I don't know if this is an amateur mistake I am making or if this has been discussed before. I have a Sony X850E smart tv hooked to a Yamaha HTR-6130 Reciever. I have never really had issues with Netflix or Amazon prime video sending the Dolby Digital 5.1 signal to the receiver through a digital optical cable. I seem to be running into an issue with the movies anywhere app and disney+ streaming content. The media will start to play and the receiver will show dolby digital 5.1 for maybe 2 seconds then switches to PCM stereo. I have tried switching all the settings on tv and Reciever and nothing seems to fix the issue.
Thanks in advance for any help
