HQPlayer Embedded thread

Yes this is what I do - works fantastically well

Its not a USB B that feeds the UpBoard - it’s a micro B OTG port

Same cable type that comes with external hard drives normally

You can run Embedded on the UpBoard but it will be limited to PCM upsampling

What I do is use the UpBoard as an NAA input for my more powerful 11900K HQP Embedded server which is in a different room

How do you feed the DAC? Care to draw the whole chain?

Do you mean this one?

Normal way HQPlayer can output to any DAC - ALSA or NAA backends, can be either.

The UpBoard in my case is only part of HQP “Input”, like a Roon input or UPnP input.

But if you are happy with light PCM filters you can just run Embedded on the UpBoard itself I guess. And connect with USB cable to DAC.

Is that mean you are running two HQPlayer, one at upboard another one at 11900K HQP embedded server? How can you feed from the upboard to the server?

On UpBoard it is running NAA OS which features support for UAC2 input

Then this outputs over the network to HQPlayer Embedded (UAC2 NAA input).

After that it is normal process - you output to USB DAC or NAA endpoint

Thanks, one more question. Where to set HQPlayer embedded to receive NAA input?

Yes, there’s a link from my web page too, under “Recommended hardware”.

Product page is here:

May need to edit the config .xml file, especially if have other NAA’s on the network

I can share instructions here if you get the UpBoard

Are you already using Embedded?

Yes I am running embedded on a Ubuntu

And USB DAC is ALSA connected or you are using NAA? Which NAA?

USB DAC can connect to my Mac or RopieeeXL.

Ok so you would need to possibly rename the UpBoard input NAA.

With NAA OS it comes with default name “naa” and you can’t have multiple NAA’s with same name.

So I renamed mine to “UPBOARD” and then make Embedded config xml file point to this UPBOARD NAA for network input

I can share all the details if you order it.

It’s just changing a few lines in .xml files

Hi @jussi_laako

With amd build and without GPU support, can your i9-12900K do 8 x channels @ DSD256 output?

With 2-channel PCM48k music to 8-channel DSD256x44.1k output

gauss-long filter (I would assume gauss-xla can’t be done?)


One thing to note (I have discussed it a few times in this thread) is that I have issues with UpBoard UAC2 input, if I set HQP output to auto family rate

With my RME ADI-2 DAC

If I fix HQP output to DSD256x44.1k, I have no issues at all.

I thought latest NAA OS solved this but doesn’t.

Not a big deal really, for me.

Weird question: Every time I update my HQP OS Server USB stick I get a different IP address on my network. I’ve set my router previously to issue a static IP address for this device but the HQP OS update still gets assigned a new IP. Wondering why this is. Is there some trick to keeping the same IP?

It is because of the virtual interface involved. If Roon would use latest API then there wouldn’t be need to worry about IPs. But if your network is suitable, and Roon uses DNS for the address, using “hqplayer.local” as address should work.

Hi dabassgoesboomboom,
Tried your criteria except 8ch source on my i9 12900k but unfortunately it would stutter w/o GPU. Have to enable the CUDA offload to get good result (as you can see the loading was fairly heavy on my 3080TI 12GB, and very heavy on all p-cores). Although gauss-xla + 7ecv2 was a doable combo but I personally would use low loading filters and modulators like 5EC for 8ch DSD upsampling. Linux kernel stabilities matters (I met at least 3 times “soft lockup” when using heavy EC modulators more than an hour listening. FYI.

This part I quoted - is it only an issue with 8 channel output?

Or you see instabilities with 2 channel output also (with ASDM7ECv2) ?

And is it do-able with auto family rate enabled? Assuming your 8 channel DAC supports both x44.1k and x48k rates.

Without GPU
