Roku Ultra 5.1 audio issues.

[DFQForce4]

I have a Sony STR-DH550 with which has HDMI 1.4. I have a 5.1 set up using the Sony Core series L and R towers,center channel and the bookshelves for the surrounds,and the Sony VA-S315 75 watt active subwoofer. The display is a Samsung KS9800,but it will soon be swapped for a Samsung S95C. Ok here is the issue I am running into the TV(s) are at least HDMI 2.0 the reciever is HDMI 1.4,so 4K HDR 10-bit color devices have to be hooked into the tv directly. Because of this I am using HDMI ARC for audio. The Roku Ultra (2019) model is plugged into the tv directly and the audio is through HDMI ARC. The Roku says it says DD plus and DTS are available,yet when I go to play 5.1 content from a streaming service it keeps outputting as LPCM 2.0 and not DD Plus or DTS 5.1. Yes any night mode and audio leveling on the Roku are turned off. My PS5 and Series X are hooked up with the same proccess and I am not having audio issues with those. Is any one else have a similar issue any help would be nice.

What streaming services are you using and are you paying for the appropriate codec/video combo? What are your options in the Roku tv for audio output? Not all tvs output the multich codecs either (my old Samsungs don't unless it's OTA content).

Paramount Plus,and Prime Video highest tiers. Yes the TV supports DD and DTS 5.1 through ARC. I have read other forums and tried the solutions and they have not worked. Also my PS5 is hooked the same way and 5.1 audio plays just fine from 5.1 sources. The audio options are stereo and auto. Under auto it says DD and DTS are auto detected. I have read I could try putting it on "auto passthrough" but this model of Roku doesn't have that option.

I prefer my streamers not in the tv myself due to limitations of app/tv possible. If the tv does support it via ARC not sure why you can't use it, tho.

Same normally I would just hook it to the AVR HDMI inputs directly but if I do that then I am limites to 1080p SDR instead of 4k HDR.

You sure that isn't the root of your problem?

I'm sure if that was the root of the problem the PS5 would be having the same issue,but it isn't.

They don't particularly share the same protocols....

It's hard for us to know what you have already tried. I would try and break down where the issue is occurring.

Run the Roku through your sony AVR; roku to AVR and AVR to TV both via HDMI. You should still have a 4k picture. Is the sound what you expect, DD?

That's what I am currently doing I think. The Roku HDMI is going into one of the tv's HDMI inputs,I have the AVR's HDMI out plugged into the tv's HDMI ARC input.
