Strange Tone/Noise playing randomly on the Sonos speaker systems, weekend of May 12-13. 2018

Came home at about 11:00 pm on June 22. From outside of our house we could here very loud rapid sequence tonal sounds. Entered house and found one of our paired Sonos Ones at maximum volume emitting sounds almost like synthesizer notes. Had to unplug the unit to make it stop.

Without a diagnostic, it's hard to tell what happened. It's certainly not a normal thing to find. Must have been disconcerting.

I ran the diagnostic. If I plug in the second Sonos One it makes the odd sounds and then my other sonos shuts off. So at this point it is obviously useless. Guess I'll try to return it.

Did you call in to Sonos with the diagnostic number? As indicated in the Diagnostics - How do they work? thread they don't look at them unless prompted.

I got this same thing and now I am getting the random beeps. Has anyone heard an answer yet?

Without any data to support this, it's overly easy to suggest that there is some sort of interference coming over the wifi that's being carried to the speaker causing it to reproduce the sound. If you, or your clients, are able to submit a system diagnostic within 10 minutes or so of experiencing it, it's going to be much easier for someone one from Sonos to track the issue down, with real data, rather than just anecdotal evidence.

The few cases I've seen on speakers that were connected to TVs have ended up being a signal being sent by the TV when the TV has shut down, and the speaker has just been playing that "errant" signal. Since the TV considers itself "off", it just requires a change in the settings for power down to remove this "clearing of the throat" that the TV has been doing. Don't remember the real specifics, but it was happening, as I recall, ten to fifteen minutes after the TV had been "turned off". But this is on TV connected speakers, and not general music speakers.

Hi Bruce,
Thanks for your reply.

I understand your desire for extra information. I worked in technical support for years.
This is a Sonos Play, its line-in is connected to a TV. It has been set up like this for months, as I have been reviewing this system for installation for my clients'. This is the first occurrence of this situation that has happened... at least when I have been home to hear it.
At the time the TV was off, and had been off for at least 20 hours.

If this happens again at my house I will run a diagnostic for you.


Thanks.

Don't run it for me, I can't see diagnostics. Run it for the Sonos techs, who can.

But thanks 🙂
