I just added my PC to the HDMI In and struggled to get this working too but eventually I got the sequence right and It allows me to configure Dolby Atmos Home Theater. You have to go into Oppo sound properties on PC and enable Spatial Audio. Then you exit and go back into configure and choose 7.1. After that you should be able to choose/configure Atmos.
