I have a similar problem with my Marantz 8805 processor. The output signal on my processor reflects a PCM reception and thus reduces the sound to stereo. This is on Netflix Vikings Valhalla. My system is a regular 5.1. I don’t have Dolby Atmos. I have Wilson speakers with Krell amps. The Marantz processor is about two years old and capable of processing most signals. I have tried Auto and Passthrough to no avail. What am I missing? Can someone please explain to me the audio capabilities and limitations of the newest Roku Ultra when directly connected to my processor? Thanks in advance.
For your situation, your receiver might not be set in the correct mode or on the correct input for 5.1 considering those restrictions. Although, that's separate from my question about DTS support.
If you made a separate thread with your question, I'm sure you're more likely to get an adequate response.
