@jonas Many thanks. That is it. The modification time of the files was being changed. However, the that of the directory under which they sat was not being updated. A "touch" of that directory, and then "Update Changed Collection Folders" works perfectly. Thanks again. Regards Stephen Meatheringham Canberra, Australia

@jonas Many thanks for your reply and the pointer to the other issue. I have GStreamer 1.22.10. It does appear to be related to issue 1376. That gave me an idea. If I un-tick "Fade out on pause / fade in on resume", the problem does not occur. Excellent! Thanks again. Regards Stephen

I'm aware of the limitations, as far as I remember it has to do with the sqlite full text search which is used for the collection. I plan to get rid of SQL-based search for the collection entirely which means rewriting parts of the collection model and search, which I started on a few years ago, it should get rid of these limitations also. When that is done, the collection search will be similar to the playlist search, search will use a model/proxy and not SQL.
