Changes to volume mapping and impact on Sub output

 

Thank you for your feedback regarding the recent 14.12 software update with Enhanced Clarity for Arc

 

In this update, we made a change to Arc’s audio profile to improve dialogue clarity and the overall sound experience. This change is based on feedback from our listeners in the field and brings Arc in line with our other Home Theater products, resulting in a more accurate representation of the sound as intended by the content creator. 

 

The updated tuning adjusts the spectral balance of Arc+Sub to achieve a more accurate representation of the sound and an improved sound experience. While the Arc+Sub output capability remains the same,  the mapping of volume across the 0-100% range has been adjusted with this release which means low and mid volume levels are relatively lower compared to the previous tuning so you may need to adjust the volume slider to achieve your pre-update volume level. The maximum volume and bass output are unchanged. We acknowledge that this change was not made more clear in the release notes and in the future we’ll be sure to make sure we communicate these rare changes more effectively. 

 

Please note, we have identified an issue for some users of Arc, Beam and Ray whose configuration includes a Sub (with or without surrounds), who may find their Sub output is lower than desired after performing a new Trueplay tuning. 

 

Users with Beam or Ray bonded with Sub can increase the Sub level for a more powerful low-end response, however this won’t have the same impact for Arc users. Customers using Arc bonded with a Sub (and/or surrounds) who find their Sub output is lower than desired following performing a new Trueplay tuning, should temporarily disable Trueplay on Arc until this is addressed by an upcoming software update. 

 

Trueplay tunings for Home Theater configurations without a bonded Sub are unaffected, including standalone soundbars and those bonded with surrounds only.

Moderation edit:

With the 14.18 software update, the above mentioned issues have been addressed, and the Enhanced Clarity for Arc adjustments are retained. There was a clear preference within our community for the previous volume settings, and these have been restored. This will be apparent immediately after updating to 14.18. The Trueplay issue has been fixed. Customers who experienced a lower Sub level after performing Trueplay after updating to 14.12 will need to update their systems and then perform a new Trueplay tuning in order to address these improvements in their system. Customers will hear a more powerful low end response, meaning any Sub level adjustments made after 14.12 should no longer be required.

I’m assuming red & yellow are different as the phones were not in exact same positions when waved for each of the Trueplays, ie if you did 2 Trueplays with same phone you would still see a slight difference?

Mic is on the same position, and i walked the same way. I wanted to see if there is any difference between the phones, because i liked the sound more yesterday when i used SE 2 for first time.
Still the low frequencies are reduced (the sub peak is at 85HZ), but the overall sound is better than the previous firmware. At least there are more lower frequencies.
I do not commit anyone to my measurements nor do I claim to be right because every room is different. I decided to share my impressions, because it may help some of you while we wait for the final fix.

I agree, and  of course, every pair of ears will also have a different frequency response.

 


I know Sonos has clearly said that the updates has not addressed the sub issue, but with true play on mine does sound a little punchier than before. The bass sounds a little more richer and fuller. Also, I do have a subwoofer on both sides of the rooms which are set to 0. Having 2  subs will also increase the fullness and richness of the bass. I’m still waiting for Sonos to directly release a software that addresses  this ongoing issue though.

I do tend to agree on this one; sub sounds a bit better but the Arc isnt 100% at all. Might be placebo.


Coincidentally stumpled upon this thread. My Arc/2xOne/Sub combination is still on 14.8 while my iPhone app is on 14.14, so I expect I should wait this one out? ;)

Hell yeh!

I hate to say this but! I have tested several bass test songs now AND the bass is better with trueplay on. I have NOT Done a new trueplay with 14.16 though.

The bass is no way near as good as 14.10 but better with trueplay on for me right now.

 

I can feel it in my ass sittning in the sofa comparing trueplay on/off…

Unfortunately for me the opposite is true, I am more concerned about the sound signature than the bass though 😩


Switching off trueplay makes pretty much no difference in my case. The lower bass is still completely absent. So I don’t even have a workaround. This is a terrible customer experience, and I cannot possibly recommend Sonos to anyone ever again.

