Additional information

Navidrome server ver 0.61.1

i’ve tried downgrading to Symfonium 13.6.5a , experienced the same issue

tried getting “content-disposition” directly from the server using curl, received proper filename -

content-disposition: attachment; filename=“song.flac”

The issue started after recent upgrade to Navidrome - i believe it started from 0.60 (meaning, 0.59 worked okay)
The problem affects both HTTP and HTTPS connections, and both M4A and FLAC files.

Since Navidrome v0.60/v0.61 introduced changes to the Subsonic API response structure (including new go-taglib extractor and Child response field changes), it’s possible the download response format changed in a way Symfonium doesn’t handle.

AutoTranscodeDownloadvariable in Navidrome is set tofalse

The server sends Content-Disposition: attachment; filename="song.flac" but Symfonium saves the file as song - the base filename is preserved but the extension is stripped. This suggests Symfonium reads the header correctly but drops the extension when writing to disk.
