HQPlayer Linux Desktop and HQplayer embedded

[Bertel]

Many thanks @Miska! I'm fine then, using poly-sinc-ext2 as well as Adaptive output rate (with the May being able to take 48k based DSD rate as well).

 

My DDR4-3600 CL19 modules are G.Skill SniperX Digital.

 

@StreamFidelity, the DDR4-4000 CL14 modules I was looking at are G.Skill RipJaws V (as we're both in Germany I'll link to Mindfactory here: https://www.mindfactory.de/product_info.php/32GB-G-Skill-RipJaws-V-schwarz-DDR4-4000-DIMM-CL14-Dual-Kit_1419219.html)

I have had this working before but for the life of me I can't get it to work now.

 

How do I set up HQP Embedded to accept streams from Audirvana?

If HQPlayer Embedded is functional in general, it should appear as-is in Audirvana as UPnP output device. It doesn't really need any special setup (note that I've only tested on Audirvana 3.x not on the latest).

weird, Audirvana sees it and tries to play, but nothing plays. This was on the latest 3.5 and I do not have Studio.

Any hints in HQPlayer log file? HQPlayer works standalone or from Roon? Or mConnect Player for example works?

Nothing looks obvious or out of the ordinary in the log. It works with everything else, including the HQP Client from this same Mac mini.

There should be some attempt visible from Audirvana, such as item added to playlist (queue) and attempt to play it. And maybe some failure then?

 

But you could email me log file with noted time stamps when you attempt playback from Audirvana.

 

Last time I tried it with 3.5 it worked just fine (and gapless too).

anything look wrong here?

Nothing that would make it not play. But I notice you have set fixed volume to 0 dBFS. This will trigger limiter pretty frequently. You may want to lower it down to at least -3 dBFS.

After I restart my HQPe machine and try to play to it using UPnP, playback takes a good 10-20 seconds to start. After that, playback is immediate. 
 

After reboots, all other playback is immediate though. 
 

Perhaps Doc is running into this?

Usually long delays are related to things like DNS lookup.

 

I have not seen such behavior on my testing, but OTOH, I have two caching DNS servers in the local network, etc.

I made this simple, because this isn't a mission critical location in the house, I put Ropiee on the Pi4 and solved the problem.

Quick question @Miska:

 

I use the filters from @mitchco for my SR1a headphones in the Convolution engine of HQPlayer Embedded. I think I need to set a value of 19.5 for Gain compensation (which I have done, see screenshot of log), but just to be sure: in the other screenshot from the log I see both a dB value for impulse response and for the convolution filter. Do I need to add these, or am I fine with my 19.5 value? 
 

Interestingly, and more as a side comment, when I first entered that 19.5 value I turned the volume knob on my amp waaaay down, because 19dB is a lot - but actually it doesn‘t seem to make much of a difference on actual listening volume. Must be calculated somewhere else I guess. Or am I missing something here, or doing wrong? (I also tried entering +19.5 at first before, but the + is not accepted, whereas the - is)

There are two different gain estimates calculated for convolution filters. As you can see the figures differ. But if you add some positive gain compensation, keep eye for a long time on your Limited counter that it stays 0 at all times. When it comes to correction filters, it may take long time before some 0 dB signal happens to hit some peak boost frequency. Easiest way to check your gain compensation is to play a 0 dBFS frequency sweep and keep eye on Limited counter while doing so.

Miska, I am still in the process of building a machine just to run HQP up to DSD 128 and I wonder if you have worked with the 5900X to see how much work HQP makes it do? I ask because I am evaluating ways to keep it cool with as little noise as possible. Currently I am considering the Noctua NH-P1 with one of the NF-A12x25x120 LS-PWM fan in a Meshify Compact case with no other fans. All the data I can find on the internet regarding this is evaluating the chip on all cores and in games or things like Blender and I am not sure how that would translate to use in HQP.

I have just 5800X. With ASDM7ECv2 modulator core load to DSD256 is around ~76%. With ASDM7EC something around 65%.

 

[Outlaw]

Running latest version of Ubuntu server with HQPlayer.Is there a power setting mode you can change ?

Will you be doing a load check for 7ECv2 on the Mini M1? I am hoping it will work with PS Gauss Long on my M1 Mini.

For stereo output that means such load on two cores. Load on rest of the cores depends on the filter. But for example poly-sinc-ext2 or poly-sinc-gauss-long, the load is very low.

Seems to work if you choose some other filter for Nx rates, but it is very close call with that filter.

Has this ASDM7ECv2 modulator been released in the Embedded version ??. Can't find the info on the webpage.

No, only in Pro so far. Pending for Desktop and Embedded.

Just want to let people know what I did this morning.

 

I like to test different configurations but don't want different computers. My CAPS Twenty machine has two M.2 slots on the motherboard. This enables me to boot HQP OS installed on one NVMe and Windows running HQP desktop on the other NVMe drive. This am I installed a Sabrent NVMe M.2 SSD to PCIe X16/X8/X4 Card with Aluminum Heat Sink (EC-PCIE) into an open PCIe slot with a 500GB NVMe drive. On this drive I installed Ubuntu with HQP Embedded. The system is triple boot right now. I could install another Sabrent unit for quad boot if needed. 

 

Sure, I could install HQP OS on a USB drive, but putting it on an internal NVMe drive is really nice.

 

This thing is $18 and gave me an additional really fast NVMe capable slot. I love it.
