Same issue here, with the new 2024 Ultra 4850x...I bought five of these, and was planning to replace my five Ultra 4800x units with them. So...with the exact same setup (paired with Sony Bravia 90L series TV and Sony Bravia Theater Bar 8), I cannot get the 4850x to output or pass-through anything more than 2.0 channel audio. Tried every combination of settings on the Roku, the TV, and the soundbar. Finally, I subbed the 4800x back in, and all is well again, Dolby Atmos all day long. So frustrating.
If you select and HIGHLIGHT Settings/Audio/Digital output format = Passthrough, what formats are detected? (The box on the right will state the detected formats).
If you don't see at least DD+ (Dolby Digital+) listed, you wont be getting 5.1 (or Atmos) for almost every streaming service/app (The Roku Channel, P+, and Apple TV aside).
However, unfortunately OS14 (and most RokuOS versions/builds) has Sound Modes enabled by default (including on a new 4850), and these disable multichannel output, so you need to disable them:
During playback press Options (*)/Sound Settings/Customize sound modes/Volume Leveling & Dialog Enhancement = Off
NOTE: a Factory Reset will return RokuOS to its default configuration including Sound Modes being enabled by default, so you will need to disable them again afterwards.
Make sure sound-leveling is OFF
- Start watching something
- Press the asterisk ()* button on your Roku remote
- Select Volume mode
Set sound leveling to OFF.
I found this will defeat any Dolby/ DTS auto-detect and set any movie to stereo. It also compresses everything into a loud jumbled mess.
