Connect - LINE-OUT low volume since update S1 app

Hi

 

I have been a Sonos user for many years and had my existing core system in place for 9 years.  

 

Part of this system is a Connect that I use the line-out from to feed into another system.  This has always worked fine, but since the recent S1 app update, the volume of the line-out has dropped to virtually nothing.

 

It has always been set to “Fixed” and operated perfectly.

Now in the second system even with the volume in the second system set to max it is barely audible.    The only change is the App.

Ive connect a second device to the Line-OUT and this too has very low volume, so its not the secondary equipment.

 

I have to say over the years I have become more and more frustrated with the Sonos updates and the delays in the various fixes that these usually cause.  You have pushed me into the S1 sub culture now - how long is this going to resolve ?

 

The Sonos products consist of this connect, 4 connect:amps, a Play:1 and a ONE.

The external device is an old Living Control (that to be honest has been much more stable than the Sonos) and a blackstar mini amp that I performed the second test on.

 

The connect has the following details:-

Sonos OS: S1
Version: 11.2.3 (build 57381090)
Hardware Version: 1.16.5.5-2.0
Series ID: P100

 

My PC controller is v11.2.3, S1 OS, Build 57381090
my App is v 11.2.3   Build 57381090

As a follow-up to my post from a few days ago, I was able to try an optical cable, and that output signal works perfectly as reported by others on this thread. Since that is sufficient in my application, I am giving up trying to understand the RCA low line levels output problem.

I talked to a support tech once who made me go through another factory reset (after sending diagnostics and having some kind of live monitoring) and also had me connect a passive speaker to the line out RCA. It was far too weak to make any sound at all without an amplifier. With an amp I could only hear anything very faintly if the amp was jacked up to full volume. Anyway, I wasn’t getting anywhere, so I gave up and went the optical cable route since the only other option appeared to be getting a replacement device. The person I spoke to also did not seem to know that others have had the same thing happen.

One other note - I also did the test where I used a pair of RCA cables to loop back from the output to the input, then play music on the faulty device, and then use the faulty device’s line in from another working device. Same behavior except now the faint sound was coming from the working device turned right up.

The fact that so many people have had what seems to be the exact same issue leads me to suspect a software bug, so perhaps a future update will eliminate this fault.

Just as a datapoint, I’m not seeing this issue on any of my 3 Connects, using their analog outputs and running S1 v11.2.9 firmware.

Sound like this might be a hardware issue with the line level output stage?

    I count six occurrences in this thread to date and there are others if you google. It might be a common hardware failure, but... Reports indicate that it has affected both ZP80s and 90s. Also, there was the post earlier in this thread that indicated someone had trouble with 2 of 5 connects after an update. 

    I also have three other connects that don't have a problem on 11.2.6 (build 57587010)

    Ditto with two Connects. This isn't a software issue.

    I disagree. Just because most upgraded Connects still work fine post upgrade that is not particularly compelling evidence there is not a subtle bug that affects a small percentage, especially given this thread is evidence of a cluster of devices (manufactured a different times) in recent months with the exact same failing condition. At this point, I believe it at least as likely to be a software rather than a hardware issue.  That is until someone takes a couple of fault units to pieces and traces the signal loss to a common failing component.

      I am having this exact same problem with my connect. It has actually happened twice now, I just updated today and it got worse. On my amp I have to set volume at 70 to have roughly the same output as I previously got at 60, and prior to a previous update it was 50.

      What’s the ‘source level’ set to in the Connect’s room settings?

      I don’t have any Line In attached, so no source level. In faint grey text it does refer to Airplay and Level 4, but Line In is “Disconnected”. Line Out is set to Fixed.

        To be clear, I am referring to a non-Sonos amp connected to the line out of my Connect via RCA. I have had the volume drop occur two times now, both times after an update.

          Ah thanks, I (mistakenly) assumed you were referring to playing a line-in source on the Connect. Sorry about that.🙏
