I can not figure out how to get Atmos audio music to play from specifically Amazon Music app built in to the receiver. It will not play Atmos encoded music or atleast the amp does not show that it is decoding it. From my cell phone Amazon app I can see the music is encoded but when I pull it up through MusiCast it only shows HD and the decoder never comes on. Also I have an LG C1 OLED that has apps including Amazon Music. And again I cant stream Atmos. Netflix, Apple, etc video apps all work perfectly presenting Dolby Vision and Atmos with no issue. The decoder comes on without problem. How is everyone listening to Atmos music? Am I missing something?
