Sony receiver displaying Dolby Digital signal, however all sound is being routed through front left and center speaker. The same is replicated when testing the surround sound in the Settings/Support.
This happened just recently, the Channels app has been working properly for over a year now. Nothing physical has changed with my setup. All other apps (AppleTV+, Netflix, Amazon Prime, HBO Max, Disney+) are producing correct surround sound from the correct speakers.
A little about my setup. Apple TV -> HDMI -> Samsung TV (audio settings are correct, other apps produce surround sound) -> HDMI -> Sony receiver. I wish I could connect my Apple TV directly to my Sony Receiver, however it doesn't support HDR passthrough.
Did something happen in either a Channels or iOS update that broke my surround sound?
Thank you so much for the help!
