Offline Sync doesn't work for some files

[Stormrider959 0]

Hi

 

Since a while the sync progress of my music library is stuck (at around 60%). Every scheduled sync I can see the notifications for the missing files, but they won't download.

 

Here's a part of the log which shows a NullPointerException for one of the files. In the music folder there are currently 32 "Various_Artists (some number)" folders.

I've tried to create another file with the name stated in the log and I've copied the file from the share to the same location with TotalCommander, both were successfulll.

My phone currently is on Android 8.0 but the issue was already there earlier.

 

The corresponding server log doesn't seem suspicious:

All affected files seem to have Various Artists as album artist.

 

The app (verson 2.9.76) and the server (version 3.2.60.0) are on the current stable release, but the issue was already present in earlier versions.

 

Do you have an idea how to fix this?

 

Thanks a lot

I forgot to mention that new files in the library sync fine.

[Luke 37065]

@@Stormrider959 can you please let me know if this is still an issue on the latest version of the app? Thanks !

[Luke 37065]

If it is still happening, can you try deleting all those various_artists_x folders and see if that makes any difference?

[Stormrider959 0]

Hi Luke

 

Thank you for investigating this issue.

 

I recently reinstalled the emby server (the issue wasn't emby related) and resynced the music library, the issue is still there. I'm using the stable release.

Now i have the following folders on the phone:

Various_artists(1)

...

Various_artists(32)

In the first folder is one complete album. in the folders 1 - 32 is an album-subfolder with one song. Two albums are completely synced, scattered in multiple folders, the rest of the albums has one or two synced songs

 

When i delete all the various_artists-folders, the rest syncs completely without additional folders.

 

Should i try the beta?

[Luke 37065]

No, I don't think the beta server will have any impact. It's being on the latest version of the app which is more important, which you should be by now. In that case we're still looking into it then.

Hi Luke

 

I found the issue. I played around a bit with the library and the tags of the files when i realised that a few of the album artists were "Various artists" and the rest was "Various Artists". After i fixed this, i could do a complete sync. Thank you for investigating this issue.

 

Best regards

[Luke 37065]

You mean just the casing was the difference?

[Stormrider959 0]

Yes, just the casing.

 

As soon as i change one album back to "Various artists" and resync, the numbered folders reappear.
