Surround Dolby/DTS 5.1 does not work with apps like Netflix but works with games and TV

Lots of info there, not sure if its all problems now or how it was before but ill try and help.

*The bitstream option has disappeared from the audio options. I can see Stereo Uncompressed, Dolby Digital and DTS Surround.*

Dolby Digital and DTS surround are bitstream formats, so the bitstream option is still there.

*Leaving the sound as Stereo on the Xbox. I start Netflix and when I choose a movie the only option is English. English 5.1 is no longer available.*

Have you enabled 'pass app audio directly to your receiver'? its in 'additional options and disabled by default.

*When the sound is now set to DTS on the Xbox. I start Netflix and the movies gives me the same English and English 5.1 choices. but.. the amplifier displays DTS Surround Sound irrespective of choosing English or English 5.1. The English 5.1 is being converted from Dolby Digital to DTS by the Xbox!*

Yeah, you've told the Xbox to output DTS as its bitstream output, so thats what its doing, as i understand it the default ' English 5.1', would be Dolby digital 5.1 but you've asked the system to output DTS as the bitstream format so its converting it.

*When the sound is set to Dolby Digital on the Xbox. I start Netflix and the movies now give me English and English 5.1. But... the amplifies remains on Dolby Digital irrespective of choosing English or English 5.1.*

Because the system is being told to output 5.1, so that's the default output its using. try enabling 'pass app audio directly to your receiver'.

On mine setup, I've just left bitstream output as Dolby Digital ( which is a bitstream format) and all works good, i cant us DTS as my LG tv wont passthrough DTS via optical to my receiver.

Dolby 5.1 is broken for the xbox at the moment. It stopped working when xbox updated on 7 Dec 17. Microsoft is aware of the issue (so I'm told) and they are working on it.

I'm still waiting for Microsoft to fix the problem as well.

Putting it very simply for them to understand. Netflix was working brilliantly until the November update and now it's rubbish. To expand on this.

1. Before the November update. I had the audio option set to bitstream and ticked the audio passthrough checkbox.

The sound is passing into my TV and I have an optical output to a DSP-A5 amplifier. With the xbox being used for games the amp displays ProLogic for normal stereo output.

The Netflix app can be started and when you list the sound options for films you are given English and English 5.1.

When you choose English, the sound is stereo and the amplifier displays ProLogic.

When you choose English 5.1, it's surround sound and the amplifier displays Dolby Digital.

The movies and tv app works really good with this as well.

2. Microsoft released the update to 'improve the users experience'.

The bitstream option has disappeared from the audio options. I can see Stereo Uncompressed, Dolby Digital and DTS Surround.

Now, when I choose each of these options the amplifier picks this up and displays accordingly ProLogic, Dolby Digital and DTS Surround Sound.

This is where it all goes wrong.

Leaving the sound as Stereo on the xbox. I start Netflix and when I choose a movie the only option is English. English 5.1 is no longer available.

When the sound is set to Dolby Digital on the xbox. I start Netflix and the movies now give me English and English 5.1. But... the amplifies remains on Dolby Digital irrespective of choosing English or English 5.1.

When the sound is now set to DTS on the xbox. I start Netflix and the movies gives me the same English and English 5.1 choices. but.. the amplifier displays DTS Surround Sound irrespective of choosing English or English 5.1. The English 5.1 is being converted from Dolby Digital to DTS by the xbox!

3. the ONLY device which has changed is the xbox with the software update.

The TV is an older LG 55EC930V which has always been up to date on the firmware. The amplifier has no firmware to update.

Ticking and unticking the audio passthrough does bugger all.

It actually does support great 5.1 surround with optical threw the DTS Digital surround option. DTS is actually better then dolby but alot of headsets dont support DTS.

My main quesition is of inputs ad outputs> Trutle beach headphones in the 360 era took Dolby 5.1 inputs and made then Dolby Headphone Output, and was an external device that also wokred in TVs and mobvies players... aslonga as the source was Dlby sound
in. DTS didn't get coded at all, and LPCM beyond 2.0 wouldn't fit in a Toslinlk.

The Turtle Beach DTS:X headphones had DTS 2-track headpone surround outputs, but onl\y accepted Dolby-based inputs, so I can't decode Blu Rays in DTS and expec a surround sound.

It seems to me that Dolby Atmos inputs like Blu Rays sound better in dolby Atmos Headphones than DT5 5.1-DTS 7.1, LVM 5.1-7.1, and even "lesser dolby modes" 5.1-7.1

Is the Dolby Atmod Headepho0ne app suposed to take ANY of the 3flkavors and tuen them into Dolby Headphone? Or does it only work wiht Dolby Atmos movies? meaing you haver swithc the settings on every non-Atmos disc.

Finally is thee such a ting as a 2-channel headphone surround encoder that takes ANY of the brands and flavords of sound formats and send out 2-yttrack, surround heapdhone f some sort of format. I'd like that for the upstairs TV. Too many DTS movies sound
lackluster and 70% f our BD/3D colection is DTS.

I knw Sony heaadhones have a Doly and DTS input and sound better than pure uncoded 2-track LPCM, but it doesn;t sound as good as Xbox's DTS-> dDolby conversions and then letting the Turetle Beach encode it in 2-Track surrouud headphone. (By the way, does Xbox
One do LPCM 7.1-> Dolby 7.1 ?)
