Spotify volume decreased?

Haven’t noticed any change.

I don't understand. In an Era 100 before around volume, now around volume 50. It's very strange.

Have you called Sonos Support directly to discuss it?

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 network and Sonos system.

I'll call support! Hoping it's just me, but wanted to check if it's a wider issue?

Doesn’t appear to be, there have been no ‘me too’ posts in this thread, or separate threads about it. 

Yes, I have exactly this problem with Era 100s, Beam Gen 2 and Symfonisk Frames. Only on Spotify and only since a couple of weeks ago. I get the geeling the quality reduced too, but I can't be 100% sure on that.

Sonos Radio appears to work fine so must be something specific to Spotify..

I don’t imagine it would make a difference but going to suggest it - is it worth turning on or off Enable Audio Normalisation in the Spotify app just in case it applies it to your whole account, even when streaming via the Sonos app, which impacts in some way the gain coming through?Maybe try with it on, and also with it off, and see if there is any difference - giving it time to kick in.

(This option has an effect when streaming directly to the speakers via Spotify Connect of course, but just wondering if there is some backend impact this option has too for streaming through the Sonos app...)

I am having the same issue. Volume needs to be turned to around 50 to be as loud as 25 used to be. Did you find a solution when you called support?

Over the years there have been many complaints about the output level vs the numeric setting. There are complaints about “too loud at low settings”, “louder than model XXX at the same number”, “I need to turn it up to XX, YY, ZZ and I should only need QQ”, etc. Eventually, the developers accommodate one complaint group and change the behavior (unannounced) of one or more models in an update. This immediately triggers complaints from the other groups. Eventually the developers side with another group in an update and the complaints shuffle.

One strong complaint, when the new required setting is higher than the former, is that the unit is “not as powerful as before”, because a higher number is required for their usual output. This is not strictly correct because the power output at 100 is still the same. Even if the acoustic output at a low setting is the same for all speakers, the speakers in large rooms will seem quieter. This identical output cannot be maintained at loud levels because the larger speakers can deliver more acoustic output. It would be silly to limit the acoustic output of the larger speakers to that of the smallest speaker.

Previously Spotify connect and Sonos app had no difference in quality and volume when set at the same level, prior I remember testing this so purely used Spotify connect given interface. Since the last week or so I noticed Spotify didn't sound as loud at my normal volume (20) had to turn up to 40 which would normally be very loud for everyday usage. The sound still wasnt as clear as I remember it, so Switch over to Sonos app and playing the same song it sounds like it used to and what I expected and volume range was correct could listen at 20 and 40 again was loud and clear. Hoping it is just a bug at this point. I don't want to stuck using Sonos app.
