App Volume Malfunction

No direct advice here, but if I can recommend to you, then next time it occurs, within 10 minutes you should submit a system diagnostic and post the number here. That would give the techs at Sonos an opportunity to look at the log files from your system to see if there's something odd going on. It might be helpful to let them know which particular phone you're using (iPhone? Android?)

The other option would be if you have a pet who might be sitting on a speaker, and pressing the volume button for you. I've heard of that happening, never experienced it myself, my cat's too old to get up on top of a speaker. 🙂

Thanks Bruce,

I was trying to find how to run the system diagnostic this morning but I couldn't find it. I'm sure theres info here to point me in the right direction. Its definitely not the cat :o)

Thanks again for the reply

It would be interesting to know more once you do; I have never heard of this fault till now. I do have to wait at times for it to move from a previously set level, but this is something else.

You're most welcome, Nick. Hope they can find something out. Since it's not the cat... :)

But I share Kumar's hope that you come back and let us know, once it's figured out. It's a real mystery for us right now.

Thanks everyone. I'll be sure to submit a diagnostic the next time it happens... hopefully that is never 😃

I was refelting the shed roof a while ago with my phone in my pocket. At the time, the volume buttons on my phone could control the Sonos volume even with the screen off and the phone locked. The four grouped zones at the time all went to max volume and I didn't realise until it happened for the third time that it was every time I leaned to the left to hammer another nail in!

Thanks for the reply. This definitely isn't that either. I've been looking directly at the volume as it slides itself down to zero, I've then moved it back up with my finger to a normal level and as soon as I let go it slowly moved back down to zero. I've repeated this multiple time in a row. It's like a ghost in the machine.

It's like a ghost in the machine.
Indeed. Perhaps it is a phone glitch. Power that off once and when you are on again, delete/reinstall the controller app and see if that exorcises it! After sending the diagnostic.

I envision a cat in the corner playing with an ipad.... :D


I have read a number of posts with similar experience which appeared to derive from a variety of different reasons...

I recall one that was linked to a PlayBar that had an IR device fault that was sending a signal to the playbar... (solved it originally by covering the ir receiver on the PlayBar to discern that was the problem)

Another where a volume on a player was depressed... or where it appeared the volume button was stuck (no confirmation on that as I recall)

Another where someone asked if perhaps the volume button on the controller (ipad or iphone or whatever it was) was stuck or depressed

Another somewhat related, and hilarious, thread that suggested someone could actually have been logged into the router and be controlling the system if they download the Sonos app...

Hope some of these help troubleshoot....
