Line-in sound cuts out all the time

I connected one of my Sonos Play5's to my computer via the line-in headphone jack. I have 2 other Play5's and a bridge. Those other 2 Play5's not connected to the headphone jack very rarely produce sound consistently. This is a really bad problem for me considering that I play all sporting events and video thru my computer. I'll have guests over to watch a game, and 2 of my relatively expensive Sonos speakers constantly flicker in and out so bad that I just have to turn them off and hardwire other speakers. What I've tried: rotating the speakers, disconnecting/reconnecting, removing all components and re-adding all components in the Sonos program. The router is not near any of my Sonos components. I'm not running other programs that take bandwidth, and if I'm streaming something online, the video will continue to work while the sound cuts out. I have a 110mbps connection. Thanks for the help. -Kevin

Brilliant - many thanks for that. All now ok. Thank you.
On your controller device, open up the Sonos app. Then (usually), click on the three dots at the bottom right, which should say "...more".

Then click on Settings.

Then click on Room Settings

Then click on the room name that you have your line in on.

Then click on Advanced Audio

Then click on Line In.

This will take you to the place that you can change the Source name, the Source Level, and the Autoplay room (the room the line-in source will automatically play in when you start it

Now back up to the "starting" page, and click on Advanced Settings

This is the page where you can change the SonosNet channel you're using. If your using wifi, rather than Sonosnet, you'll need to change the channel that your wifi is using on your router. Since each router is different, you'll need to look that data up in the manual for your particular brand and make of router. You can usually find them online, if you don't have a paper copy.
Hi, I'm having trouble with Line In dropping out repeatedly. Can't understand the options given so far. For example where is 'under Sonus, go to Presferances etc' I can't find any of this. How do you change router channels, is another one. Please explain for the none techy.
Thout I would try digital/coaxial line into... OOPS! Only analog, duh... Connects output digital but Amps only line-level analog in. LAME!

Looking to see what’s up with mine too!

I was having the same problem with speakers cutting out when playing my turntable connected via line-in. Yes, setting to "compressed" worked, but who wants that when dealing with vinyl?
A solution found mentioned on here somewhere (can't find it to thank the guy) is to switch the line-in device name to "Airplay device". That apparently gives a second more of buffering time (as Sonos thinks its dealing with an airplay device) and since switching I haven't had one drop.

What is odd is that the Amp getting the Tivo singnal (physically wired) does not do so but any grouped Amps down the line cut out.

Set to compressed & cut-out gone but now a 2-3 sec delay from my Tivo in 7.1 fam rm (hdmi) to Connect Amps grouped or not w/a analog line in to any of 8 zones/Amps in my rack. All devices are hardwired except Playbar 5.1 setup in my mbedrm but not related. What to try next? Digital from Tivo into an Amp? How can I tell if all worked Sonos devices are using hardwired cat6 only? No wifi, sonos net, etc.

This worked well for me too! I wish Sonos had an official feature for this rather than using the Airplay device mode as a workaround.

Another note for those who don’t know: if one of your Sonos speakers is near your WiFi router or somewhere you can easily run an Ethernet cable, doing so will change your Sonos setup to BOOST mode (same as if you bought a separate BOOST device) which means Sonos is creating its own wireless network. This is another method that worked for me to create a stronger signal and prevent signal skipping.

Thank you for posting this! I had multiple brand new vinyl cutting out all the time and it was driving me INSANE. I came on here looking for help and this seems to have done trick (and also increased the volume at which the vinyl plays too). I did also switch from Channel 6 to 11 (after 1 had cut outs too), so perhaps it was a combination of the two things. Anyway, back to enjoying music again, finally.

Everyone, if intermittent drop-outs are the issue, and changing the channel on SONOSnet or changing the Wi-Fi router channel doesn’t help... and if compression is not an option (due to either sound quality loss or audio/video sync latency), then I would suggest considering getting possibly either a SONOS Boost (rather than just a bridge or home wi-if), or using a wired Ethernet connection to get around the wireless interference issue. In some home constructions, that might be the only practical way. Or getting a Wireline solution, which can turn your power socket into a wired network connection to get a greater range where Wi-Fi isn’t an option (poor signal), and installing Ethernet (possible rental, or solid walls) also isn’t an option.
HOW DO YOU DO THIS?

yeah Sonos is pretty garbage TBH, if you are serious about getting good sound. NOBODY who is trying to listen to vinyl wants to stream a compressed signal!!!! I dont care what the hell the compression setting is. I just bought a boost because some support moron said it would certainly be able to stream uncompressed with no drops, but it is still dropping just as bad. I want to sell all this sonos garbage. AWFUL product
I'm getting cut outs on the play 5/connect combination, as well. Can you take a peek at my diagnostic? My confirmation number is: 7618574.

Hi Angrybear,

We hear you and would like to find a solution for you to get this Line-In working more reliably. I understand that you have been told to call in by a technician before t call in. We have multiple levels of Support, so if our Tier 1 technician is unable to get the line-in to work, our Tier 2 will continue working with you until we do.

If you have the ticket number with us, I'd be happy to take a look at that and see if there are any other immediate changes that will need to be made.
I am having the same issue. When I play music from the app all 3 of my units play great (1 play 5 and 2 play 3's). When I play audio to the line in it cuts in and out so bad that you can't even use it. I've tried every possible setting. I even went from using an aux cord to an optical cable from my TV. No luck. I've tried compressed/uncompressed, every channel possible. It's pretty frustrating. I've submitted 2 different diagnostics and haven't received any help. I just receive "call us to troubleshoot". Which I know they are just going to have me try all of the things I've already read and tried. Seems to be a very common issue. odd to think that they haven't found a bug fix or admitted that the line in and sending audio to grouped systems doesn't work well.

Same problem I'm afraid (with a Mac line-in). Have tried compression. Diagnostic: 7072997.

Hi fecklessstudent,

It looks like your PLAY:5 is connecting to your wireless network but that it is losing connection from time to time. Also, there's an ethernet cable connected to the PLAY:5. We don't recommend using the ethernet port when your speakers are connecting to the wireless network.

There are some other wireless networks in range on the same channel as yours. This could be the reason your speaker is losing connection occasionally. Please try changing your router's wireless channel to 1 and see if things improve.

It may also help to head into the Sonos app's settings menu, then choose advanced settings and set the compress level to compressed.

HI I am also havinbg issue with the line 1 cutting in and out...
Here is my diagnostic number; 7069403

Any help would be greatly appreciated.


Hi SankeysRTW,

There's quite a bit of wireless interference showing up which is likely the cause of your playback issues. Please start by changing the wireless channel your Sonos system is using. It may also help to set the audio compression to compressed in the Sonos app's settings menu under advanced settings.

I'm having the same issue. Can you check my diagnostics? 6980171

Hi Keenant,

It may help to set your audio compression rate to compressed. To do so, head into the settings menu of the Sonos app and choose advanced settings. Uncompressed audio can use a quite high level of bandwidth, which can lead to audio interruptions when streaming to other players.

You may also be able to improve the connection between your speakers by changing the wireless channel your Sonos system is using. There's a bit of interference showing up which can limit the effective bandwidth.

I just hooked up a turntable and am having the same option. Changing to compressed worked but I hate that I'm having to compress my music. Is there any kinda work around to get the full experience?
