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

    Thanks for doing this analysis! It provides actual data to what many of us are experiencing. I have noticed that with trueplay off the system sounds better and closer to what it was before the update. But not quite as powerful still. Even with bass/sub audio all the way up.

      It certainly seems possible that they introduced some undesirable side effects due to the number of complaints on Reddit about the anemic bass after the 14.12 update. I've never once bumped my sub level above "0" until the 14.12 update. Something seems broken.

        I also noticed that something is wrong with the sound after 14.12

        I put the volume way higher than before and I still don’t get the same results that I used to.

          I wonder if this has been done before the sale of the mini sub begins, since the mini sub can't handle those low frequency…

            Hi. I have the same problem after last update 14.12. After Trueplay I had to set Sub at +10 in order to hear barely some bass. These bugs could not happed in this price range. Now sonos sound like s…

              This is sad to read, I can’t say I have noticed the lower bass yet with my sub, as not watched any sub heavy material at a decent level.

              But if this is indeed the case, why are recent updates releasing with these big bugs, sort it out Sonos!

              If that is the case and they are crippling systems to support new hardware then that doesn't bode well for the future.

              I was looking at an Arc but not a chance after all the trouble people have been having since 14.06, and it just keeps getting worse.

                They fixed the issue since 14.06.

                Then apparently miss-tuned the sub in this new 14.12

                Just the nature of patching - I don’t mind being bleeding edge (wading through bugs), but the idea with software updates is - if someone add’s features, don’t update till you see the patch that fixes those features ;)

                  2 months with the Sub and Surrounds dropping out would have been annoying to say the least, then to mess the Sub up not long after isn't great customer service (to me anyway).

                  S2 seems far to update happy for me unfortunately, not even Sonos headphones could drag me over now.
