You need Network Audio Endpoint software on the NUC.

 

Thank you, can you point me on how to get that software

[AudioDoctor]

If your NUC is running Windows:

If it is running Linux then go here and choose which version of linux you're using and get the right one:

Or you can boot, from USB, to Jussi's own HQP OS and have a dedicated NAA image.  Simply burn to USB via something like etcher, then boot to USB and you're done.  Most NUCs I've done that on work great.   I'm trying another NUC as we speak.  That one I've successfully installed the NAA on top of Linux Mint, but wlll try again the option with Jussi's image too.

 

The NAA idea is to galvanically isolate the dac, isolate the server from getting its noise to the dac (theoretically then allowing you to have a noisy server, sitting in another room).  It allows for lightweight processing (although more powerful NUCs, a slight oxymoron, seem to sound the best), dedicated processing, and in some cases allowing the dac to perform better than the server's own OS will allow  (for example, a Linux NAA NUC being served by HQPlayer on a Mac Mini and processing higher sample rates than the Mac OS can natively handle)

I downloaded the networkaudio-411 and ran it, it opened a command prompt when I choose networkaudioadapter on either input or output device setting, there is nothing drop down on the device drop down menu.

 what is Jussi's HQP OS sorry I am a newb.

 

I have a NUC i3 running WIN10 connected to a HOLO May DAC and an I7 Desktop with gtx 2060 super I want to use for HQPlayer. thanks for the suggestion

[AudioDoctor]

This is the embedded OS. I have never used it.

Is your device connected and powered on?

[Blur510]

yes everything is powered on right now.

[AudioDoctor]

Which machine is your screenshot from? It should be the desktop machine running HQPlayer.

[AudioDoctor]

I have never used HQPlayer in this way, I use a Sonore device and raspberry Pi4s that run the NAA image so I can only guess at this point. Tomorrow someone will likely be able to give you better answers.

this is from my desktop running hqplayer.  roon core is also running on the nuc.  Thanks I will buy a raspberry pi and run the NAA image if I have to but I want to try to get this to work first. thank you so much for all the help.

Roon Core and the NAA can NOT be on the NUC. it's one or the other. Delete Roon from the NUC and put it on the desktop.

[ted_b]

The NUC (or wherever you have the NAA) should have the Holo ASIO driver (if Windows) loaded on it.  If using Linux (like Jussi's image) then no driver needs to be installed; Linux will take care of it.   And set dac bits to 20 on HQplayer settings (May is linear to 20 bits).  The NAA machine should have little else installed on it.

 

Roon core could be on your desktop, along with HQPlayer...but that is a compromise.  Roon is very talkative and HQPlayer does not like that, so your sq will increase if you find another nuc to put Roon on.  But that can be done down the road.

Is there any actual drawback to using GPU instead of CPU?

 

No, only if the GPU is slower than the CPU, then it can make things not work (CPU ends up waiting for GPU to complete it's work).

 

If you have a fast GPU, you can move part of the work off the CPU. This can help the CPU reach higher turbo clocks because fewer cores are under heavy load.

Will the actual resulting data output differ in any manner?

 

No...

Is there a tutorial on how to set up roon and hqplayer?  I want to use my NUC > DAC as my endpoint.  I have a Desktop that I want to use as a  rooncore and Hqplayer.  I can play music on my NUC > DAC, but no HQPlayer upsampling.  I can play music on my desktop (Roon + HQPlayer. thank you

Thanks. 

I wasn't sure if floating point precision or something would mean that the result would be different.

Do you upsample to DSD256 with NS5?

 

Because my HQPlayer doesn't upsample to DSD256 with NS5, if your do, I'd like to know how...

 

No. Yours is working as intended.

Is there an advised baseline config for Rockna DACs?  HQPlayer running on Mac mini M1 to Zen Stream NAA (and maybe ultrarendu) to Wavelight.

Both cases use same IEEE 64-bit floating point for the applicable processing parts. Theoretically there could be minor rounding differences in some places due to slightly varying algorithm implementations (one way or the other, not straightforward which one would be more precise). But given the possible output resolutions to the DAC, those are not applicable to real output data, even less so in analog output signal from the DAC.

I'd start with the same as for Holo Audio. Until there are linearity measurements it is hard to come up with other numbers.

I've actually got a wavedream signature coming in soon so should be able to get some info on that.

Those look like linear to about 17-bit. So safest to get started with "DAC Bits" set to 16 or 17.

 

Then the linearization settings would be better confirmed through measurements. I use 1 kHz sine at -120 dBFS for that purpose.

Are there sonic or measurable improvements having CPU cores set to a fixed frequency vs. variable--less jitter?

No, it will just cause performance problems for you and increase power consumption. CPU clock and audio clocks are not related.

 

[TheTalbotHound]

Curious to know how the Apod counter on HQplayer works. What sort of thing does it look for in a file to make the counter go up?

[Mops911]

@Miska, now that I belong to the family officially - I just purchased my license - may I ask, if and when HQP can stream Qobuz directly? 

Thank you
