XR-75x94K DTS Passthrough Problem

[ianrattew]

My problem I have is that DTS HD-Master Audio is not being passed through to my AV receiver when appropriate material is played from an app on the TV. I have a Denon x2700H AV receiver and an Nvidia Shield TV device  directly attached to the TV. TV to AVR is via eARC HDMI.

When I play a DTS-HDMA source from any app on the TV (PLEX or File Manager or Media Player) the audio is not passed through. DTS HD_Master Audio is downmixed to  DTS.  If I play the same source from the Nvidia Shield TV (Itself an Android device)  DTS HD-MA is correctly passed through and this is shown on the Denon AVR. So "Passthrough" works but not direct play.

The same occurs whether the Digital Output is Auto1, Auto2 or PCM. Passthrough=auto. Atmos and Dolby codes passthrough is OK so connectivity is not the issue.

Any thoughts please? I bought the TV specifically to play DTS HD-MA so I am rather dissapointed if this cannot be corrected. I was hoping to retire the Nvidia Shield.

Thanks,

Ian

I heard back from Sony today. They asked questions they already had the answers too. I'm quite shocked by the lasck of responsive and support. I thought the Sony brand was better.

1- Did you enable eARC mode? YES as evidenced in photo upload

2- Did you also enable Pass through mode? YES as evidenced in photo upload

3- Do you have HDMI signal format set to standadrd or enhanced? YES as evidenced in photo upload

4- Please ensure that you are using a certified high speed HDMI cable? Can we test a different one? YES YES DONE IT IS NOT A CABLE ISSUE. ATMOS IS PASSED, AS IN NVIDIA SHEILD TV THROUGH AS EXPLAINED

5- What is the model of the audio system used? Can we test a different one? DENON 2700H. NO. IT IS NOT THE AVR, AS I EXPLAINED

...and then what happened? 

Are they investigating it for you?

Hi Jumpsuit,

thanks for your input.

I was told  that the issue had been sent to a specialist team but there has been no investigation - they simply can't have read my feedback. All the information they asked for was provided.

They recieved a detailed incident report including an explanation and screenshots of my settings following my own troubleshooting which evidences that the issue is the TV software. But they simply asked the most basic of questions that are detailed in the information I sent. They simply can not have read it.

A  software technician (and geeks) will understand immediately what I am saying. The first question is does the TV play DTS HD-MA video material via an app such as Plex, Media Player or File Manager and passthrough that audio to an AVR or soundbar? If it does maybe I am doing something wrong. If it doesn't the marketing and the Manuals are misleading.

DTS HDMA does work if I play the material from my Nvidia Sheild TV (direct into the TV)which rules out Cable, eARC, HDMI settings and receiver capability. BTW Atmos works fine in all instances; External, streaming and apps.

AFAIK the TV is able to passthrough lossless audio (as in the Nvidia use case) but not to send directly the same to an avr. These are the audio  codec and sampling rate the internal app are able to manage https://helpguide.sony.net/tv/jaep1/v1/en/04-01-03_04.html

Hi Roob,

Thanks for your feedback. I thought I had already replied to you but I must have forgotten to hit "Post".

The audio streams I am playing do comply with those sample rates and also have mainstream bitrates. The link you refered to is actually codecs suported for playing from USB devices.

I suspect that my experience is the result of the way the TV responds to the internal audio streams presented it to it which it processes on an app by app basis rather than one rule for all. I see different capablities from Bravia Core (DTS IMAX Format), Netflix and Amazon (Dolby) streaming apps as opposed to local client apps such as Plex, File Managers, Media Players

My specific query is "can the TV itself, rather than an external input, present DTS HDMA audio or a DTS HDMA sourced bitsream to the AVR via the earc connection.

I have been promised three call backs now but I'm still waiting. It just requires a simple yes or no from Sony. I shall persist and revert if I get an answer.

I'm probably talking to myself now but it is calming.

I have just had a call from Sony, I was aksed for the same info again (3rd time) along with the IP Address of the TV, WAN address, Broadband provider, speed, mac address and router model.

I am not optomistic that this info will have any bearing but it has served to delay answering the fundamental question as to whether the TV has the capability to output DTS HDMA from client apps.

Hi Ian, The TV doesn't support DTS-HD Master Audio and Dolby TrueHD from USB files, video streaming services and broadcasts. It's written here in this article on their website https://cutt.ly/QX7i6Lc

Hi Elodin,

Thanks for your message. Much appreciated. I'm still waiting to hear from Sony themselves. They are now blaming my AVR. 😞

The link you pointed to does provide some clarity but doesn't actually answer my bottomline question. Does the TV support Dolby TrueHD or DTS HDMA when playing a locally networked (DLNA) file using a client app on the TV such as Plex or Emby for example. I wouldn't class that operation as "USB files, video streaming services and broadcasts". 

Sadly I supect it isn't supported and the manual is not specifc.

It looks as though I will be keeping my old Nvidia Shield TV (Anroid TV also) which does have this capability regardless of the source data or stream. The choice of direct codec support appears to be a political or commercial choice as specific exclusions have been applied which to my mind diminish the product. It would be interesting to know if this is the same on the Sony flagship models.

Thanks agian,

Ian

Hi ianrattew, I don't think that's supported as well. Let s know what Sony will say.
