Sonos App volume control

Hi there, alant78. Thanks for posting and welcome to the Community. Can you tell us a little more about how you are adjusting the volume? Are you using the side hardware control buttons or are you using the volume slider in the Sonos Controller app? Thanks for clarifying.

Hi Keith, both reacts the same for my iPhone. Is it normal?

Hi Keith thanks for your advice. I re-installed the app again and the issue is gone. Tks Again

I've figured out that I'm having the same issue, on both iPhone (iPhone 5/iOS 10.3.3) and Sonos 8.4) and iPad (iPad Mini/iOS 11.3 and Sonos 8.4): Adjust the music volume using the screen slider and the device volume changes, too. Even better, if I change the volume on the iPad and go to the phone, the phone's volume changes, and vice-versa. And yet one better: if I use the desktop app and change the music volume, the iPhone and iPad both also track. The only difference seems to be that the portable devices' hardware follow the Sonos app slider, where the desktop hardware doesn't follow the app's slider.
I've gone into settings and disabled hardware control on both. I've deleted and reinstalled the app on both devices. I can't say for sure how long this has been going on, though I've been aware that "something" seemed to be changing the phone volume and I've occasionally missed calls and messages because the ringer volume was oddly low. Any other ideas how to fix this?

Hi there, helarson. Thanks for posting and welcome to the Community. If you are still having troubles with this, I would recommend giving our support technicians a call to troubleshoot this in real time. While they aren't able to set up a remote session to a mobile device, they can gather more information and get a closer look at what is going on. Thanks!

When I started using the Sonos app I could use my Android phone to play videos or music on Youtube or other app and stream it to bluetooth speaker and use my phone's hardware button AND simultaneously be streaming music via the Connect to my hifi and control the volume from within the Sonos app and the 2 systems were independent of each other. I was very impressedby Sonos' brilliance!
Then it stopped doing that and when I adjusted the ringer volume on my phone it would change the volume on my music even when the Sonos app wasn't open.
This was annoying,but since Sonos keeps pushing updates every second week I thought they'd address it. Too late for me I'm afraid. This morning the music was playing at low volume. My young fella was playing Angry Birds on the phone with the Sonos app obvioudly closed and when he increased the game volume the music volume went up to ear splitting levels and by the time I ran to the room there was the stench of burnt electronics. Both the midrange drivers on my pair of $20 000 speakers are blown and the $10 000 subwoofer is producing a rattle that wasn't there before. I love my music system with a passion and I'm mighty PISSED OFF at Sonos for this!
I'm a peaceful and law abiding citizen who always acts with kindness and respect to his fellow man. I don't even get a parking ticket. But right now I'm in an unbelievably FILTHY mood.
If there's anyone who can suggest what legal options I could pursue I'm all ears....

I'm sure that before previous updates, if sonos app was open in the background on my android phone, adjusting the volume control on my phone would change sonos player volume. It only works now when I have the sonos app open and active.

What were the £20k speakers out of interest? Did you get this resolved? Not sure how you play sonos through separate speakers though given its a speaker system, and sonos don't make hardware in that price range. I've had some good kit in the past (Hegel, ATC, ProAc, Roksan etc) and with all of those systems either my ears would bleed or the amp would have over driven and blown the tweeters. I ran some of them to max vol and discovered what 120dB is like in a closed room, but no burnt drivers.

The only Sonos device capable of driving passive speakers and a 3rd party sub at the time of that post was a Connect:Amp. So the real question to ask is why in the world would anyone spend £20k on speakers that can't even handle 55 watts of power?

Or, as I suspect, the story is a big ol whopper.
