With the 18.5 update I can not change the audio output device setting to android raw or EAC 3 or change audio pass through. I can change all the other settings such as number of speakers 7.1 and the codecs that my Samsung soundbar HW-K180 supports with wireless rear speakers and that supports Dolby Atmos. But, with 18.5 I have not been able to get any Dolby Atmos sound through my sound system. Are the setting different for 18.5 or is this a bug between Kodi and the Shield?

Kodi never had this feature. Whatever you had before was not official kodi. Though, there is some hope for you as I have implemented this feature and PRd it to kodi. Sadly no reaction until now, if it's wanted in kodi. I include it in my fritschfiretv test versions - install that if you need this feature. 

My soundbar supports dts-hd but does not announce it properly to my shield so it does not show up as available in nvidia shield hdmi settiing and when I enable dts-hd in normal kodi the dts-hd stream was not getting passed through and I was getting not getting any sound. With the raw audio option in your build I got back dts-hd playback. Thanks for this I hope your pr gets added to kodi.
