HQPlayer4 EC modulator tips and techniques

Recommended Posts

I had the same: last week: when I changed from AL to HQP OS the fingerprint changed. Looking at ifconfig I assumed it is because HQP bridges my two Ethernet interfaces and AL does not.

That shouldn't matter, bridge is not a real network interface, but a virtual one. It is likely something else.

Ah, wonder what it could be then. My motherboard came with two stock NIC's to which I added an Intel card with two fiber NICs. Anything to do with that?

All those interfaces appear under both? At least HQPlayer OS supports also Intel 10Gbps/fiber cards. But if both don't have drivers loaded/supporting all those, then that could be one difference.

I just tested on a NUC7i7BNH, booting up Fedora 31 Workstation Live and HQPlayer OS both resulted in same hardware fingerprint, as expected.

 

Doesn't mean it always works, but within my testing that has been the case.

See below. enp1s0f0 is the only connection that is active in my case.

It is this wireless interface:

HQPlayer OS likely has driver for it, but it is possibly not loaded because the interface is not configured.

Thanks Miska. Would the solution be to configure it? If so how do I do that?

If you are not using it, it is easier and better to just remove or disable it altogether...

In that case I disable it in the BIOS?

And then apply for a new license activation from you?

Yes, check first that it disappears properly from Audiolinux. You could then also check that both give you same hardware fingerprint.

Are the storage volumes or partitions part of the HW fingerprint? I had mine suddenly change on my NUC using HQPe OS after I was installing AL onto the Optane drive which changed the partition layout. Everything else is the same hardware wise.

No, RAM, GPU or storage are not.

Seems I opened a can of worms lol

 

OK, so I'll look into why further since it should be the same.  Thanks to Bill, I have a guide to what to do.

One thing I was already wondering about was that my ip address is different with hqp os, and I have it set to a static ip at my router.

So checked router settings, and found that the mac address changed with hqp os, which doesn't make sense to me.  I'm using the motherboard ethernet jack for hqp os and buster, so not sure how it could be different.  I guess its a driver issue?

Strange then. I'm not aware of any other changes to the NUC, not even a BIOS update. What would be the appropriate email address to send the license change request to?

It all comes to me. So for example support at signalyst dot com.

Could we PLEASE take these fingerprint/licensing issues off this thread.  I realize they are important, but not at all on topic with what this thread is about; that is, a compendium of tips, techniques and experiences with the new EC modulators. 

 

If you are having HQPlayer issues then post them in the appropriate thread, thanks.  :)

I have an i7 8700 (without K or T). With HQPlayer embedded on Euphony DSD256, poly-sinc-ext2 and EC7 is not possible. DSD256 and EC5 works 'sometimes'. Of course HT and Turbo Boost are enabled. Speed is about 4.3 GHz.

With HQPlayer 4 Desktop on Windows Server 2019 in core mode on the same machine DSD256, poly-sinc-ext2 and EC7 is possible. The problem (to me) is the HQPlayer 4 Desktop is a trial version. I have purchased the embedded version.. lol. I still want to give HQPlayer embedded on Audiolinux on the same machine a try before making a decision about purchasing HQPlayer 4 Desktop and remaining with the Windows installation.

 

Update! With HQPlayer embedded on Audiolinux and also on Jussi's HQPlayer OS the upsampling on DSD256, poly-sinc-ext2 and EC7 is possible. No stutters so far but using a fanless Streacom F8 I better stay with upsampling to DSD128 (and EC7).

I was able to purchase a Ryzen 3950x today. I'll build my music server over this week/end. I'll post an update how it handles HQP upsample. 

Thank you, that would be very interesting to know whether it can handle DSD256/7EC combo.

Hello, 

 

Final pre-purchase check. 

 

I have the choice of either an i9 9900k a 9900ks or a Ryzen 3900x as a cpu to build a system around. 

 

I'm mostly putting together the build in order to use hqplayer so what are people's thoughts on which one of the three would be the 'best'?

 

Will future updates to hqplayer make the 3900x as better choice in the long run or will it always be able to make better use of a Intel cpu? 

 

Final question, any specific  considerations needed when choosing ram? 

 

As ever, all advice is welcome!

I would go for the 9900KS as long as stocks last...

 

Thanks for being specific. If I might ask, do you have specific RAM that you would recommend for use in the Gigabyte Aorus and Designare MBs that have been discussed? I recall seeing you recommend CAS and speed, but I cannot find it.

Win10 i9 9900KS/GTX1060 HQPlayer4>Win10 NAA

I would not worry to much about CAS speed. Just buy some relative cheap RAM. 8 GB is enough, but 16GB is not that expensive and is good to have if you at some point decide to use the Computer for something else.

See my recent i9-9900KS build her:
