sonos speaker from being played by my Alexa and it is still happening. 
 

it is playing music I don’t listen to so I’m wondering if somehow a different Alexa is doing it? I live in an apartment building. 
 

anyway, here is my diagnostic: 322387237

any help would be great as I’m about to throw the damn thing out the window
