Missing Album Tracks after track 9?

I  have recently noticed that my sonos media library has dropped tracks from albums after track 09 ?

The album tracks are in the folders on the NAS

I checked the tags using MP3tag, 

My NAS media server software recognizes and plays all the tracks on the album and they appear in the Album & artist views correctly.

 

However, The Sonos shows that whilst all the tracks are in the folder view only the first 9 tracks appear in the Sonos Album or Artist views, the rest of the tracks are missing and they are also missing from Search.

 

I deleted the Sonos Media Library and re-added it with the same result

 

Anyone else noticed that they are missing the tracks at the end of albums?

I have only noticed this behaviour after the last few updates

Currently  the OS on the devices is 82.3-60160

It happens with the

Android  v80.15.01

IPAD    v80.14.09  (later version not avail yet in my region)

and PC version 16.5.1

    That’s odd!

    The screenshot is from the 80.x IOS Sonos app.  It’s 3 Doors Down: Away From the Sun from the Artist category.  All 12 tracks show.  I looked at the Album view and it was the same.

    My NAS is the SonicTransporter i5.  The folder structure is Storage - Music - Genre - Artist - Albums.  The tagging software is DbPoweramp.  Tags are Artist - Track title - Album - Track No. - Genre - Album Artist.  All other tags generated from downloads are removed.

    I have made little progress in tracking down what causes this behaviour ; 

    I have now stepped through roughly half my music library of 250 CD’s   approx (3500 tracks) and found numerous holes where 1 or more tracks are missing in the Artist and Album views although ALL the tracks appear in the folder view.

    So far I have found: 

      43 Albums have missing tracks  (approx 18%)   

              These are all single artist albums so not the compilation album issue 

      2  albums have weird blended mixtures of track numbers in the artist view, I have no idea what causes this 

      I cannot see how these albums differ to the other albums that are catalogued correctly by Sonos, they are a mix of WAV, WMA, FLAC file types.  

    I have used 

     -  MP3Tag to check all the album / album artist / track number settings and they all check out

     -  I have used two separate NAS system to check this out (one 5 years old, one brand new) and both systems generate exactly the same (incorrect) results within SONOS Artist / Album views  (deleting and rebuilding the SONOS library each time) 

      

    There is no apparent consistency in what triggers this behaviour 

     

    I did experiment with one album and converted everything from Wav to FLAC.  This resolved the issue with that one album but I really don’t want to have to spend hours converting my entire library. I also don’t know if this is a 100% solution and could use guidance from someone at SONOS.  I know that wav has limitations with tags  but this has never been an issue in the past (i.e pre Mar 2024). 

    I can’t imagine that SONOS would want to put out a communique that you have to convert everything to FLAC to get artist and album views to work correctly and use MP3tag editor to resolve the compilation album problem (separate threads on this)..   

    Neither of these two issues was a problem in the past,

    Sonos newbie here so excuse me if I’m saying anything already known. I’ve had exactly the same problem where not all tracks show in the Album view but noticed it seemed to only happen when they were wav files. The only way I could fix the problem was converting them to mp3 files and then all tracks were displayed correctly.

    Thank you for taking the time to reply,

    In the end I did spend a weekend converting all my albums to FLAC and this has cured the missing tracks issue for me.

    If you have a choice (and the disk space) I would recommend FLAC in favour of mp3 as it is lossless so you shouldn’t lose any quality from the original wav.
