Bug Report Indexing of Audio Genres and missing album tracks
Examining the metadata (outside Serviio) for these tracks is correct.
This appears to be an occasional error in the indexing process.
By editing the metadata say by adding a space in the comment field results in the track being re-indexed and classified in its correct genres category (without any change having been made to the Genres).
Usually there may be just one or two tracks from an album (bearing in mind an album usually has the same genres set for all tracks) in the "Unknown" category.
I can see no pattern and the tracks come from differing Genres.
IMPORTANTLY I have just discovered that these tracks are not in the Artist/Album lists !!!!!! i.e. THEY ARE MISSING FROM THE ALBUMS in the Control App.
(this is not a new issue as I have used my workaround that clears them up in the past. I was not aware they were missing from the albums).
Force Refresh does not appear to resolve this issue. Also if you do not have Genres enabled as a display option you may never know the tracks are missing.
I think this is an urgent bug.
