S2 Update 14.12 Sub Issues

Hello,

With the recent 14.12 S2 Update there is a bug in the sub settings when using Trueplay, and I've pinpointed the problem. I wanted to pass along this information to the company to ensure that the specifics of the issue are known.

It’s likely that most people may not notice this, or bother asking Sonos about it, but this is a real difference between 14.12 and the previous versions.

My current setup has an Arc, Sub(Gen1), and 2 Play1's.
- Using a white noise generator to review these differences.
- I'm controlling the sub settings on my iPad Pro while recording on my iPhone 12 Pro Max.
- I've run Trueplay twice since the update, and get the same results both times.
  - Both Trueplay runs were with my iPhone as my iPad Pro does not have support yet.
Once updated to 14.12, you are prompted to re-run Trueplay. But Trueplay has a bug in this new update.
I tested the frequencies with Trueplay On and then Off without changing the volume on the App.
- The only setting modified is the "Sub Audio" setting that ranges from -15 to +15
These differences are absolutely unique to the 14.12 update
- I did not take pics, but have done similar tests before and the sub settings always increase/decrease all of the frequencies below the crossover
- In previous versions, 40hz was always the highest db of any frequency when bossting the sub volume.

Trueplay On with Bass and Treble set to 0:

Sub = 0:
- There is about a 4-5db reduction in the 30-60hz range and a boost in the 60-80hz range compared to Trueplay off
Sub = +15:
- Here is where you see the issue. Sub 50hz doesn't change much at all even boosting the sub setting to the max
- There is a huge boost in the 60-80hz range where it is now the dominate frequency range of the sub

Trueplay Off with Bass, and Treble set to 0:

Sub = 0
- You can already see a difference in that the <50hz frequencies are higher and it's a pretty flat wave.
Sub = +15
- Notice that now the dominate frequency range is the 35-50hz.
- The 60-80hz is still boosted, but it does not ever overtake the lower frequencies
Lastly, here is a grouped view showing these pictures side by side so you can really see the difference.
- It also includes going -15 on the sub
Could it be a High Pass Filter setting that is getting triggered when you run TruePlay?
If you do not like the way your system sounds after 14.12, turn off Trueplay.
- It will not be as good as what you are used to as Trueplay will adjust more to your room and leave less peaks/valleys throughout the spectrum.
- But it will still be more like what you are used to hearing.

I can provide more information if needed, but hopefully this helps pinpoint the issue for everyone.

Thank you for your time,

Robert

I have noticed my system no longer sounds the same, more dull. Hard to explain. Is there any way to revert to the previous version?

Despite years and years of requests, Sonos has not yet made available a method to “roll back” to a previous version. I’d assume it’s hard to do so, and they’ve not invested time in making it more easy.

Have you rerun TruePlay as suggested in the original post about this update?

Have you contacted Sonos support with your diagnostics?

Damn it, not this again. We were just out of the 14.6 nightmare and you shove this on our throats. I should be mad at myself for manually updating despite having the auto updates turned off.

Now I am genuinely concerned about their software engineering quality control. I really hope this doesn't take another 60+ pages of comments and troubleshooting for them to acknowledge this. I'm beyond pissed.

Excellent report @ropfeil Thank you!

Do you by any chance have frequency response graphs from before the 14.12 update?
Myself and many others have noticed that the sound profile of the Arc (with and without Sub) has become flat and unbalanced in general and that’s on top of the obvious bass issue. Different people experience it differently: reduction in volume, unbalanced channels, exaggerated mid/high frequencies, loss in detail, overpowering vocals and dialogue, etc. There is another tread on the forum with more reports here:

As far as I'm concerned, they never acknowledged the dropout issue with 14.6. They made “improvements” that just so happened to fix the issue hundreds of people were reporting. I expect the same treatment with this. Deny, avoid, and we are left hoping for a fix in every release.

Prove me wrong Sonos.

As this is not the first issue from software updates and as their has been silence from the firm if and when my products stop working I will not be replacing them like for like.

I will look at other firms products it's not the fault but the lack of admission of the issues that troubles me and I find that sad
