No, haha! Using the word "cut" was simply to elaborate the point that the only change to the previous setup was injecting a CONNECT device into the middle of what used to be a continuous connection. I am now using the cables provided with the CONNECT (3.5mm to RCA and RCA to RCA) to make the connection path.

Being Mother's Day weekend, I am going out of town and will not be able to test the device immediately but I will plan to give the device another endurance test Monday and post diagnostics then. Thanks you for continuing to look into this issue.
The audio has been dropping out from my system and is getting worse. I have 4 x play 5s and a Sub played via a Boost set up which is hard wired into an Apple Express (wired extension of my router). I am running 70-80 mbps now and was running on 6 Mbps but the dropping out is worse since the broadband speed has improved! I thought that would fix the issue as I thought it was due to buffering. It has been dropping out on Sky too. I use my set up to watch TV with the TV headphone socket wired a Sonos speaker (Line in). The sound dropping does not seem to be an issue with listening to music from the phone or streaming but just via the TV. I have had issues of latent sound ie not in time with the video/lips moving.

I have sent a diagnostic - 7419496. I hope this helps.

The Sonos boost, Apple Express, Apple TV are by the TV and 2x front Play 5s. From reading some posts I fear it may be interference. I don't know how to change the fibre settings but I am Level 2 AV on line in source and channel 11 Sonos net channel (should this be channel 6?). I appreciate any help or suggestions to rectify this matter and improve the sound.

Best regards

hey kdr2566, welcome to the community. What you're doing there is something the speakers were not really designed to do. You've got a first-gen PLAY:5 trying to broadcast a completely uncompressed analog audio stream to four other players over wireless. This is pushing the limits of what that player can do, and what 2.4GHz technology is capable of. This is why our home theater setups all use 5GHz to communicate. We can try to clear up some of the interference you have there, but to be honest it's not far off perfect already and any improvement will be incremental. You could enable some audio compression in the advanced settings of the app, but this will add more lip sync delay. If your TV has any settings which might allow you to compensate for this, then that will be the easiest fix. Otherwise, you might have to connect them all up with Ethernet cable which will be a basically perfect connection.
Thanks Tom. I changed the to channel 6 from 11 which seemed to help or is that not connected to this issue?
I appreciate this is not an ideal set up but I guess it is good to hear that the wifi interference is minimal. I could connect the two front speakers by Ethernet to the switch box but not the sub and rears because they are too far away.
I was chatting to Emily in the sales chat re the sound bar, which I thought may complete the system, but my Sony TV is 6 years old with no optical output. Can I connect the sound bar any other way? Thanks again
Thanks Tom. Appreciate the help.
@dakotalazenby - Welcome to the Community! Sorry you're having trouble with the CONNECT. It sounds like submitting a diagnostic report would be great, especially while we are passing PS4 audio through the TV.

I'd also check the audio from the headphone jack on the back of the TV while passing PS4 audio through the TV as well. We want to check the full signal flow at every possible break point.

Thanks in advance.


After a month and a half of being out of the country, I finally had the time to sit and watch a movie today. The problem I was experiencing before I left it seems I am still having. The Connect will sporadically cut out all sound. Please see the topology diagram and descriptions from previous messages for details.

I have Line in turned up to 10 as suggested in other people's comments.

I also submitted diagnostic: 7666701

I submitted it today during the movie. It seemed that the sound most frequently cut out after the movie was loud for a bit and then after reaching a quiet part the sound would die. Sometimes it would recover on its own, sometimes you had to go to the app and hit play on line in. Could it be something with the Connect device measuring input amplitude to determine whether it is playing or not and cutting off due to low amplitude input?
For what it's worth, I had the same issue for the longest. And my home wifi is solid. I decided to try installing the Sonos Boost just to give it a whirl and it's solved nearly all my issues. I still experience it once in a long while but for the most part it's eliminated the issue for me. It would occur daily for me before.

Hi

I experience this problem also for a long time. I read the whole thread and it looks to me that for some it was a problem with wifi. But for some others it ONLY happens when using Line-IN. And some it did work a few months/years ago without any problem.

I tried all the difference solutions mentioned here and it Line-IN still doesn't work properly for me. I have everything wireless and did tests with all sonos wired. But it doesn't work here. So I expect for me it is not a wireless problem.

I find these answers interesting where sonos obviously mentioned this: "The info I got from Sonos support is that after V7 and Spotify connect, the system uses more CPU-power. "

The strange thing I have is that it sometimes does work really well and then it changes within minutes to really bad.

My Diagnostics number is: 7720133

Thank you for your help.

