In my app I sometimes see line-in and sometimes I don’t, suggesting line-in functionality has been added to the new app but is buggy. This probably explains why its not on the list you referred to, as that list was about features which have not yet been added rather than bugs.

Nope, that is not the issue.  You can only fully quit an app so many times and restart it and the Line-In never shows up.  Will wait and see if any SONOS authorized rep answers this.

I mean, I have it and it works. So its not something missing from the app in the same vein as the items in the list that you referred to. If you never see it then it can only be explain by a bug or something local to your system. 

Have you actually plugged something into it? When I said earlier that I sometimes see it and sometimes don’t, I have a suspicion it might hide itself / disappear when nothing is connected/active. I just connected something and it immediately appeared.

Upon reviewing further, we found that using the GOLD app it senses if a SONOS device supports Line-In or not regardless of anything being attache to it. The BLACK app does not.  Since we have clients that use multiple input devices (CD player, MP3 editor/player, 32 track mixing boards etc.) they don’t always have something “plugged into” the device.  In this case we are testing with the Port.

Further, as it turns out, in order to have the “Line-In” visible, at a minimum you must have BOTH RCA inputs plugged in.  Then the “Line-In” appears.  NOTE: there does NOT have to be any device plugged into the other end in order to have the Line-In appear.

But that is now a secondary issue, as on my iMac computer where the library exists under the SONOS Mac application, SONOS forced an update by rendering the existing, operational version of the S1 Mac app.  Once the new “S2” version was downloaded and installed, it will no longer allow the addition of the Music Library that is hosted on the iMac and synced with the local iTunes Library.  It gives the error 913 that is shown on the attached image AND FROM REVIEWING FURTHER, THIS ISSUE IS BEING REPORTED EXTENSIVELY ON BOTH WINDOWS AND MAC OS COMPUTERS, STARTING YESTERDAY, MAY 14, 2024.  Personal information deliberately redacted.

Same, Android...app updated, i can’t find a line-in option.  This didn’t happen until i rebooted the phone and got the new version.

Also most of the time, it will complain about “No Sonos System” until it realizes its wrong a few seconds later, and as a software engineer, i don’t think you can ignore something about that coincidence.

Wow! This will be the straw that broke the camels back for me. I have my new Mcintosh pre/amp system porting through two outputs (main stereo and Whole home on second output to my connect. Now I cant output line in Vinyl audio to the rest of the house?

Yup this is missing from the android app on my phone.  I can no longer listen to records at all.  This is a deal breaker for me as the ability to connect my record player was the main test for whether to purchase Sonos speakers.  Without this I'll have to sell these and get something else.  This is absolutely ridiculous.  I'm a business major and a software dev and this app change would have flunked someome out of business class, not to mention that I've never worked on a design team that would have approved removing such a main function.  Terrible business decision, Sonos.

I feel like I've been bait and switched and don't think I can trust Sonos or their products again.

I agree, Sonos had proved to be disappointing in the extreme.  The old app was great, helpful and straightforward but sine the change of app I carnot get the line in to play, so no CDs and the whole point of buying Sonos wasted.  A dreadful experience all round.  I just want to play a CD!!

I didn’t see adding this back in the letter from the ceo. Did anyone?

Just a letter of nonsense, hardly committed to a speedy resolution.  Appalling service.  What a mistake to purchase Sonos.

So .. is there a workaround? Or we just SOL until a fix goes through? Very disappointing 

Just adding that I also have the same problem on Android. After the new app was released, line in was available at the bottom of the home screen. Sometime in the last couple of weeks it has disappeared. 

Yeah same, line-in appears after resetting the app, or the port, or just some fiddling. It's very unreliable and buggy. 

Weird to me that it just doesn't work well. Especially since the Port is there to do exactly that...

I came to find a solution to the same problem. Since the latest app (BLACK) I've lost my Line In which is a big problem. This is a required feature for physical media. 

When will it return?? 

I have no solution, I hope Sonos reps reply to this thread with answers.

When it next appears move my sources to the top of your home screen.  That worked for em and it is now always there,  I have a turntable attached to an ERA300.

Do you mean when the Line-In appears? I don't see it at all, and haven't been able to get it by resetting the app etc as suggested

So I have a Port and it appears sometimes when I reset that, or unplug and replug it. 

What do you have to reboot to make it work? Last week I couldn’t see it and updated my app. It appeared. This week, it has disappeared again and yet in my Connect options it suggests that it is Connected, but can’t find anywhere to select it and it seems heavily locked to Spotify.

I am having the same problem.

As a workaround to play my vinyl records until Sonos can fix this dumpster fire of an app experience, I found the Autoplay config to be helpful. Since I usually listen to vinyl records in my office, I set up Autoplay and at least I can now listen to my records even though the line in output does not appear on the home screen. Hopefully this helps some of you!

The two line-in sources I use, has always shown on my Home Screen of the Sonos App under the “Your Sources’ area.

I see it just below the locally shared Music Library and it’s there on both iOS and Android controller Apps. See attached.

If I select the arrow on the right of the line-in in the App, I see this (attached):

Mine was just missing on my android phone but was present on my iPad. So, I tried reinstalling the app on my android device and that seems to have brought it back. 

I've reinstalled the app multiple times and sometimes it decides to work, other times not. Looking forward to a patch
