Hello, I'm setting up my Yamaha RX-A2050 and I cant figure out how to get it set to play Dolby Atmos. I'm playing the San Andreas Blu Ray which has Dolby Atmos through my Xbox One to my receiver. I'm running a 7.1.2 set up with two in ceiling speakers. I'm sure its just something in the receivers settings but I cant figure out what I'm doing wrong. Any help or advice would be great.