Just looking for an update from Sonos on this. It is really annoying that the sound cuts out randomly and for varying amounts of time during movies and games. It is doubly annoying that I was out of the country for the majority of my "return period" and now I am stuck with a seemingly defective device... unless it is something with their automatic input amplitude monitoring algorithms that turn the device on automatically when it detects sound on line in, I don't know WHY it would intermittently STOP patching sound through from line in to line out...
Well, here's another diagnostic... just in case the old one I posted has expired by now. Same issue, same device, now well outside my return period.

It's a good thing the other speakers work so well, because this Sonos connect issue is really getting under my skin.

dakotalazenby: Thank you so much for your patience, while we get caught up here in the Community. I was able to take a look at the diagnostic from the 30th of September, and you may be hitting on something about the signal the CONNECT is receiving. Based on the diagnostic sent, I can see that the CONNECT is detecting the sound to be WAV, shortly after it detects silence and will auto-stop. This lines up with you are experiencing. If you try plugging in a different audio source (such as your mobile phone or CD player) to the CONNECT, do the issues persist? We essentially want to nail down what side of the CONNECT is having the problem.
Hi, unfortunately same problem here.

I use Connect with line-in and stream it to Play:1 (same room). Sound randomly drops out on both devices. Sometimes together, sometimes only Play:1. Tried different audio cables, sources, setting Line-in source level to 10 with no luck.

Even worse is the second scenario. Streaming sound from TV using Playbar to Play:1 and Connect. Same behaviour - sound drops out every 10-20 seconds.

I have also Play:5-2 and it's behaviour is same and it doesn't matter if it's in the same or next room.

I have to say that using Spotify or playing file from NAS works great on all devices. No lag, perfectly synced without any error. But Line-in in Play:5-2, Connect and Playbar (counting optical cable like line-in) doesn't work 😞 So bad, just bought it 2 weeks ago :@

I have submitted diagnostic (TV streams to all devices): #7974035
Thx

Apther: Thanks for reaching out and for the diagnostic. I was able to take a closer look and noticed that your system has a few things we may want to take a look at. For instance, the PLAYBAR is dropping about 25-33% of the data it should be transmitting to the router. This can be due a few things like the wireless environment or what is physically between the two endpoints. Not to mention a few DNS errors, it may be best if you are able to give us a call and have a technician look at this with you over the phone in real time. We can set up a remote session to get some eyes on your local network and see what is going on. Our contact information can be found here.
Keith N,

Thanks for looking into the problem. After being away from home for a while again, I finally managed to have enough time to run the test you requested, plugging up another devive into the CONNECT. Two things:
(1) I have tried a new TV (Sony Bravia 900 4K) and it suffers the same problem. The CONNECT occasionally (5-20minute cycle) drops the sound.
(2) I tried unplugging the headphone plug from the TV and plugging it into my phone. The rest of the setup remained unchanged except the source. The system ran fine like this through 1.5 full albums played through my phone using the iPhone music app. The iPhone was sending the music into the CONNECT and the CONNECT was able to stream the music to every other Sonos device in the house without dropping the sound.

The afterword: Immediately after I played over 1 hour of music on the CONNECT using my phone, I switched the headphone plug back to the Sony Bravia and within minutes the sound cut out. So I generated a Diagnostic.

The Diagnostic is: 8199617

Since that Diagnostic (30-45 minutes ago) the sound has come and gone 4-5 more times. It seems like when the sound cuts out, you can go to the Sonos controller on the iPhone and press play and most of the time the sound will come back, but even then sometimes the controller app doesn’t always bring the sound back. Sometimes, if you leave it long enough, it will recover on its own without using the app. During the last 30-45 minutes it has recovered with no intervention once, and it has been started up using the app the remainder of the instances.
I have the same issue

1 play 5 2 gen. Connected to the tv via Line-in.

My dignostic nr is 6995841



I've the same problem since I've a stereo paire....work perfectly with music...don't work with line in / Tv

Help me please! Thx

Same here.
Streaming move sound from Apple TV via airplay on airport express which is plugged in line-in input on connect apm.
Sound disappears when I am switching between applications on apple tv and some time while I am watching movie.
Diagnostic report # 8390369
And here one more diagnostic report where sound breaks in the middle of the streaming: 8390436
Any one have update on this issue, I am Experiencing same problem, with 2 stereo Play 3 and a connect line in to the TV Samsung UE48JU6400
I tried Line 10, Channel 1 6 10, ethernet...

Same issue.
I'd recommend that you submit a system diagnostic within 10 minutes of replicating this issue, and contact Sonos to discuss it. There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.
