Prior to running Emby full time, I tested it out on a machine running CentOS. As soon as I pointed it to the music files, every last one populated no problem. Since then, I installed Emby to Ubuntu Server 16.04 and only a miniscule fraction of that music collection shows up. 370 Artists showed up fine before, but on Ubuntu Server, only 27 show up. Can anyone illuminate the differences that may have caused such a major issue?
