It’s the Amps that connect to the app. The passive speakers connected to the Amp have no connection to the app. Your statement that “the amps are not seeing the speakers” makes it unclear what is happening. Can you clarify?

Inside the amp when you Trueplay they send a tone to the speakers to confirm they are architectural speakers, then you can continue to Trueplay tune them. They are now giving an error in the app-

No Sonos Architectural speakers detected

If you have some in this room, make sure they're wired securely to Sonos Amp and try again.

thats why I said the amps aren’t seeing the speakers, the tuning happens in the app. 

Has something been ‘inserted’ between the Amp and the speakers on the wiring, like a volume control, or something?

I’d certainly try a power cycle of the Amp, if not, but if there is no break in the wiring, and the power cycle doesn’t help, I would call Sonos Support directly to discuss it.

Unfortunately the setup hasn’t changed in the 3 years I’ve had it. I’m wondering if it’s a software issue in the amps or even the new app. I have an Era 1 that I do Trueplay with on a different system. Granted I do the quick tune but it does it. 

The Amp can’t do a ‘quick tune’. There are no microphones in the Amp. Two different situations. And frankly, IMHO, Sonos marketing shouldn’t call those two processes by the same name. 

It’s probably best if you were to submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

I’ve sent them diagnostics and going to have a phone call with them when I get back home. Wanted to see if anyone else with the same setup was having the same issue. To be fair the initial steps they were having me do weren’t at all related to the issue so we will see what happens  

I’m afraid, not unlike any CS group, some have better experience/training/knowledge than others. I don’t normally recommend this, but I’d feel free to ask for someone else, or just end the call, then call back in. Fortunately, each time I’ve needed to call Sonos, I talked with someone ectremely knowledgeable, and helpful, but can easily expect that not everyone on the phones have that experience, and are reading from a script. 

Shoot, I’m careful not to respond to every thread on this forum…it must be more difficult for them, they don’t know why you’re calling in, until they talk to you. I get to pick and choose who I annoy ;)

Oh for sure  I’ve only had to reach out a few times and had great customer support. This last time was a little iffy and I ended up leaving the call but only after my home network crashed. More along the lines of others are seeing the same issue therefore I can lean towards software based than anything with my particular setup. I have 3 different amps and they all are exhibiting the same issue.

If all are exhibiting the same behavior, it certainly could be the firmware on the devices….but could also be something in your network. I’d call in again, and maybe see if you can get bumped to level 2 support…which will likely take longer, as a guess, but perhaps give you better knowledge at the end. But I’d start with whomever answers the call. 

Separately,  I posted a version of this problem on the thread earlier today. I too have been wondering if it is a bug that showed up in a recent upgrade. In my post, I asked if mixing the speaker wire polarity could cause this issue. Like you, that's has not been a problem for me until recently. 

Are the speakers emitting the tone?

They are not. Says an error in the app when you either try to Trueplay or just hit the button to look for the speakers. 

I’m thinking it has to be software based at this point. The fact it’s happening on 3 different amps with 3 different sets of speakers makes me lean that way. 

The saga continues. I was suppose to get in contact with layer 2 tech support but can’t seem to receive an email from Sonos to schedule that time. So for now, I will continue trying to reach out and get a hold of someone at tier 2. 

I am having the same issue. Waiting on level 2.

It’s unfortunate but good to see others with the same issue. I have not been able to get a hold of level 2. Not sure what to do at this point. 

They gave me a case number to follow up I will do so in the next couple of days. I suspect it’s an app issue. I even tried to create a Sonos net to eliminate any network issues but I could not get my app to forget the wireless network. 

Yeah to me it is a software issue. I’ve had the same setup for years and didn’t have issues before. Mine are all hardwired as well. If you get to level 2 keep us updated here! I’m suppose to get an email to schedule a level 2 call but I’ve never received one and it’s been multiple weeks with multiple calls to support. 

I have same issue, I will call the support tomorrow and see what they say 

I have the same issue.  Poor Sonos is a dumpster fire these days.  Not much really does work.

Goes even further than this.  If I am listening to music, there is no difference between ambient and full mode.  Sonos has pretty much rendered my surround Sonos speakers and Amp useless.  I have made my last Sonos purchase, not what it use to be.

Has anyone been able to get a hold of tier 2 support?

Any updates? Same issue. I have 4 rooms with Sonos architectural- 1 outside speakers ,1 ceiling, and 2 in wall. Only 1 of the 4 (in wall) will still do true play. No other changes- smells an awful lot like a Sonos app issue

It’s def seeming like an app/software issue. I do finally have a call with level 2 in about 30 mins. Will come back with outcome. 

Well quick update, had a time scheduled today and never received a call. Now back to square one again.
