Order songs by file name when browsing folders via Subsonic

[grisumedia]

I'd like to use the Android app Symfonium using the Subsonic API. Unfortunately, the files in the folders are always ordered by their title. Symfonium does not allow to change the file order. As I understand from a ticket in the Symfonium support forum, the order comes from the server.
I would expect that the files are in the order of their name, not ordered by title.
Is it possible to fix that or to make that configurable?

Yes, sorting by the file name would make sense when browsing by the folder structure, and that's actually what our web UI does on the Folders view. But the Subsonic API sorts in this case by the song title as you have noticed.

If, instead, the user is browsing by the metadata, then sorting by metadata is sensible. In that case, our current logic in Subsonic API is such that the primary sort key is the disk number, secondary key is track number, and tertiary key is the song title.

I agree, different sortings in different views completely make sense. And, if it's possible, it would maybe also be nice so see the file names instead of the title when browsing by folders.
