Xbox Video - How to know quality sound (stereo - DD - DTS) before paying for a movie.

Yeah DTS has a much better sound range. Prefer it on my movies and games over DD 5.1.

Thank you for a fast answer!

I did everything as you said.

1) It is a 4k (mkv, m2ts) movie (i've tried many of them) with a several audio tracks. So Dolby Digital tracks (with ac3 codec) always work great, DTS dosen't... (video is playing, but without sound). I use Movies & TV app for xbox or multimedia
player.

2) Problem does not occur in games or streaming services

3) Ok. I set my HDMI autio to stereo uncompressed, optical audio selected bitstream, bitsream format DTS or DD. And it makes no difference(((

May be i should set my soundbar to TV, not to Xbox?

I have other devices connected to my Marrantz, namely chromacast and 3d blue ray player. I jus tried playing a video on youtube through chromecast. It was an iron man 3 trailer, in hd and Dolby sound. When I play this video through chromecast, my AVR shows
me the sound output options of "DOLBY PLII MOVIE" and "DTS NEO:6 cinema" in addition to "multi Chn stereo". Playing the video on either Dolby or DTS gives me proper surround sound. Then I tried playing the same video on xb1 youtube. This time the sound options
were "multi Chn in" and "multi Chn stereo". Playing the video in multi Chn outputs sound from only front, center and sub. Surround speakers don't output any sound. I tried selecting bitstream, and select DTS/ Dolby there, but same result. I don't know what
my xb1 is doing this?

Hi MattGarrad, thank you for the reply.

I've been doing a little bit of experimenting with this. The audio passthrough is definitely enabled in the general settings and has big tick. but, I've tried the audio with this disabled and enabled.

Yes, totally agree with you that there are still bitstream outputs, although these are fixed to specific formats.

Your reply above goes right to the heart of the problem.

When I have the sound output set to DTS and audio passthrough enabled, the xbox is converting the output from Netflix into DTS. This is not passing through the audio.

I've tried the following...

1. set the audio passthrough to disabled.

set the general settings to stereo - Netflix only gives me English and the amp shows Prologic.

set the general settings to DD - Netflix gives me English plus English 5.1 but no other languages and the amp shows Dolby Digital for both sound tracks.

2. set the audio passthrough to enabled.

set the general settings to stereo - Netflix gives me English plus lots of other languages and the amp shows Prologic.

set the general settings to DD - Netflix gives me English plus English 5.1 plus both formats for lots of languages and the amp always shows Dolby Digital.

set the general settings to DTS - Netflix gives me English plus English 5.1 plus both formats for lots of languages and the amp always shows DTS Surround Sound.

When Netflix is playing a movie, I also get nothing on screen anywhere that tells me that passthrough is active.

• Netflix appears to be selecting the soundtrack options from the chosen general setting not the TV info.
  

The only difference I get with passthrough enabled is that all of the other languages are available.

3. Before the update occurred!

I had four options in general settings. Bitstream Out, Stereo, DD and DTS. These are defined from the connection to the TV. I had the settings as Bitstream Out and Passthrough enabled.

Now, the interesting bit. When I started Netflix, this always gave me English, English 5.1 and all the other languages.

The amp would show as Prologic until I played a movie. at which point it remained at Prologic or changed to DD depending on the Netflix soundtrack. if you paused the movie, the soundtrack stops and the amp goes back to Prologic.

When I had set the general settings to DTS the amp showed as DTS. That is until you played a 5.1 movie and then it would change to DD. When you paused, it went back to DTS. It went back to DD when you continued the movie. If you played a stereo movie the amp changed to Prologic. This means the amp was picking up the bitstream format directly from Netflix.

My understanding is that the Bitstream Out was just sending the sound As Is.

There seems to be two options from all this.

a. Microsoft simply puts back the Bitstream Out and everything works again.

and/or

b. Netflix needs to push out a new version of the app which correctly determines the available sound formats from the TV info. This then pushes the sound through the xbox without the conversion occurring i.e. does it now need to account for whatever changed in the xbox update.

In either case, it's not our fault. We, the consumers, haven't created this problem. There are no firmware updates or anything like that outside of the xbox which will fix it.

(apologies for the long reply)

Many Thanks,

Dave

Similar issue here, but i can hear a crankling sound (especially with the dashboard sounds) instead of no audio.

It happens with bitstream dts and dd (stereo is ok) and it happens both with digital optical and hdmi.

I also tried my amplifier with another dts system via optical and it works good. Tried different cables too.

Please, help!
