In the new desktop app, Sonos will play songs from my music library as it always has.  Towards the end of a song, though, I will frequently get a popup saying something like Unable to play, the song is not encoded correctly.  This happens after the song has played and does not interrupt the playback.  The message appears briefly, then vanishes.  The app will then move to the next track in the queue as expected.

Setup:

• Room 1: Sonos Ray + 2x Play:1 + Sub.
• Room 2: Sonos Beam + 2x Play:1 + Sub.
• Each room connected to a television via fiber optic cable.
• Desktop app running on a Mac Mini M2 system under macOS Sonoma.
• Music library on a Linux server with access via Samba (CIFS).
• Music library is large, 14,000+ tracks.
• Tracks mostly FLAC, 16-bit, 44.1 kHz, some Mp3 and Apple M4a.  The encoding does not seem to matter.  The message will appear for any.
• WiFi networking throughout.

Before the new app, I would sometimes get the unable to play due to encoding message, but it could always be traced to some problem with the track file itself and fixed easily.  In these cases, the system would completely refuse to play the track.  The new problem is definitely different.  The tracks play normally on other players.

This is not a showstopper, but as issues with the new app are being raised, I thought I would raise it also.

I’m rather more concerned about the problem with duplicated albums in the music library due to mismatch between album artist and track artist, as has been reported elsewhere.  I’m eagerly awaiting the fix for that one.
