i am running MC 24.0.69 and streaming files through an Oppo UHD-205 through a wired network with the files stored on a NAS. When i navigate to .FLAC files through JRiver, the files appear as .mp3. I also have Plex running on the NAS, and if i navigate through Plex, the files correctly show as .flac files. Is there something in the output settings in JRiver that could be converting the files? Or does JRiver not pass that metadata through to to the Oppo?
