Sonore - Audirvana Plus 3.1 Output Mode

Agreed for sure!  I am a bit confused at this point, as I always thought Macs/A+ only output DSD via DoP...

 

@mansr, @damien78: can A+ output native DSD (without DoP) (when streaming over Ethernet), to a suitable renderer and DAC?

Sorry, can't help with that. I don't even own a (modern) Mac.

.... the mystery remains murky ...

There is no mystery as fas as I know:) When you place the Rendu in MPD/DLNA output mode and check that it supports native DSD that is what it's expecting. A+ arranges for whatever resampling rate you set in it's preferences and afterwards it presents a URL to the Rendu for that stream. The Rendu then takes that stream (either PCM or DSD) and it outputs to your device via the appropriate format which are all listed in DAC Diagnostics. In the case of DSD it uses the native DSD driver built into Linux if your DAC supports it. As an example the resulting rate of 88.2 in DAC Diagnostics is what is used for DSD64.

Jesus, this makes no sense to me?  If we are talking about native DSD, to the DAC, what does 88.2 KHz have to do with it?

solve for r:

DSD64 = 44.1 x 64 = 2822.4 

2822.4 = r x 32

There are no bits (i.e. 32) in a native DSD stream, not sure what you are saying here.  Sure R=88.2 in your equation, but if we are sending native DSD (1) to a DAC, it should be a sample rate of 2.8224 MHz, or 2822.4 kHz (as you wrote).  Is this just some way linux looks at DSD?

It's just another way to transmit the data over USB. All that matters is that it's bit perfect DSD to your DAC. Again your DAC has to support it and if not you need to use DoP.

Yes - I mentioned I was doing this earlier (well the system I bought for my old man, my dad). Native DSD256 to an ultraRendu to an iFi iDAC2

Am I right that this question has nothing to do with Sonore?

So we can move further discussion to the Audirvana 3.1 thread in the software section.

disagree: this is about how A+ and the Rendu products work together in delivering DSD, especially native DSD and high rate DSD, to a DAC, at least that is what I am trying to understand.

is there now a definitive answer whether native DSD (not DoP) is possible via Ethernet?

Thanks

So, this check box under MPD/DLNA settings should be checked if you use mac os & A+? - what does it do in regard to A+?

 

“ This will enable Direct DSD to your DAC instead of DoP. Your DAC must support Direct DSD to use this feature.”

There was never any doubt in my mind:) In fact, if you use the MPD/DLNA output mode you can also send native DSD to a micro/ultraRendu via a Mac running MinimServer, JRiver, Roon, or HQ player. LMS can also do it, but you need a certain version and or a special plug-in to do it.

I'm having no luck getting A+ 3.2 to work with my MR. Unlike Roon, which was pretty much a flawless install, A+ routinely crashes, fails to output music to the MR, and seems to have difficulty syncing to my libraries. Running High Sierra and SonicOrbiter 2.5. It has worked -- and sounds great when it does -- but will not work consistently. Grateful for any tips from the community here.

 

best,

Did you update to the latest version, AFAIK 3.2.3?

Hi Matt,

 

Thanks for the reply. I have indeed. Roon working perfectly. No dice (again) for A+ 3.2.x

[matthias]

^^^Put your question in the Audirvana 3.1 thread in the Software section (or at the Audirvana Facebook site) too. Maybe Damien can fix the problem.

Thanks, M -- will do!

Well, months into 3.1 ... there’s been no fix for A+ into ultraRendu - & Roon works perfectly all the while. Done the round of support access.

I'm sorry it's not working for you. To be clear A+ does work on the ultraRendu. Maybe best to send it in for service so we can rule out the unit itself.  

[vortecjr]

I wanted to let everyone know that there is now a firmware update available that will allow you to use A+ with a Sonore Rendu (i2s/SPDIF) unit and Sonore Signature Rendu (i2s/SPDIF) unit. If you have one of these and want to give it a try email me at [email protected] for the procedure.

[Jamesroy]

With a MR attached I now have no access in pref's to change DSD over PCM and no access to Direct Mode. Using A+. How do I get the same choices using MR?  I'm using SOX filter. Thanks

[vortecjr]

What version SonicOrbiter are you running and have you pressed update recently? What DAC are you using? Post a screen shoot of the A+ configuration screen.  

[barrows]

@Jamesroy:

 

Are you talking about Audirvana preferences?  For DoP streaming settings you need to use the sonicorbiter web interface, not A+ preferences when you are streaming (Ethernet) via A+.

 

As for Direct Mode, I am not sure that even applies when streaming via A+, that would be, a question for @damien78.

 

Note that the available settings and preferences for A+ are a little different when streaming by Ethernet vs. playing direct out.

[Jamesroy]

Thanks for the reply.
