Replacing music files with better copies in Plex could leave Music Assistant trying to play the deleted originals. Library synchronization removes those stale links when the source reports its current collection, so a metadata match no longer leaves a dead copy competing with its replacement.
RyanAtTanagra found 600 of 2,324 album links pointing to deleted items after upgrading a Plex library to FLAC. The cleanup follows the library-sync deletion setting, waits for a complete synchronization and preserves items the source says it skipped. Streaming-service catalogs and Music Assistant’s direct local-files source are outside this cleanup.
This is RyanAtTanagra’s first contribution to the Music Assistant server, reviewed by Marcel van der Veldt.
