Sonos is forcing people to buy new hardware as they've broken the Connect:Amp and they refuse to fix it

Hi,

 

I'm recreating this thread, as the discussion wasn't finished, but it was locked. I also wanted to make it obvious this is a Sonos issue, not a client environment issue.

 

https://en.community.sonos.com/components-and-architectural-228999/connect-amp-keeps-dropping-out-audio-6885634/index2.html

 

I've been following this for a while because I've been having the same issues, and when I spoke to support they said the connect amp can't cope with modern software and that I should upgrade to the amp, which is clearly unacceptable.

 

This has been confirmed by people in that original thread who have been told the same thing.

“FWIW, these issues seem to have occured after the June 2023 software update to S2 version 15.5. Interestingly, there is an alert posted in the release notes of the 15.6 update released July 25, 2023 about adjusting how older Sonos products use their internal memory. See below (copied from https://support.sonos.com/en-ca/article/release-notes-for-sonos-s2):  Alerts:      With this update, we’ve adjusted how some of our older Sonos products are using their internal memory. Because of this change, updates for Play:1, Play:3, Boost, Connect, Connect:Amp, and Sub (Gen 1 and 2) will take longer to complete than before. The reset process for these products will also take more time to complete after this update.”

“We continue to have intermittent drop-outs on all 4 of our Connect:Amp devices, so here’s my update after 1.5 hours on the phone with Sonos today. They said the diagnostics for one of the Connect:Amp devices the chose to investigate showed multiple major alerts, including:      Cannot allocate memory to full status     Write failed     Player crashed: out of memory     OOM Killer  These items all sound like they are related to memory issues with the older Connect:Amp product, as Big Bull mentioned in his previous post.”

 

Big Bull:

“Ok latest is I powered down 3 of my 4 units and just had the one I use most running hard wired to the router through my switch and it still gave dropouts so I sent 2 diagnostics to Sonos and they said : 

------------------ 

Thanks, so on this one in specific I can see the audio interruptions are caused because the product basically is old, and it is reaching its capabilities, there are some things that can be done to try to reduce the impact of this, but if it continues this product will need to be replaced with the upgrade program. 

------------------- 

I am being advised to replace any affected units with the Sonos Amp which can be costly.”

“  Same problem, 4 AMP of which two lose sound...  SONOS did a wrong analysis and accidentally said that there were memory failures in some of the units. But since they only give a 2-year warranty, mine was 2.5 years too old. How can SONOS sell products that obviously have manufacturing problems and then say that they can replace them with a 30% discount on new ones? Wonder if Tesla would sell cars that stop working after 2 years and say, sorry you have to buy a new car every two years because the warranty has expired. So bad from SONOS so I will be discontinuing my SONOS system and switching to BOSE...  “

 

For context, in my situation I have a connect amp, connected via ethernet with WiFi off, and I started to get regular drop outs around June. It's incredibly annoying, the audio will drop out for a few seconds before continuing, if other speakers are grouped they will carry on fine.

 

It's absolutely 100% not a network issue. When I was debugging it, I briefly made the connect amp the only wired device and turned on WiFi, and other speakers in my house worked perfectly at all times. I've also reserved IP addresses, and I ran a ping monitor on it to check for any network dropouts. There were none. I've put the system back now, so the connect amp has its WiFi off.

 

So it seems to me that Sonos have released a firmware update that the connect amp cannot handle, and rather than take responsibility for it, they're just fobbing people off telling them to buy expensive new hardware to solve the problem, not even with any substantial discount. It's unacceptable. This connect amp worked perfectly before June.

 

Sonos needs to release a new update that solves the issue, or give people affected substantial discounts on replacement amps, and formally announce that the connect amp is end of life. Currently people with issues on this forum are being unintentionally gaslighted by well meaning people who don't know that this issue exists. Sonos cannot say the connect amp is supported when they've released a broken update.

 

People need to know about this issue, I've seen loads of topics about this issue and people get fobbed off with network issues, which is absolutely not the case, at all. Big Bull proved this by doing a replacement to amps which solved his issue.

Hi @britcowboy 

Thanks for bringing this back to my attention.

We now consider this issue to be largely resolved, and any remaining cases are being dealt with on an individual basis. If you still encounter the issue described here, I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports.

I hope this helps.

Is not this present issue with Connect Amp memory cards there even where the Connect Amps are hardwired back to the core network? Why are channels relevant if that is the case?

If I am not mistaken even while hardwired SONOS devices still broadcast the SONOSnet backbone Wi-Fi.

They do if their radio is not turned off as it can be via the app. But comms between wired units are always by wire regardless of state of the radio.

Add my name to the list of Connect:Amps that drop out. Started a couple of months ago. Worked fine until then.

Adding myself to this list of users with issues on the new firmware.  I use Roon to send music to Sonos players throughout my house and am having issues similar to everyone here.  Roon loses connection with each of the Sonos players after 29 seconds.

Using Wireshark I was able to confirm the issue with my Play 3. From the Sonos Play 3 to Windows, I am getting [TCP ZeroWindow] and [TCP Window Update] and from the Sever to the Device I am getting [TCP Window Full], to which the device then drops off the connection.  It seems when Roon sends the song data it is too much for the allocated buffer of the device.

This firmware bug is impacting Play1, 3, 5, Connect and Connect Amps that were originally on S1 and upgraded to S2.

Using Plex, Sonos library I can get more playtime out of it, but it will eventually cutout.  Similar to some of the old Play 1’s will work if I reduce quality to 16 bit on Roon, I can get them to play a bit longer.  But the Play 3, even a 96kbps AAC file through Roon it will cut out at 29 seconds saying that the allocated data through TCP is full and the device closes the connection and stops playback.

Interesting, hopefully that information will be forwarded to the development team to aid them in finding a solution.

Sorry to hear that 16.1 isn’t working. 
The S1 rollback remains utterly stable (devices and app) after more than 10 weeks of continuous up-time.

Yup still an issue.   Like others rolling back is not an issue due to mix with other newer kit.  (Relying on nightly power downs on a smart power strip.)

Is there a procedure to roll back the entire system of connects & connect amps to S1?  If that fixes it, that would work for me.

Yes. You’ll find the procedure on the Sonos website. 
Be patient - sometimes the devices will hang on the roll-back and you have to wait and if that doesn’t work, restart the process for that particular device. 
 

I’m nearly 11 weeks into the rollback and even the latest S1 app is stable.
