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

I had this happen to me today but I have Apple Music and it started playing music on a grouped pair of sonos ones and a sonos move that were all grouped together previously… it started playing some random strange song on Apple Music at about 1:45am tonight. I submitted diagnostics number 763298157. Can someone please help or look in to this? This has never happened to me before so would like to know what happened!!

 Hi @ashleywntr, thanks for providing those diagnostics.

I’ve tested this on my own system and I have been able to replicate this behaviour - just to confirm, does this only occur if when the Beam is grouped, it is acting as the group coordinator? i.e. the Beam is the first room listed in the group?

It looks like when the Beam leaves the group, the stream is passed on to the next player and the stream gets unpaused - in any case I’ll pass this on to the tech leads to see if this is something they are aware of :)

[Edit - I have just heard back from the tech leads and we are aware of this issue - we’re currently working with Spotify to get it fixed, however I don’t have an ETA that I can share right now]

So, neither case is applicable from your previous post. 

I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your Sonos system and network.

In your first case, your system is not automatically resuming music that was stopped many hours ago. Instead, your system is receiving a command from the still connected Spotify Connect device to resume music playback, or start a fresh song. In your second case, the TV is starting to send a signal to the Sonos soundbar, which is set to autoplay, and starts playback. 

In both cases, Sonos is acting as a receiver of data, and doing exactly what it has been ‘told/programmed’ to do.

Thanks v much. 

If you’re in a beta program, as your screenshot suggests, you should not be posting here. 

I do not think you can. But Sonos can see all diagnoses sent from your account. Contact them.

Most curious. John’s suggestions are outstanding, and I’d also suggest using the TV to force a check for a software update to its firmware. Leave the automatic process turned off, but double check to see if there is an un-applied update. 

Frankly, I’d be tempted to suggest a reboot of the TV’s OS as well, by unplugging it from the wall for a least 3 minutes. 

If it’s not clear, I think the Sonos is doing what it is told to do, as normal, and the issue appears to be that the TV is generating a signal when it shouldn’t. The Sonos is essentially a ‘dumb’ device, and when something is sent to it, the Autoplay function works, and it plays whatever signal is being sent. 

Note: this could change if it turns out in that diagnostic if the command is coming from elsewhere, and it’s not the TV autoplay being engaged, but instead a music station. 

Sure, should've added all that in my initial post, reminder for next time: don't write a message from bed while falling asleep.

The Beam is wired to a Philips 58PUS8505 Android TV through an HDMI ARC port. When it starts playing it almost always is a TV station as source, however it does not fit the TV station that was watched before turning the TV and the Beam off. The TV screen stays black and the Beam turns itself off after about 10 to 15 seconds.

Yesterday evening the TV was used for watching Netflix and YouTube, both through the installed Apps on the TV, no TV station at all.

Regarding the TV station as source I say almost always since I can't 100% guarantee that it never was a music channel source in the past. However, if it was a music channel source at least it was not a song anyone in my wifi played before.

When I first investigated this issue I found a few threads that suggested turning off the auto update functionality of the TV might help since it can turn itself on (while leaving the screen black) to check for updates. This didn't help at all.

I can also rule out any animals sitting on the Beam as I don't own animals right now and the only child in the house is sound asleep in his bed when the Beam turns on. The touch controls are turned off in the app and the child has no wireless device in his room that could connect to the Beam.

The Beam is in a group with two Ikea Symfonisk speakers acting as rear channels. Those stay quiet when the Beam gets turned on (or are so quiet I don't notice them). In the app I configured my living room setup to have "TV Autoplay" active as well ws "No group when Autoplay".

Hello,

I'd like to get some insight into what keeps turning on my Beam randomly up to twice a day. Last time it happened was around 10min ago, after I switched my TV off maybe 20min ago. Most of the time the audio suggests that a random tv station is playing, as far as I remember for me it never played music.

Diagnostic code from the incident 10min ago: 508331929
