DSD multichannel file play through DLNA Renderer problem

--- Quote from: wer on February 18, 2021, 07:26:45 pm ---That's not a valid assumption. There are lots of receivers that do multichannel DSD when they can directly open the file (like on a USB stick or NAS) but not via DLNA; they're restricted to 2-channel only via DLNA. For example, the results you described above are exactly the results you'd get from a Marantz receiver or processor.

Ok, maybe OPPO also has those kind of restrictions. However according to your explanation on below, JRiver will send "FILE" if I do not convert anything.
--- Quote from: wer on February 18, 2021, 07:26:45 pm ---Moreover, if you haven't configured any conversion into the DLNA server, it is not sending a bitstream, it is sending the file. If the file is multichannel, the Oppo gets a multichannel file. What it does with that file is up to the Oppo.

When I get file from my network disk through SMB protocol, it plays mutichannel without any problem. So USB stick is out of question.
If JRiver send just "File" as you explain, it should be same "File" which I get via SMB protocol, right?
Then it will play multichannel without problem, too. That I don't understand...
As you can see "whoareyou" post, OPPO 205 can play multichannel via DLNA. 203 has exactly same capabilities like 205...

The audio section is different from 203, but I thought 203 / 205 support same audio formats over network. Does manual say 203 supports this (I did not check manual)?
205 only shortcoming for me was lack of gapless playback over DLNA. Otherwise plays everything over network flawlessly.

I found a site that said different Oppo models supported different formats. The 205 supported the most. But that site was silent on this exact issue.
https://help.nativedsd.com/en/articles/94445-playing-dsd-on-oppo-machines-explained
But it did say this:
--- Quote ---"The Oppo 203 will play DSD64 Stereo and Multichannel, and also DSD128 Stereo as maximum, and only from a USB storage drive connected to the unit. "
--- End quote ---
Not very well written.
So again, I suggest contacting Oppo to be sure, rather than spending a lot of time chasing something that might not exist.

So try the following:
Turn off the bitstreaming (does DoP even support multichannel?), You just need to send the file to the Oppo. If I remember correctly, bitstreaming is not the correct setting for this and you should not be sending DoP.
First try seting format to "original" and make no output changes. See if that works. Again, I'm not positive, but I thought the 203 supports pretty much any format out there.
Most likely, no need to convert anything to / from a different format unless you know there is something that Oppo does not support.
PS - This was from a windows machine. Not sure if there is difference with Linux.
Good luck

Thanks for your confirmation that 205 can play multichannel audio via DLNA but not gapless playback.
I don't think that gapless playback is possible because JRiver send each file to file when play is start. So there need time to send and receive through network, so gapless play is impossible (that I believe because of this flow).
Yes, 203 / 205 has same capabilities for play "file" no matter it is came from USB stick or External Drive or Network Drive through SMB.
According to wer, 203 must play multichannel through DLNA / HDMI if JRiver is sending "File" to OPPO.

I think my speculation is correct, Anything looks or logically wrong, please pointing me out. ;)
wer:
Vcast, again, you're making assumptions based on the belief that if it does one thing it must do another, and that it must be the same as the 205.
The first part is demonstrably false, whether you understand or not. The second part, I don't know about, and you don't know either: you're presuming.
If you won't contact Oppo to confirm, and you're sure you're right, then you should not have any trouble at all finding posts somewhere of someone saying they've done multichannel DSD via DLNA on the 203.
Or even better, since you seem to be saying it's an MC problem, you should not have any trouble getting it to work straightaway with another DLNA server like bubbleupnp.
If you can prove that it works on the 203 but just not with MC, then hopefully JRiver will address it.
Your "according to wer" is wrong. You didn't understand. I said the Oppo would receive a multichannel file, not that it could play it.
The 203 and 205 are different. They have different DACs. For example, the 205 supports MQA, the 203 does not. I suggest you find out if this is another difference.
Good luck.

All right, I will say something in fact.
My oppo can play DSD64 stereo and multichannel via USB stick and network drive.
Network drive is linux or window base, doesn’t matter. I now did and enjoy it.
Only 205 and 203 different is DSD128. I don’t use DSD128 for test.
So, I not chasing anything which is you said that might not exist.
But my investigation through google said that OPPO 203 also Roon ready, and can’t play multichannel DSD through Roon. They are looking for which part is block the playing multichannel DSD and now oppo is out of this business.
Nobody can answer which part has problem, so I just use oppo media app to play multichannel DSD from my network drive, it is no problem.
But I don’t want use 2 different app for enjoy music, that is why I post this question at first hand. If I don’t use JRiver Remote app and only use OPPO media app, I have no problem at all both stereo and multichannel DSD file through network.
One more thing I need to add:
My OPPO 203 has no internal DAC board. I use Vanity24HD which is capable of send stereo/multichannel DSD format to External DAC with DoP encapsulation through Coaxial cable. It can decode all kind of DSD file. So my 203 capability is not same level of 205.
Actually DSD format will not send any DSD format to external DAC but only through HDMI. It is limitations for all device which is copyright restrictions. Vanity203HD is break this limitations and do the thing way around to archive play DSD file through external DAC.
