New magnifi mini sound bar Dolby content green light not working when viewing blu Ray dvd

New magnifi mini sound bar Dolby content green light does not turn green when blu Ray dvd is played with content. However, it does come on when a regular dvd is played. Sound bar is connected to Sony Bravia 4K tv through hdmi arc connection. Bravia sync (CEC) is enabled. What do I need to do? Is unit defective? I would hate to return it if I can get it to work. Hope there is an answer!
