Jelllyfin + Subfin (https://github.com/williamkray/subfin-plugin) works well, I’ve been using it with the OpenSubsonic Android apps listed in https://www.navidrome.org/apps/?platform=android&api=opensubsonic without issue. e.g. Substreamer, Tempus, Airdrome, etc. all work fine with Jellyfin + Subfin.
I’m guessing you’re not on Android or iOS since Jellyfin has apps on those platforms - but you should be able to use any Subsonic/OpenSubsonic app once set up with the plugin.
It’s mainly about the noise but the article does mention
