Hi, I am using MC27 master license, Both windows and Linux.
My Windows MC 27 is connected to Emotiva RMC-1 Processor via HDMI 2.0 through nVidia GTX 1065.
Here is what I got:

OPPO 203 - play SACD Disc or DSD file - HDMI - Processor shows it is DSD stream. Stereo and Multichannel. No Problem.
PC - Windows 10 - MC27 - DSD file (.dsf) - GTX 1065 - HDMI 2.0 - Processor only got PCM Stereo and Multichannel.

My PC acknowledge that my Processor as 24bit/192KHz capable multichannel device. Using WASAPI type output.
No conversion whatsoever on DSP and Device setup menu.
No bitstream is checked. So my processor aware it is PCM. Unlikely my OPPO 203.

Ok, when I check "Bitstream DSD" option on DSP menu and play DSD file, no playback is start. No sound, No play, nothing.

How can I send "Native DSD format stream" to my Processor? Is it possible?
Some infomation said nVidia is not possible to send DSD stream through HDMI, but I don't think so. Graphics card does not have any role on this process, it just "pass through" bitstream to processor, since there is no DSD to PCM convertion circuit is existed on Graphics card. Any idea?

Unfortunately it's not possible. GPUs and onboard graphics from Nvidia, AMD and Intel or whatever on the devices handles the HDMI video output would have to support DSD in their drivers, and they don't. Thus it's not possible to play DSD over HDMI from any sort of computer whether it's a PC, Mac, Raspberry Pi, etc.

DSD over HDMI only works for devices like SACD disc players connected via HDMI to a receiver, for example.

Oh my goodness... so it is graphic card which prevent DSD bitstreaming...?? That is so bad.... I did try ASIO4ALL driver, but also it does not work. Thanks for your infomation.

[Awesome Donkey]

ASIO4ALL won't do anything (and in general it's not recommended to even use, as it's just a wrapper for Kernel Streaming, a legacy audio component of Windows, and is not actually ASIO), the issue is on the hardware/driver level.

One can send DSD to the Oppo via LAN/DLNA and use the Oppo's HDMI output to send DSD to the Emotiva.

Yes, what you describe is exactly what I am doing for listen DSD file from my shared folder on Windows PC.
OPPO can pull files from PC with SMB protocol, I can use OPPO Media Control App which is really pain in the a** because it's UI and functionality is under mediocre level. OPPO can pull DSD file from DLNA Server(JRiver), or JRiver can push DSD stream to OPPO, both can play DSD file but not DSD stream but only PCM. OPPO is discontinued, and there is ONLY SOLUTION for play DSD file with DSD stream enabled on Emotiva or other brand processors(I have Onkyo PR-RZ5100 as well). I did investigate a lot possibilities but none is worked except using OPPO and SMB protocol. I have to take good care of my OPPO.... 

[kr4]

If that does not work for you, let me suggest that you connect your PC to the Oppo via HDMI and use HDMI outout of the Oppo.

So right.

[vcastceo]

Since PC HDMI out is not capable of send DSD bitstream to Processor, even if I connect PC HDMI to HDMI IN (Audio Only) OPPO, it does not help anything, isn't it? Also I can't see screen. That is major problem.  ?

[vcastceo]

So right.

Yes, still there is no products like OPPO 203/205 which have various multi-fucntionality, I must keep it clean.
Moreover I have special DoP modification on my OPPO, so I can send native DSD(DoP) signal to my DAC via Digital Coxial.
There is no such product which has this kind of funtions(Actually it is prevented by Copyright limitation for SACD).

On mine, the mechanical drive module failed. I tried cleaning and oiling the parts, but without success. However I was able to buy a replacement Sony module online.

A problem.  Not a major one.

Oh, this is looks like OPPO Clone player for sure. I never seen it before.
Digital connectors location on rear panel such as LAN, HDMI, Coax, Toslink are exactly same as OPPO 203.
There is not much info on this web page, but probably it is one of OPPO-base with advanced analog PCBs included.
Thanks for your info!

