No Sonos Architectural Speakers Detected

I have 4 Sonos amps and 4 pairs of Sonance by Sonos speakers.  2 pairs are older and are detectable by the amps and 2 new pairs are not.  The 2 pairs that are not detectable are brand new out of the box.  The amps are from Sonos and the speakers were from Amazon so there is no question about authenticity.  Why aren’t the speakers detectable?   I haven’t been able to find an answer here.

The speakers work to play music but they are not detectable with the true play feature like my other 2 sets are.  I have another set not installed here and don’t see any switch / dongle on them anywhere?  

You should contact support as there has been a recent bug that caused this. you can find threads here on this such as;

​@Huskie32 

As far as I know the Sonance for Sonos speakers are equipped with some kind of „dongle“ to be ready for trueplay. Is it this what you mean by saying „not detected“?

Or are you failing to use the speakers at all when being wired to the amp?

Anyway I would contact Sonos support to run diagnostics and check this.

I don’t know how that dongle recognition technically is done in detail. I just heard there is some hardware (maybe tiny and build in just as an electronic chip) to make the speaker trueplay ready. 
So my recommendation really is to contact Sonos support. I suppose they can check this ny doing some diagnostics.

But as you can read there the bug has been fixed. So first step should be to check your app and firmware for the latest updates.

As you didn’t specify the speakers you own..do they meet the parameters below? Excerpt taken from this page at Sonos.com.

Good point ​@AjTrek1 👍🏻

We forgot to ask op if one pair of the speakers might be an outdoor set. 🙈

The speakers are in ceiling Sonos by sonnance bought off Amazon.  The amps bought from Sonos website.

Not all Sonance in ceiling speakers are the same. Sonos only recognizes some, I think they’re called Architectural speakers. Is this what you ordered from Amazon?
