What Surround Sound Modes Are Available?

[JackBowman 18]

Please forgive me if this is an answered question. I was wondering what sound modes are supported. I use a Roku Ultra connected via HDMI to Sony AV. So far I am getting the following...

 

1. Dolby Digital

2 Dolby D+

3. DTS

I am not able to Get TrueHD or DTS-HD. They simply playback in Dolby Digital or DTS. They sound great but but my Sony Receiver does not reflect the modes on it's display. I have downloaded many test MKV files from https://thedigitaltheater.com/ for testing purposes. I would appreciate some education on this subject. Thank you in advance. I am really enjoying the forum here!  

 

Sincerely,

Jack

Your Roku can't handle TrueHD or DTS-HD.

An Nvidia Shield is the best/only? option for those Blu Ray derived audio formats.

Odd that they say they are supported under the Roku settings/Audio/Digital Output format/Auto option. I wonder if this is a detect function but not playback? Thanks for the info!

They've managed to confuse everyone with that screen: https://community.roku.com/t5/Roku-Device-Features-Settings-Updates/Roku-Dolby-TrueHD-Now-Listed-as-a-Supported-Format/td-p/563990

 

But the specs haven't change: https://developer.roku.com/docs/specs/media/streaming-specifications.md

And I'll preemptively mention that the Atmos support is *only* over DD+, not when packaged with TrueHD.

You have been so helpful helping me understand this. I appreciate it very much! Looks like I will be looking for a deal on the Nvidia Shield. I have been a Roku user for years but I still have two more HDMI ports in the Sony Receiver, so here we go. Thanks again.
