Volume of system changed

I didn’t think that Sonos hardware allows the setting of Static IP addresses? Is this something new?

No, Sonos has always supported that using DHCP from your router's settings. There should be a help option for DHCP Settings on most router's, others you will need the manual if you can't see how to do it.

Ah ok, so does that mean that it’s the router that does the static ip address allocation?

Please exvuse me if I’m asking dumb questions :-)

No yours are not dumb questions, I have never heard of DHCP🤣

Stupid forum just ate a 15 minute answer. When will I remember to select-all and copy before posting.

Much shorter version, sorry.

The router contains a DHCP server that assigns IPv4 addresses to all devices that request them. It will assign one it picks or you can set a static, aka reserved, address that will be used.

There is a setting in some devices, not Sonos, that allows an address to be set internally and then DHCP isn't used.

Ah thanks Stanley. 👍👍👍

Hi,

I have the exact problem since the last update about 2 weeks ago (start of November 2025) with the 92-0-70280.

- All my Sonos speakers (Sonos Arc Ultra, Sub Mini, Era 100 and Sonos One) : everytime i turn on TV or Music since the update, the volume starts at 60% when I'm usually around 15%.. So you can picture the huge mess everytime I turn on TV and music.

- Arc Ultra with TV : while watching TV, the sound suddenly stops ( volume is set at 0%), i have to increase the volume to have the sound back. 

Those problems never happen before the last update. I have to admit that the sound quality is much better since the update but thoses problems want me to stop using those speakers. 

Hope a new update will come soon and fix everything. Unless someone have a quick fix? (Having a static IP is not one lol)

That’s odd. I don’t have an Ultra, but two Arcs, and both of them ‘resume’ at the same level of volume when they are ‘turned on’. Have you submitted a system diagnostic within 10 minutes of experiencing this problem, and called Sonos Support to discuss it? Don’t post the resulting diagnostic number here, they get sensitive about GDPR.

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 Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

It does make me wonder if there’s some remote control that is messing with the TV’s volume (which is where the Arc Ultra gets its volume commands from. Which also begs the question, have you checked the TV for an update to its firmware?
What is a 92-0-70280?

Hey Airgetlam,

For the record, the 60% volume issue concerns not only the Arc Ultra once i'm turning the system on, but all the Sonos speakers. It didn't happen before the last update.

Before the update, the volume stayed still from the last use. TV has no update since a while, but as I was saying, the 60% volume start concerns all the Sonos Speakers i have, not only the Arc Ultra connected to TV.

Don't think the TV remote is concerned since it never happened before the update and it concerns all the speakers, even the ones not connected to the TV.

92.0.70.280 is the last version of the firmware that was updated 2 weeks ago, since the problems started.

Thank you for the advice! I've never tried the system diagnosis. Good it does exist, but still takes time.

Interesting, certainly. The only volume commands sent to Sonos are from a controller, or the buttons on the devices. If you’re able to catch it within 10 minutes, I suspect the diagnostic should be able to say which kind of device it was generated from. As an aside, I’ve long since lost my cat, which always enjoyed sitting on my speakers when she could, due to their warmth, and sometimes actuated the volume controls. I learned at that time to turn off all buttons on my Sonos devices, so that there couldn’t be external inputs from dusting, cats, or anything else (including errors!). But then I don’t ever use that method of control, my situation doesn’t fit all use cases, it just works for me. 

But, as I say, the diagnostic will hopefully catch the reason for the volume change. I don’t know a lot about the data storage in a diagnostic, if there’s nothing else going on, I suppose it is possible the data is held for longer. Your best bet is to check with Sonos, they’re the only ones, as far as I’m aware, who have the ability to read that data. Fortunately, your call doesn’t have to be in that 10 minute window, the data gets stored on Sonos servers to be pulled up when you call in, and supply that number. 

I’m not experiencing this on any of the 7 or 8 rooms, with 20 plus speakers, so it makes me think, at least, that it is a local issue, but I don’t know that for a fact. I’d love it if you were to post back about what you find out, either way.
