app updates have duplicated music library albums and lost some tracks

I have the same problem v16.3.1. It used to work as expected before this recent update. The controller software has now been made even worse by this latest bug.

I have the same problem, multiple copies of the same album, up to 10 or 12 copies, and when you click on them to see the contents they are all in the same jumbled order, maybe track 8, track 6, track 1 etc. However, the whole album is there. It appears that the problem is with compilations predominantly but not all the compilations.

It also means that not all of the albums show under a particular artist. So I have about 30 or so cafe del mar albums and only about 10 of them show on the iOS app. However, if you go to the Mac os version then they all show but still got the multiple copies.

When I have checked my NAS drive, they all appear normally, no multiple copies and if I stream on my Uniti Atom, they appear in the Naim app exactly how they appear on the NAS drive.

Pre 16.3, even with all the app problems, this did not happen. it is only since the upgrade that I have experienced this. Hope there is a fix soon as this is very frustrating.

It’s not like you can put the mis-indexed songs into something like, I don’t know… a queue… where perhaps you could put them in the order you want… now there’s a radical idea… 😜

Yes, you are absolutely right. The issue is entirely driven by the SONOS app.   My library too is exported from itunes to my synology nas and also copied onto other devices via Isyncr. I link to SONOS via the y Synology.  SONOS destroyed my ability to play from my local library, partly repaired it (without album artwork) and have now screwed it up again.. I despair. 

I used to love my Sonos speakers and constantly on the lookout for something new to add to my ever increasing collection of speakers, but all the issues this year have made me totally lose interest because I realize how quickly they can destroy the thousands of dollars I invested in the blink of an eye.

Similar problem that affects (so far) only latest addition to my Sonos library: A new double album I just bought in iTunes (on Windows 11) displays as 12 albums in my Sonos S2 controller, each one with the 14 tracks listed in the same scrambled order. My Android Sonos controller shows the album exactly the same way - duplicated and with the tracks scrambled.

All metadata is in order as far as I can tell; tracks show disc # and track # since it’s a 2-CD set.

My PC file system shows the album as a single folder. It appears as a single album in iTunes and in my MediaMonkey 5 music player.

My Sonos Windows controller is up to date: Sonos S2 version 16.3, build 80155014.

The Sonos support bot mentioned that “a Sonos music library has a 65,000 track limit.” My library has 8357 files (tracks) according to the MediaMonkey library listing.

I bought and downloaded another album today, partly to test whether the problem I reported yesterday was a one-off. It was not.

The new album shows in my Sonos library in two identical copies, identically scrambled:  track numbers run 1-6-2-3-4-5, no problem for me since tracks 1 and 6 are standalone pieces while 2-5 are a set.

Sonos happens to list today’s tracks in alphabetical order but yesterday’s album tracks are not, so that doesn’t seem to be what’s happening.

I have to assume that the most recent Sonos update is causing this problem as it’s never happened before in years of adding albums to Sonos.

 If the Artist tag & Album Artist tag are not exactly the same 16.3 screws it up.  I normally tag compilations with the performer for the Artist tag & Various for the Album Artist tag.  So my compilations are a mess.  Hopefully Sonos will fix this soon.

 I learned long ago to match Artist & Album Artist tags ( with the exception of compilations ).  Makes it easier to find the artist you want.  This is very important for classical albums where the default tags are all over the map.

I also have the problem. This is 100% a Sonos issue. I have the same library connected to my S1 system and it’s fine. No dupes, no missing tracks. The same library that I have been using and adding to since 2006. 
 

Last man / woman out please switch off the lights. 

I have same issue, using 16.4 beta windows 11 and android app. so no fix as of yet
