Sound not working on a single channel Part 2

Have found that this appears to be fixed in the latest version of FFmpeg.
Have tried to get Jellyfin to use the new version by replacing the the ffmpeg.exe and ffmpegprobe.exe in the Jellyfin file system. It loads ok but complains that it is the wrong version.
Can you tell me if the latest FFmpeg will be included in the next release?
