HQPlayer Linux Desktop and HQplayer embedded

[Sunny_Player]

Thanks for your work Mika, everything is running smoothly now. One question: It seems, that the system's fingerprint has changed after disabling some USB-ports on my machine in the bios. Is there any chance to update the license or do I need to buy a new one?

Disabling USB ports shouldn't cause such, but some BIOS just behave strange. Changing network/BT interfaces or similar will cause fingerprint change though.

 

Send email to the support email address with new fingerprint and original key file and Aapo will update the key file for you.

 

Thank you Mika, just did so accordingly. 

 

One question: I am going to buy a JCAT Net XE. Does it bring a big improvement with hqplayer embedded or would you rather stick to standard LAN ports?

If you are using a NAA, using correct type of network cabling is more important than type of network adapter.

 

Great, thank you. What would you consider as the correct type of network cable?

[Sunny_Player]

CAT6(a) U/UTP. Preferably the 500 MHz CAT6a type, basic CAT6 is 250 MHz. CAT6a is good up to 10 Gbps.

thank you, i am using cat 7. Thinking about switching to lwl, but it has its disadvantages as well... I am not making a big fuss about cables as do not hear any difference between cables. Nevertheless, I use a melco s100 and it feels good. Does it sound better? Maybe. The biggest improvement was the hqplayer and my sdv 3100 HV. Full stop. No more cables required.

CAT7 is shielded, which is a problem, since it doesn't provide isolation that U/UTP cables do. One big reason to use network is to provide galvanic isolation. Ethernet signals are galvanically isolated by the spec. But shielded cables break this by connecting device grounds through the shield.

 

Ah, very interesting, I was not aware of that. Thank you. Currebtly, i am using viablue ethernet. Cat 7 cables with 6a connectors. Dies it fits the purpose of galvanic isolation?

Is the connector body entirely plastic (good) or metal cover (bad)?

 

ok, got your point. The body is made of 50% plastik, and 50% gold plated metal. Seems, I need another cable. Ideally a cat 7 cabel with its shield not connected to the connector bodies, right?

Dear all,

 

Just experienced an issue when changing settings in the configuration:

 

The log:

clPlayerDaemon::SetConfiguration(): clXmlElement::WriteFile(): fopen(): Permission denied

 

Any idea?

 

Thank you. 

 

 

[Sunny_Player]

Dear all,

 

From time to time, after some hours of continuously playback (settings see below, sdm mode) I experience some dropouts. Beyond that, everything is working like a charme. 

Any ideas?

Your volume is not set any higher than -3 dBFS?

 

One possible issue is that your CPU runs into thermal throttling. So I would look into CPU temperatures.

 

Any idea, which filter works better before I simply increase the fan speed?

 

Is -3 dBFS throughout fine? I am adjusting the volume directly in my preamp.

All the filters look fine, biggest challenge for CPU is to run the modulators to DSD1024 rate. That will certainly produce some heat. But just check the temperatures.

 

Just found out: These dropouts only occur with some specific 16/44.1 tracks. Very interesting...

It probably goes away if you drop output level (HQPlayer volume). There's a soft-knee limiter and re-process (find-another-solution) loop. If the find-another-solution process takes too long for example due to inter-sample overs, you may get a drop-out. Likely also the Limited counter increments (?). Limited counter should stay 0 at all times. If you stay out of this re-process cycle, you have more consistent CPU load.

 

Just checked, the limiter says 0. Currently running on-5. Should I further decrease the output volume? 

[Sunny_Player]

That should be fine then, no need to decrease output volume. It is something else then. Is there something specific to the source media that could cause delays on reading the tracks?

 

What I could identify: it is relating streaming qobuz or tidal in 16/44.1. It never happened so far from local storage. I will investigate further in this topic and let you know.

Dear all, is there any chance to get amsdm7ec2 running on a i9 13k in dsd 1024 upsampling without cuda?

A quick feedback on HQPlayer 4 Embedded 4.34.2 

 

- Core mapping is excellent for my fanless system (i9-13900K P-Cores 16 x 4GHz, E-Cores disabled).
- http://hqplayer.local:8088 works
- ssh works

 

Good job!" 👍

 

Good morning, how do you disable e cores on msi boards?

[Sunny_Player]

Since 4.34.1, hqplayer does not shut down properly anymore. Any ideas? Thank you.

@Miska

When I switch off my T+A SDV 3100 and leave my hqplayer embedded system on for a while, playback starts stuttering. Do you have any idea how to tackle that?

[Sunny_Player]

@Miskawhile applying the poly sinc gauss xl filter in sdm mode at 512 dsd and asdm7ecv2, I experience dropouts with pcm files az 88khz. Do you have any idea? Thank you. 

[Sunny_Player]

You are running out of CPU power. You could set some lighter filter for Nx rates.

 

Thank you. Yes, but why only with 88khz? 192 khz works well as well as any other sample rate.

What is the conversion ratio in each case? IOW, what does HQPlayer report as output format for each of these?

 

Thabk you, let me check later today. Is there a different filter available producing similar space with less processing power required?

@Sunny_Player You are converting 44.1x2 to 48x512. Try to set [x] Adaptive output rate - that will convert to 44.1x512.

You mean, i shall disable 48 dsd?

[Sunny_Player]

42 minutes ago, bogi said:

Adaptive output rate means that 44.1k based sources will play at 44.1k based DSD rates and 48k based sources will play at 48k based DSD rates. It does not disable 48k DSD but it adapts to source rate family. Just try it, it will help or not.

Ah, you mean "auto rate family"? I have enabled this already. 

[Sunny_Player]

It looks like you don't have set it:

88200 = 2 x 44100

24576000 = 512 x 48000

Ok, thanks for the hint. Seems I have misunderstood something in the settings of hqplayer: So i have family rate enabled, birate set to 24576000 and rate limit to 49152000. What settings do i have to make when i want to upsample to dsd 512?

Just now, stefano_mbp said:

Leave Bit rate to Auto and set Rate limit to 24576000, other settings are ok

Brulliant, thank you, I will give it a try tonight.
