Weird Passthrough Problem

All,

Yet another Passthrough problem. I have been using KODI/XMBC for years. I recently upgraded up to the new Beta 5 build. All of my passthrough settings are the same but for some reason Kodi is now decoding my audio signal. I use to see DTS-HD on my reciever but now I see multi ch in. I have searched Kodis help documentation, forums, and even google for help. I am at a loss. I have no clue whats going on. Here is my build:
