14.12 Update

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.

If you would like any assistance adjusting the sound of your Home Theater setup, the community is here to help. You can also contact Sonos support.

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.

Yeah Yeah I don’t need to dial up the volume up to 50 to hear the dialogue especially on streaming services.

I have to agree with everyone on this thread. I think there’s a major improvement in how it sounds. I’m not sure if it’s 14.10 but it’s significantly better and I love the new song profile.

Just installed the update and re-ran TruePlay. Low end is definitely back - I’ve got rumble again with the Sub output set to 0 and TruePlay on. Night and day difference between this and the 14.12 update.

After an evening watching both streaming and bluray movies I have found an improvement over the previous patches

Though I don't think it is totally fixed all the issues it is a step in the right direction 😊

Truplay is now usable let us hope sonos build on this and we don't return to previous mistakes

Any improvements with 14.18 for those without a sub?

I bought a stereo pair of One SLs last week and notice that the bass is significantly cut after running Trueplay.

Hi all,

Thank you for your continued discussion. We’re really happy to be able to tell you that today we’ll release an update that will include fixes to the issues that resulted from the 14.12 software update with Enhanced Clarity for Arc.In the 14.12 release, we made a change to Arc’s sound profile to improve dialogue clarity and the overall sound experience. Since that update, some users whose configuration included a Sub have experienced two issues:

Users of Arc would find the same volume settings resulted in lower output volume. Whilst the maximum volume and bass capabilities were unchanged, volume settings in the lower regions resulted in a quieter sound than before the update
Users of Arc, Beam and Ray would find their Sub output is lower than desired after performing a new Trueplay tuning.

(Home theatre configurations without a Sub were unaffected, including standalone soundbars and those bonded with surrounds only)

With the 14.18 software update, both of these 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.

@Corry P

Thanks for the post the patch has restored some of the sound but the sound signature is still overly treble in nature for my ears is this now permanent?

If so I will be disappointed

Hi @skullc

If you still have an issue with the sound of your Arc, I can only recommend you get in touch with our technical support team for the issue to be documented.

Before doing so, I would recommend perhaps tuning with a different device - if that’s an option for you, and if you haven’t tried already.

I hope this helps.
