[Kodi 17 Krypton] NO Master Audio and DTS-HD

So i installed the most recent release of Kodi 17 Beta. I am using a properly configured windows 7 computer and was running 16.1 with no problems. With 17 however I get now Master HD or DTS-HD Audio using my Nvidia GT430. I checke and reset all settings and reconfigured a few times. I finally reverted back to 16.1 and all is well.
