Sonos 14.18 Software Update - 5.1 Issue Still Present

as expected...

Interesting that there are many people in the main thread that claim that they’re quite pleased with the new release. 

I trust their ears more than I trust a low level CS rep, who probably doesn’t own a Sonos. 

But it’s entirely possible that this is merely a step in the right direction, and not a full “it’s finished” release, which may be why they don’t call it out as a ‘it’s finished” in the release notes. 

Hope I'll find the same when I'm back home in November 😊

What is this 5.1 issue?

I am in the "14.12 and everything since is fine” camp. 14.18 seems to have addressed the volume (non)issue to some degree, i.e., more loud at a given volume setting (subjectively to my ears). 

14.18 has improved my system no end, bass on Arc superb and greater definition on play 1' as surrounds

The fact that it didn’t prompt me to re-tune TruePlay reiterates what OP said. I’ve gotten used to the ‘raw’ power of the system having TruePlay off but it would be nice to get a solution so I can get the best config based on my room. Here’s hoping for 14.20.

Maybe Peter Pee has some more answers on what this update addresses.

What is the 5.1 issue???

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 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.
