HQPlayer Embedded Discussion [2021-2022]

Thanks for testing. See if it remains in 3.2GHz even under the load. That is what happens in my system.

In your Ubuntu server, was it a fresh install? I am having trouble playing 192khz content, upsampled to DSD, through roon on my ubunter server 22.04 fresh installed.

Chunhao_Lee · June 7, 2022, 1:36pm

In my observation it’s roughly 135w when idle for HQPOS and 90w for Jammy + HQPe. So it matters.

Yes and runs HQPe only. 192 → EC → 1024fs works smoothly.

Jose_Vita · June 7, 2022, 2:07pm

Thanks again. It remains a mystery to me why I can’t make it work. Maybe Jussi can help debug.

Just one more info, if you allow me: are you using the standard low latency Ubuntu server kernel or the Jussi’s custom one?

Chunhao_Lee · June 7, 2022, 2:21pm

My last re-install was using Jussi’s custom kernel. Both worked great on my system.

Jose_Vita · June 7, 2022, 7:09pm

Thanks! I will try later this week with jussi’s kernel

Embedded should work on Linux Mint right? I tried a few images, but couldnt get it to work the other day, which one should I go for?

dabassgoesboomboom · June 10, 2022, 12:18am

Oops, missed your earlier post.

Linux Mint is still on Focal. Not yet on Jammy

All Versions - Linux Mint

For Linux Mint use this one, which is not being updated any more:

https://www.signalyst.eu/bins/hqplayerd/focal/hqplayerd_4.32.0-134amd_amd64.deb

If you need to use Desktop right now, use Ubuntu Desktop?

And then you can use latest Jammy which is the main now:

Thanks @dabassgoesboomboom. I can’t remember what I tried last weekend, it was probably an error on my behalf, but will try again tomorrow.

FYI - default CPU-freq governor on HQPlayer OS for rPI is set to “powersave”; because of that my CPUs refuse to run faster than 600 MHz, no matter the load; after manually setting it to “ondemand” i was able to upsample to 768k PCM without issues, using any of the following 2 filter combinations:

poly-sinc-gauss-long / poly-sinc-gauss-hires-lp / LNS15
poly-sinc-ext2 / poly-sinc-short-lp / LNS15 or TPDF

edit: if anyone has a similar issue - you can force CPUfreq governor at boot, by adding kernel parameter “cpufreq.default_governor=ondemand” to file /boot/cmdline.txt

No go with custom kernel. Funny thing is I installed 22.04 desktop. Hqplayer desktop will run as expected. Should I run embedded from this same desktop install, I cannot get DSD from 192khz material.

Jussi,

I can no longer get sound from HQPlayer. I’m using an OpticalRendu as NAA and an Ayre QX-5 DAC. The rendu diagnostic shows the Ayre DAC is connected. I can run Roon just fine. But I noticed this in the HQPlayer Config screen:

After multiple reboots of both devices I can sometimes get the Ayre to appear in the NAA section, but even then, I get halts and dropouts. Jesus says the OpticalRendu is working fine. Any ideas?

jussi_laako · June 22, 2022, 2:03am

You have the DAC enabled in Roon as output zone? You cannot have the same device enabled in both applications at the same time.

Ultrarunner · June 22, 2022, 2:30am

HQPlayer is the Zone selected in Roon. It used to work (but with the occasional dropout). I was just pointing out that if I change the Zone to Roon Ready everything works fine.

So the rendu recognizes the DAC properly, and I can play Roon without HQPlayer. But when I switch to playing from Roon to HQPlayer, I no longer get sound and I assume it is because of the Device disappearing from NAA in HQPlayer. It used to appear.

Chunhao_Lee · June 22, 2022, 5:17am

Disable the rendu in Roon’s audio setup before you play thru HQPlayer…

jussi_laako · June 22, 2022, 11:28am

If a zone is enabled in Roon’s audio settings, it will block HQPlayer, even if it is not the active zone. So you need to disable all zones you want to use through HQPlayer in Roon’s audio settings.

See last paragraph here:

Ultrarunner · June 22, 2022, 7:27pm

Thanks guys. That solved it. Now I’m back to the occasional halts/dropouts that seem to have no solution. I’ll have to consider HQPlayer money down the drain. At least Roon plays completely reliably.

Chunhao_Lee · June 22, 2022, 11:33pm

What’s your system spec?

dabassgoesboomboom · June 22, 2022, 11:52pm

There’s always a solution !

How is everything connected together.

What are all the devices and how are they networked together?

Could be CPU limitation but could also easily be networking

IgorSki · June 22, 2022, 11:52pm

Are dropouts related to all type of play back or they are reate/source specific, like PCM or DSD?

HQPlayer DSD reproduction with certain parameters may be times and times heavier than ROON, can’t really compare.

just my 5ct…

EDIT: Another thought may be relevant. If I read QX-5 DAC specs correctly, it does
on USB: 44.1, 48, 88.2, 96, 176.4, 192, 352.8, 384 kHz / DSD64/D128 (as DoP)
on Optical/SPDIF/AESEBU: 44.1, 48, 88.2, 96, 176.4, 192 kHz / DSD64 (as DoP)

Looking at your screen above, I’m not entirely sure HQP settings are correct? I may be wrong…

Ultrarunner · June 23, 2022, 12:02am

Roon Core and HQPlayer Embedded reside on a SonicTransporter i9 Optical. The STi9 status usually shows about 25% average CPU average load with current settings. At the other end is an OpticalRendu, running the HQPlayer NAA. This sits behind a USB-connected DAC (Ayre QX-5). The DAC accepts up to DSD8x. I’m running DSD4x. I’ve tried a different DAC, but still get the dropouts. The dropouts don’t seem to be related to format type or resolution of the source file. I’ll try reducing the output resolution to DSD2x and see if that shows anything.
