FWIW I’m not experiencing the issue mentioned. It’s working okay here with both Android and iOS tablets/phones as Sonos App controllers with my local NAS library. See attached…

Maybe it’s a the NAS sharing protocol - Sonos now uses SMBv2 (or higher) only if you’re perhaps not aware of that already?

It’s very odd and now becoming inconsistent. I can access and play any song on my NAS if I browse by folder or use the Artist or Album fields to select music to play. Trying to play those same songs via the Songs content category now sometimes works and sometimes does not (play button has endless cycling animation until it seems to timeout). Despite lots of testing and experimenting, nothing would play until now, so I’m even more confused.

I can scroll down the song list to songs which haven’t loaded album art and it eventually populates. I can search for those songs thru Sonos and play them no problem as well. I was able to shuffle and play all songs as recently as a few weeks ago, and I’ve been updating my system and app regularly.

Here’s a screen recording for more context.

​@Sherv,

Maybe try a rescan/reindex of the library via the new Sonos App and wait until that finishes and see if that improves things first you. 
 

Hope that fixes things and Happy New Year too.

Happy new year to you as well. I have reacanned several times as part of the troubleshooting process, to no avail.

What size (number of tracks) are held in your library? Are you noticing any common-denominators with tracks that don’t play? Do you know what their bitrates are and have you sample-checked their metadata/tags.

Also, does the NAS use a recycle bin feature?- I’ve seen some users report issues with these features and emptying the bin and re-indexing can (apparently) resolve the issue.

My own NAS doesn’t have a bin option, so can’t confirm anything here, but perhaps double check things before deleting things permanently (obviously). 

No recycle bin on my NAS.

20,601 mp3 files, mostly VBR, a few 320k. No common denominators that I can tell, so far. Tags havent been touched in years.

That sounds similar to my own NAS library - not sure why you are seeing the issues. Library here has been pretty much fine, even shortly after the May 7th update - I just mostly had the compilations ‘Album Artist’ issue that was solved recently, but I had to switch my compilations to group by Album Artist using the desktop App (see attached) … but that doesn’t really sound like the issue you’ve described.

That said, are all the tracks that don’t play, from a ‘compilation’ album, or are other types of albums affected too?

There doesn’t seem to be any difference between compilation and single artist albums. Could be worth setting up a smaller library and seeing if maybe Sonos is choking on the number of tracks but I’m not willing to risk creating further problems by doing that.

The local library here has 25,697 tracks, so it’s possibly not that, but maybe move out a few of your Artists and their Albums to perhaps get the count down to around 18,000, or thereabouts, to see if it makes a difference - the real pain is having to rescan/reindex as that can take a while with the new App.

Other than that i can only think it’s metadata issues, but if the non-playing tracks do work okay with other Apps then I guess it must be down to Sonos.

I can't understand how metadata would affect playback when those same tracks play fine, in Sonos, when selected through other means: different id3 tag sorting, directory/folder mavigation, and playlists…. and then there have been instances where the songs play as they should when selected in Song view.The lack of consistency is puzzling.

Hi ​@Sherv 

Welcome to the Sonos Community!

Thank you for flagging this behaviour - I have been able to replicate it on my own system and have reported it. I will update this thread once I hear more, but in the meantime, I think you can cease troubleshooting steps.

It does seem that Add to Queue, Replace Queue and Play Now all work (in the 3 dot menu for each track). Weirdly, tapping a track in Songs view after using Replace Queue works, but only once.

I hope this helps.
