Hi @Mind.E 

Welcome to the Sonos Community!

Sonos has a playlist limit of a combined total of 10,000 tracks, across all playlists. With 300 playlists in existence, you’d only need an average of 33 tracks per playlist to hit that limit, so I think it is entirely possible that this is where the problem lies.

However, Ventura is not yet fully supported by Sonos, so it’s also possible that it is somehow causing these problems - we are working on bringing full Ventura support to Sonos.

I recommend the first thing you do is check for duplicated playlists - if there are any, these will be the obvious candidates for deletion.

I also recommend you get in touch with our technical support team, who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports - there should be some additional information to help identify the root problem.

I hope this helps.

The size of “metadata” (artist, track title, composer, etc.) is a consideration. Excessive metadata will exhaust player memory before reaching any hard limit. I have a collection of short metadata data cuts and just to be mean, I cooked up a playlist of 10000 tracks and loaded into the Queue six times, for a Queue of 60000 tracks. This 10000 track playlist is in addition to my regular (shorter) playlists, that I’ve been using for many years.

@Corry P That is very helpful information.  Thank you.  @buzz also thank you.  If I had to guess, I would say I shave more than 10,000 tracks in those playlists.

HOWEVER, here is the interesting wrinkle…

I have 2 brand new computers, both on Ventura, each hosting the exact same, identical library (synced to the Apple Cloud)…

I just set up the new MacMini over the weekend at our primary residence - legacy sonos system with 9+ zones and over 15 devices.  MacMini is running S1 Controller.  I have ZERO issues.  Library was re-assigned and updated completely on the first try with all playlists.  

Last week, the MacBook Pro, which hosts the identical library at our second home, with newer Sonos devices (only 3 zones, 4 devices), running S2 Controller is the problem.  It will NOT update the library because of the playlist issue.  (Separately, I’ve had major IP issues with these devices staying on the network, which I was finally able to resolve prior to updating the library.)

So this leads me to believe the 10,000 song limit in playlists might actually be an S2 Contoller limitation. Can you confirm this?  And if so, why not raise the limit?

Thanks again,

Mark

Hi @Mind.E 

S2 devices have more RAM than S1 devices, so if anything, it should be the other way around - though to be clear, the limitation is the same on both systems. Your report is interesting, however.

Could you please try re-indexing your music library on your S2 system once more, and, when it fails, submit a support diagnostic? Once done, please reply here at your convenience with the given number. Thanks.

@Corry P Thank you.  Then I suspect it’s got something to do with my laptop, which has a lot more software on it, particularly in the ‘Music” folder, which also contains files for Logic and Ableton Live. Perhaps Sonos is confused by that?  In both compters, the “Music” folder has 2 folder in it: a 2nd “Music” folder which contains the Library.xml and also “iTunes Music” folder which contains all the actual music files.  So when I index, I have to point Sonos to the higher level “Music” folder so it can find both the library and the files.  

Anyway, I will re-index as you suggest, but it will Memorial Day before am at that location again.  Please leave this thread open.

Thanks again,

Mark

Hi @Mind.E 

I wouldn’t want to speculate, but if there are extra files there, then sure - it’s possible. I would also look out for a duplicated .xml file (perhaps one copy being in a parent directory) - that would certainly cause a problem, and it would only take one extra file to do so.

No hurry - as long as you don’t take 3 months, the thread will remain open!
