OP I'm fairly certain your issue is with your music file metadata rather than the software. I suspect if you clean it with musicbrainz picard or open it with a tag editor you will find its using slightly different characters in different metadata fields. You can test this by loading up one of the offending files, clearing all of its metadata and see if that looks better!

This is a great idea and reading through all these other replies points the same direction. I will try just that!
Thanks! Checking it out right now!
I am using Navidrome and if it has significant bugs, I haven’t run into them yet.
I use Navidrome with symfonium and they're great
I use Feishin on desktop instead of the webapp. But otherwise - same setup!
This is my current setup, couldn't recommended it more!
Navidrome + airsonic-refix for Web play and symfomium for mobile.
This but just JF instead of Navidrome
Navidrome uses the subsonic API but is actively developed and works great.
Ok so I just installed Navidrome and the web UI looks modern and promising. However it seems to have the same bug as other services I tried earlier: If the artist name or album name has any umlaut letters (like ä, ö, ü) then all tracks on that album are displayed twice on my mobile client (have tried substreamer, ultrasonic, tempus). Any idea what's causing that for me?
I have a lot of music using umlaut and all other kinds of accented characters, even Japanese characters, and never had issues with them. Try symfonium client and see it you have the issue. I'll check tempus with my server to see it there's anything wrong.
I'm using Navidrome with Ultrasonic and Tempo on my phone, and have no such issue.
If you use Tempo I'd recommend switching to Tempus, a fork that is actively maintained. Tempo has been unmaintained for a few months now.
Thank you, already did so, when I've skimmed this thread earlier. Tempo was my second choice so far, Ultrasonic has worked better with my OS and headphones so far (usability-wise). Will see how Tempus works out.
I don't have any solution for you, but I'm just adding some information to the conversation; I use Gonic as a server and Ultrasonic as a client and it does not have any issues displaying umlaut or any other special characters.
I'm using Navidrome and Symfonium on my phone, I have no issues with any umlaut or special characters (å ä ö, japanese, korean, etc) displaying double, did a double-check now as well. Don't think I had any issues when using tempo either. Things I would check (if not already done): Are the songs / albums tagged correctly Are multiple sources active in the client?
Navidrome checks all my boxes. I don't seem to have the same issues you are having with umlaut letters tho. I'd check tags/metadata. MusicBrainz, Mp3tag, Foobar2000, Beets, can help with that.
Mainly jellyfin and I have a navidrome backup
I heard of Navidrome, never used it. Jellyfin works as well.
The client is maybe more inportant, can recomment Symphonium.
Nextcloud has an app called Music which contains subsonic and ampache servers.
I've been using Finamp for a few months now. I like the beta version that allows me to download music to my phone for offline use. I added Audiomuse and I really like the smart playlist creations. 10 outta 10
There's Swingmusic and Funkwhale, the former closer to Navidrome, the latter with... nice features (federation, built in library management) and issues (slow development cycle, bugridden Android app).
Moved from subsonic to jellyfin, never looked back. Jellyfin does music and movies and TV shows, the only bit I miss is jukebox mode
I use Jellyfin with the Symfonium mobile client.
Navidrome is popular but does not support multi-tags for some fields, like artists.
Navidrome does support multi-tags since a few updates ago.
Neat! That was a dealbreaker back when I last tried it.