I had the same after I ran patch 14.16. This morning I did a factory reset on the Arc, one SL’s and Sub gen 3 and re-added everything again. 
Now with Trueplay off, it’s acceptable, but far from good. Haven’t tried Trueplay yet. 


TruePlay on or TruePlay off, you can still adjust your own sound profile in the Sonos Controller, and bump up the bass.

I definitely agree. But I know others may not be experiencing the same.

What sub-level are you on? In my setup with Trueplay off, sub-level -2 is loud enough and lets the couch rumble at volume level 60. With Trueplay enabled, I need to set sub-level at +10 to get near the same effect. But I do notice the bass is more “muddy”, probably because the low-bass is far behind the mid-bass due to the Trueplay-bug. When Trueplay is disabled, the bass feels more punchy and cleaner, the way it should. With Trueplay enabled, it seems there is a much wider soundstage from the Arc. So I have to choose between a muddy bass and a wider soundstage.

I will agree with this. In my first experience with the issue that’s exactly what I found to be the case. With true play on the ARC rises above everything else including my ONES. Everything seems more balanced including the bass with true play off. But recently it’s become less obvious like I described earlier. I will agree like you said the bass is more cleaner and fuller with true play off still. The best solution is for true play to be enabled and still have that rich clean soundstage like before in version 14.10.


I will give it another go. If I do understand correctly you sacrifice the clean and full bass for a wider soundstage. And since patch 14.16 it seems the problem with the Sub is less-worse than before?


Difference in the new software are so minimal that whatever you perceive as better is just a placebo effect guys. Just look at the frequency sweep in Peter's last video.

 


Just another voice to say the sub update is definitely broken.

I have an Arc, 2x One SLs and the Sub Gen 3. I don’t have Trueplay enabled. 

I’ve just been doing some A/B and there’s definitely something wrong. 

With sub audio set to default (0), I actually get better more prominent low end with the sub OFF. It’s immediately noticeable if I play a low end heavy track. I have to turn the Sub volume up to +6 to get roughly what I was hearing pre-update. You can flick it on and off while tracks are playing.

When you enable the sub it ‘takes over’ the low end from the Arc/Ones essentially automating crossover. However, following the update the sub is being so underpowered that by doing this you’re just losing the low end completely. 

This is a dedicated £750 sub. It’s not meant to be subtle, it should have noticeable bass which it used to. I’ve spoken to Sonos support, even they are admitting it’s still a problem guys. 


I just did factory reset for my Sub gen 3 and Arc. That’s weird as it seems to be slightly better than before (both with trueplay off). I can feel more bass for sure.

Yes, that’s correct but I do alternate depending on what I’m listening to.

Yes, that may be true also. I didn’t rerun true play so there  might be a minimal difference in audio after that even though it may be minimal. I did retune it farther away, or hotter from the speakers which may make a little bit of a difference..

I think the majority of us will agree with you, including myself that the sub is still broken. But in the interim, we are just trying to improve the sound quality as best as possible until it’s completely fixed.

I had this issue - split your Ones and Sub into one ‘room’, and put the Arc in another ‘room’, for music you will get 14.10 type sound playing both rooms simultaneously.  You wont get the lack of bass issue with the ones driving the Sub.  I have the Arc volume slightly above the ones/sub, I can enjoy music again until they fix this mess properly. 

 

This should also work for TV too via the HDMI (tested mine via Creative X4 external DAC to PC and I can game in 5.1 audio, even though the system is split into two virtual rooms, so same principle should hold true for TV connection, I would think. 

 

Only thing this wont fix is allowing you to play Atmos music via Amazon Music - multiroom playback stops you from having the ability to select Atmos (prob due to the 2x ones + sub as a standalone) and UHD tracks, but to be honest HD sounds amazing anyway.  

 

Hope the above helps anyone wanting a short term music fix!!!! Literally cant believe the difference - my sub is now on +2 (from +15 and still sounded rubbish)  and the bass is thundering away on my music again properly as it should be!

This is a really good idea. I think I’m going to give it a try just to see how it works.
