I have a Sonos Move, One SL, and Port and a Brennan B2 music server with my CD collection that has been working perfectly for almost a year. However, three days ago I noticed that some songs can not be found by my Sonos in the Brennan server. The most puzzling thing is that the “trouble” songs play in my One SL when it is the only speaker but not if I make the Move or Port the sole output. I notice that the problem songs have characters like ñ, accents, and/or question/exclamation marks in their titles. I reset all my Sonos components and that by itself does not fix the problem neither does re-indexing. The problem goes away only when I remove the offending characters from the name of the songs in the Brennan B2 music server. I have not made any changes in my system to have caused this problem. Has there been lately an autonomous update in the firmware of my Sonos components? How can I fix it? I would prefer not having to go through my full library in my server removing offending characters that were not a problem before. Any help on this matter will be highly appreciated.

We are aware of an issue that causes systems with a One SL to fail to play back files from a music share on a NAS that contain a special character either in file path, or filename such as Ä, Ö and Ü. We are investigating the issue, but have no timeline to share. In the meantime, the workaround is to rename the files/folders to remove the special characters.
