Surround sound

[FritzB001]

I am using Plex on my PS4 (client) and Synology NAS (server) and upgraded my AV-System (using a Marantz SR7013-Receiver) to Atmos. Only getting stereo sound is a desaster. Please reastablish passthrough ASAP!

No passthrough!?

I am using Plex on my PS4 (client) and Synology NAS (server) and upgraded my AV-System (using a Marantz SR7013-Receiver) to Atmos. Only getting stereo sound is a desaster. How can I reastablish passthrough? (replied a post with the same text but after that I thought it would be better to start a new topic)
