Sonos issues and connectivity

I think you may have hit some metadata limit. Don't forget it’s the speakers that index, so your S1 speakers will probably be storing less metadata than S2 speakers use. We know they’ve made changes in the S2 firmware here to support the new app’s search as they broke indexing of compilation albums. 

If you can on the Synology, move a chunk of data off the Sonos share and see if the S2 library suddenly appears. If it does, that would confirm the issue is around that, although if it’s all there in the desktop controller, it again points to some weird issue in the S2 mobile app. I would check from the desktop controller that all tracks seem to be there just incase it’s better at handling an incomplete library. 

At 62k tracks you will be close the S1 limits too, as much depends on overall metadata and how much you add etc. 

A copy of the library file names and SONOS Playlists is stored in each player. All of the controllers could be uninstalled without corrupting the library. (Of course you’d need to re-install a controller before being able to select tracks for play, but correctly selected tracks would continue to play without the controllers.) With short metadata a full 65,000 track library is easy. With long metadata, I’ve seen some users report running out of space in the 30K range.

Some ripping programs use excessive metadata. I’ve seen some that will dump the full first stanza of an opera into the metadata when track file names of 00001.flac through 65000.flac would suffice.

Much older versions of S1 could display the amount of RAM used for library metadata. Currently, this is visible only to SONOS support in the diagnostics.

Well the library has appeared in my S2 app now, so that’s a bonus i will definately take some of the pointers and check if everything is showing that’s on my NAS in the app. many thanks for the all the help and pointers, much appreciated.

Now i need to try and resolve the bluetooth turntable only working with my Roam and not syncing to the new S5, as that’s slightly tedious. 

Not sure what you mean by “sync”. If you’re trying to Bluetooth connect to a Five you’re out of luck as it doesn’t support Bluetooth. Otherwise, select the Roam, get the turntable playing, then group the Five with the Roam. The music the Roam is playing is then sent to the Five too. If you select the Five first, then group the Roam, the Five’s input is selected and the turntable input ceases. 

I appreciate that, as that’s how i have been using the setup, by selecting the turntable, then the Roam, then going into the Sonos S2 app, selecting both speakers then hitting apply, as soon as i do this the music stops playing on the Roam and of course nothing comes out of the S5. 

When Groping Rooms, start with the ROAM, then add the FIVE to the GROUP. FIVE will then play (in sync) anything playing through ROAM.
