XBOX digital audio and XBOX Blu Ray app audio

I’m going through this on the Sonos support forum now. While I was running a couple of checks, I realised that I had it a little bit wrong here:

With bitstream, there is no audio lag when playing blu-rays and I do NOT tell the Xbox to allow the receiver to decode the audio.

There is audio lag when playing games with this setup.

If I tell the Xbox to allow the receiver to decode blu-ray audio and the audio is being output through HDMI, the audio plays but the blu-ray picture freezes. I don’t believe this is an issue with the tv or Sonos because i can still move through the pop-up
menus with the picture frozen in the background and the sound playing.

If I disable the HDMI audio and use the Xbox’s optical output directly, it works as per the previous (blu-rays fine, games lagging).

You have the option of using the Dolby Atmos app that has this possibility.
You can find this app on the Xbox Store.

use the dolby atmos apy it or buy a headphone that have dolby atmos

I have tried both options of "allow passthrough". Neither makes any difference.

Just to be clear, I do not have any problems with DTS-HD Master Audio. The issue is only with DTS Digital Surround and only for DVD's. I have actually never seen a Blu-ray disc with DTS Digital Surround, as Blu-ray discs generally have DTS-HD Master Audio or uncompressed PCM audio.

I have the same question. I use my Xbox One to watch Blu-rays, but I want the best audio experience on my VIZIO S4251w-B4 5.1 Soundbar with Wireless Subwoofer and Satellite Speakers. Which optical audio settings are Xbox One audio settings are best to
watch a Blu ray like Inception?