*********

Sorry, this is Pioneer LX500/800 base model. All exactly same.
It does not possible send DSD(DoP) through Coaxial Digital. I am using OPPO 203 because of this feature and only reason. Of course normal OPPO also no way to do it but with VanityHD (discontinued) or OPPOMOD DoP board can do it. (http://www.oppomod.com/)
Play DSD directly with Hifi DAC (I am using Chord DAVE now) is awesome and fantastic.

[vcastceo]

Yes, it does.
A problem.  Not a major one.

Wow, Thanks for your kind post, Kr4.
Is these are actual photo from your setup?
PC -> JRiver -> Graphics HDMI out -> OPPO HDMI In?
If you connect like this, JRiver can send DSD stream to OPPO via HDMI?? How possible?

If JRiver can send Native DSD stream to OPPO through HDMI as you show me, why not to Processor? Am I missing something??

[Awesome Donkey]

Correct, you can't.

I'm pretty sure Kal was talking about bitstreaming DSD from the PC to the Oppo via LAN/DLNA using DSD-over-DLNA (DoPE) in his first reply.

https://wiki.jriver.com/index.php/DSD#DSD_Over_DLNA

I'm going to gander a guess and say in his follow up replies that maybe he was referring to disabling DSD bitstreaming and upon trying to playback DSD material letting Media Center convert it to PCM on-the-fly and sending that to the Oppo? I could be wrong with what he's trying to convey, but that's pretty much the other alternative besides DSD-over-DLNA.

It's already been explained that the graphics device handling the HDMI output on the computer whether it be a PC, Mac, Raspberry Pi, NUC, etc. does not support DSD in the drivers. Nvidia doesn't support DSD, AMD doesn't support DSD, Intel doesn't support DSD, Apple doesn't support DSD, Mesa (open-source Linux video driver) doesn't support DSD, etc. When connecting a device like a SACD disc player directly over HDMI to an Oppo or Marantz receiver for example, it's not an issue as there's no computer with an operating system and drivers along with a GPU controlling the HDMI output/input on both devices, it's a direct connection between them. That's why DSD over HDMI only works with that kind of thing, not from any sort of computer.

Those pix were from my library and I am no longer at the house where this stuff lives.  When I get back, I will re-cable to confirm/recant what I said. In about a week.

[vcastceo]

Yes, that is what I did now, and it is only solution for Play DSD without HDMI connection, but DLNA is not possible to send multichannel DSD (It is probably only OPPO's problem, I don't know other brands).

Hopefully, you can double check and confirm that your setup is correct and works.

Andrew, Could you please share the link where I can buy Sony's OPPO 203 laser pickup replacement module?? I would like to buy for spare parts in case of fail, but I only find pickups on eBay, all are not original but "compatible" parts. Yours is original parts from Sony, right? Let me know where I can buy. Thanks in advance!!!

That's not so.  I am playing multichannel DSD right now from my PC-based server with JRiver/DLNA to my Oppo 105 via ethernet.  I do not have an AVR/prepro here in NY so I must use the Oppo's analog outputs.

Yes, I found that JRiver DLNA setup -> DLNA Server setup -> Advanced -> uncheck DSD bitstream(DoPE renderer) option and now I can see DSD signal on my OPPO with DLNA connection. However I haven’t check HDMI from PC to OPPO yet, I will test it tomorrow. Hope it works.
And moreover, with DLAN connection with OPPO, DSD Stereo and multichannel both works nicely now! I was struggling to get multichannel DSD through DLNA long time but no luck, many people said that it is OPPO which does not accept multichannel DSD with DLNA. But it is now! Only I uncheck bitstream option and finally it worked. I don’t need SMB connection any more.

By unchecking the DSD (DoPE) option, you send DSD at its native sample rate, which is what the Oppo and other players recognize.   This option causes a lot of confusion. An additional  Bistream DSD (Native Sample Rate) DLNA option would be nice to have. It would be a lot more obvious than the current situation.

True. I did check it because it looks like use native DSD bitstream but PCM format DoP signal (I was not pay attention what is DoPE renderer mean). It need to edit name for more clear meaning or add another option as you explain.
