HQ Player

[R1200CL]

Hi @Miska

Today I have an issue never happened before.

SonicTransporter with HQPlayer embedded into opticalRendu. 
 

Music playing one or three seconds then stop one second and play again. 
 

With RAAT it seems OK

 

Yesterday I enabled flow control in my Cisco Uplink port, but it was ok just after that. That’s the only change I’ve done. Made some restarts today. Don’t help. 
 

Suggestions what causes can be ?

Now after playing for 5 minutes. It seems to be gone. 
Very strange. Well anyway. Music is playing 😀

You need to have it enabled on all involved ports. So at minimum for the one where Rendu is and the one where HQPlayer is.

Hqp stopped and when I tried to boot back up...it doesn't. So I thought maybe HQP got corrupted so I uninstalled then reinstalled latest version and it still wont boot up. Help.

 

[Theobetley]

Tried going back to the previous level of Hqp...still wont boot up.

Finally, finally got a PC that can sustain ASDM7EC stutter free.  Feeding a Topping D90 using networkaudiod, it's just sublime.  👍

Any comparisons with RME ADI 2 fs, Topping D 90 and Denafrips Ares 2, in DSD  Mode?

 I read Ares can do DSD 1024.

Are they all compatible with HQ?

Letting HQ do Conversions, not the Dacs.

Did Denafrips misspell Aries...?

Do you use PCM->DSD conversion with D90? If yes, does D90 support 48k based DSD sample rates in native DSD mode, such as 48x128 = 6.144MHz (48k variant of DSD128), 12.288 (DSD256), 24.476 (DSD512) ?

Hi, I don't have any of the Dacs I mentioned, but am also interested in the answer to your question.

And i forget to mention I am on  Mac computer.

I know the ADI will get DSD 256 on Mac, but are the others limited to DSD 128 on Mac?

Will Mac get DSD 1024 at all?

The 48k flavors are typically not supported by Windows drivers.  My understanding ( @Miska  knows better than I) is that the Windows driver(s) only support the 44.1k flavors for esoteric reasons.  I have not tried the D90 on an Apple or Linux host.  I might do that at some point.

 

So yes, I'm having to resample 48k material to 44.1k.  I just use a filter that supports conversion between the sampling rate families (poly-sync-lp mostly for me).

Sweet! Please share what type of horsepower the conducive PC sports.

 

Thanks!

Interesting. Because expect of my old Gustard DAC (which supports only DoP and 48k DSD bitrates work always under DoP) I have also Topping E30 and I am using it on Windows. It has XMOS USB interface with Thesycon based ASIO drivers like the most of DACs today. It is able to play 48k based DSD content in native DSD mode if previously 48k based PCM content was played. If not, it still plays, but slower in ratio 44.1/48. Switching to DoP and back to native fixes the playback speed issue in that case. The driver Control Panel correctly displays the bitrate be it 44.1k or 48k based. I have the impression that in the E30 case the driver support for 48k based rates is here but the DAC firmware does not correctly switch between bitrate families.

 

Could you perhaps try the same based on my experience? I am curious if different Topping models behave same or differently.

I think the problem is with Topping gears or maybe drivers, as i've had various XMOS based usb diy dacs using Thesycon drivers and i've been always able to play 48k-based files on my Windows system, without any resampling and using various software players (including hqplayer, of course)...

DSD256 is maximum you can get through CoreAudio. With a Linux or Windows based NAA and suitable hardware you can get DSD1024 also from Mac, since then CoreAudio is not involved.

With Mac OS X you will have only DSD256!

I get DSD512 with Parallels and Ubuntu Studio, and I think DSD1024 is also possible with Linux!

I had DSD512 with bootcamp, ASIO and Windows 10 Pro, but latest releases go also up to DSD256...

BTW, Ubuntu Studio is the best sound OS for HQPlayer IMHO.

We are not speaking about playing 48k based PCM files without any resampling or with PCM upsampling. We are speaking about 48k based DSD rates such as 6.144MHz, 12.288MHz, 24.476MHz. You can get such DSD rates by means of PCM->DSD upsampling.

[jimdukey]

 ARES II DSD1024, PCM1536 DAC: Native DSD decoding support up to DSD1024 and PCM decoding supports up to PCM1536

 

I'm on a Mac Computer.

Will this Dac get DSD 256, 512, or 1024 on it with HQ Player?

I'm afraid I don't really know what Native DSD Decoding vs DOP means in practical terms.

It's VERY reasonably priced!

TIA!

Ares, God of War in Ancient Mythology

[jimdukey]

Well, as an Aries, I never saw that Ares spelling before this.

To me Ares is "RS".

Poor American Education?

Oh well, too late for me...

Aries is from Latin, it means "ram", as you most probably know. While Ares, name of God of War, is from ancient Greek, so the word is even earlier.

Yes, i was talking about those too. I always played them on xmos and amanero transports using windows drivers, just had problems sometimes when passing from 44.1k based frequencies to 48k based ones and vice versa, a bit like you say - that led me to think it's a usb transport related issue more than driver related...

[bogi]

Thanks. I was only surprised by your formulation

as it indicated you have 48k based files and AFAIK no one distributes 48k based DSD files. You probably converted them from PCM. :)

Just curious but wouldn't you be able to get CUDA, or equivalent functions for AMD cards via ROCm-HIP, or other libraries; it kind of sucks to be limited to NVIDIA GPU's...

That is quite close to CUDA and maybe usable. I would need to check if the library of support functions covers the needs.

 

Some support for Intel GPUs may be coming at some point too.

Miska, it's my understanding that AMD cards works better with Linux than nVidia cards do.
