For what its worth, I think this was mentioned elsewhere, If you ungroup the rooms then re-group them, the volume sliders start to work for each room. Well, at least they did for me. This was on the Windows 11 application. I hope it helps.

14.18.1 is just an App update for the “dots” bug on iOS. You can safely install this. 

Give TruePlay a retune after installing 14.18 - it’s a good sounding profile, the raw low end is not the same as no TP, however the overall sound is much improved, and the low end minus can be eq’d with the sub level; you’re using a TP sound profile for 14.16 (or whenever you last TP’d, if not).

I had turned TruePlay off after 14.10; I’m now using it as of 14.18.

I haven’t installed 14.18.1 - won’t until Peter Pee on YouTube gives his blessing, lol.

Well thousands of users would beg to differ.

Also, Peter said there was an issue, but it’s less pronounced if you turn off your volume limit. Get your facts straight...

Why are you even here if you arent having a problem? ***

That’s great to hear! Will have to remind anyone that has similar issues after an update to go ahead and power cycle the devices as an initial step.

Yeah they say 14.18, I think they may have done an update overnight as auto update is switched on

ill do a new trueplay and see what happens 

many thanks

Check in About my system and it’ll tell you what the speakers are running. 

Yes, but if you have auto-update enabled in the App, then in your case it ‘might’ not have been necessary as the speakers might have already updated… er.. automatically.

My sonos app first had me update the actual app in the google play store, then when I went back to the sonos app, it prompted me to update the speakers.

Yeah i have done that guys, when i check system updates it says im uptodate

But my speakers haven’t gone through the usual long updating process, that i thought they would do..?

Did your speakers go through the speaker update process with the 14.18 software update?

If you’ve not got auto update set, use Check in System/System updates/Check for updates. 

Have you simply updated the controller App and are still to update your speaker firmware, perhaps ?

I'm not to sure this issue has been fixed?

I've updated to 14.18, my app shows 14.18 in system info, but none of my speakers have done an update, and the sound profile is no different to the previous 14.16 software

Still lacking the base and volume issue, this is a 5.1 dual sub set up, can anyone advise?

It is fixed!

We have had official statement its fixed and even Peter Pee has done tests to show its fixed.

My experience was with 5s and a sub for music playback.

 However…….

 After much experimentation and frustration I tried a power cycle of all the speakers in that room.

Normal service and sound is back again.
 

So my advice to anyone not seeing improvements after 14.8, try a power cycle of all the speakers in that room. 

I think @bockersjv is talking about a different issue with the recent software update, if I’m not mistaken? It’s an issue he’s seeing with a stereo pair of Play:5 (gen2’s) bonded to a Sub. It appears having the ‘bonded’ Sub results in little, or no, Bass …and switching off the Sub restores the Bass.

Trueplay tuning apparently makes no difference to the issue he’s encountering.

It will be interesting to see if others with that same hardware setup report having a similar, or different, experience. I’ve not (yet) personally seen any similar reports.

Is this with Trueplay off? Retuning with Trueplay after the update has fixed the issues for many folks, myself included. If you use the previous tuning, before the update, it won’t sound any better, but after doing a fresh tune, it sounds great again.

"Lives ruined beyond repair” …? That’s also a ‘term’ I am unable to equate with, when it comes to a software issue with a Home speaker system, particularly considering everything else that is happening in the world these days.

Well according to most and Peter Pee..it isn’t an issue. Go back under your rock..

I assume others may go onto comment on that particular ‘bonded’ configuration @bockersjv, that’s if they’re seeing the same issue as you.

I’ve not seen others report it yet, as most recent posts seem concentrated on the fix to the audio quality issue that reduced Sub output for Arc, Beam, or Ray when paired with a Sub/Sub Mini whilst Trueplay was enabled, following the 14.12 update, but it’s still early days for the new 14.18 update, I guess.

At this point, it doesn't matter what sonos says or what independent test results indicate. Some folks lives have apparently been ruined beyond repair by this "14.12 killed my system” issue.

I think perhaps a few people might have been somewhat confused by some of the ‘terms’ mentioned here, but maybe this news media article and YT video will help to clarify things:

• https://www.theverge.com/2022/10/19/23413120/sonos-arc-sub-volume-trueplay-bugs-fixed
• https://youtu.be/r9noXA8qPNU

What I do know if that this update has wrecked the gen 2 sub. I have two play 5 Gen. 2s and a sub and the bass is way better with the sub turned off!. The sound is now terrible. It’s basically as if the sub has been disabled. 
Edit to add….FIXED!

 Problem resolved with a power cycle of all affected devices. System back to being great, possible sounds even better, but hard to be sure without side by side comparison. 

I’m trying my hardest to be patient and understanding, but the answer to your question is literally in the image of this post. You clearly didn’t even bother to look at/read the entire post before commenting. Stop wasting other peoples time because you’re too lazy to use your eyeballs.

the 5.1 issue is reduced output, Volume and bass, when paired with a sub and Trueplay enabled. Kinda been the main topic of conversation around here for over 2 months now…

What is the 5.1 issue???
