Switching back to Roku from an Apple TV 4K in our living room. TV is a 55S405 Roku TV. Having issues with audio options.
If I set to auto, only DD and DTS show as available and it appears that most sound (even Roku system sounds) are outputted in DD, unless it's DTS content. Netflix, Hulu and Vudu all then appear to output in DD.
If I set to passthrough, the same audio options show as available (still no DD+, AVR supports it). Playing DD and DTS content in Plex will output correctly. However, most everything else appears to output in PCM 5.1? And Vudu will not output in 5.1.
I am able to select custome and then enable DD+ and DTS, but then I seem to have the first problem. Everything that isn't DTS is output in DD+ -- even apps like Sling, which do not output in DD whatsoever.
However, if I plug in a Roku Streaming Stick 4K+, everything seems to work as expected.
Setting audio to audio shows DD, DD+ and DTS available. System sounds and apps like Sling appear to output in PCM as expected, but Netflix outputs DD+, and DD and DTS content in Plex play correctly.
Any ideas? It sounds silly, but we're making the switch back to Roku because some of the apps we use are just easier to use -- especially Sling.
