CPU load is still double that of DSD 128 just like prior version.

 

That's how it should be. The algorithm scales linearly, so every time you double the sampling rate, the load doubles.

I can report that I can get the asdm5ec modulator -> dsd256 to work, with version 4.1.1.1, CUDA offload set to convolution only and multicore DSP set to fully enabled. I have a Ryzen Threadripper 1950 with SMT disabled, so 16 real cores only and overclocked to 4 GHz.

CPU cooling is very much under control and everything else is up to date, latest Win10 and latest Nvidia drivers, latest BIOS etc.

 

If I enable full CUDA offload for instance, I get stuttering. Multicore DSP to auto is not helping me either. The configuration in the first paragraph seems to be the best for my hardware and one of the new modulators. Asdm7ec -> dsd256 will still stutter though.

Thanks for your explanation, if possible I would like to try your special Debian 4.11.2 version with this extra optimization.

 

There's now build 36 for Debian and build 32 for Fedora that puts back that optimization that I removed recently. It also syncs some other small tunings from Desktop.

I understand, I didn't express my point well....what I intended to convey was that the there is no evident improvement in cpu efficiency running ASM7EC with 4.111 versus prior version. The cpu utilization is the same as with 4.11.

OK, yes, that's the case. These optimizations are around work load distribution to different CPU cores. 4.1.0 -> 4.1.1 there was one change for multicore enabled case where modulator CPU efficiency got improved at least on my Intel CPUs. Same algorithm, but just different data access pattern.

I am not getting connectivity from the microrendu to the dac. in mysonicorbiter I go to dac diagnostics and it shows no dac connected. I tried rebooting the microrendu, tried shutting down the dac and restarting but nothing seems to work. I even pulled the power plug from the rendu and then reinserted. Would appreciate some guidance. I am using Hqplay

[guiltyboxswapper]

On a 6800k mildly OC'd to 4ghz, with a 1080 GTX I can run ASDM7EC @ DSD256 rates with poly-sinc-short-mp.

I'm curious given the years of focus on fanless PC's.  How many currently OC'ing to make EC work did so previously? 

 

Or for that matter how many are silently watching until sense returns to the discussion.

Some people use 
Roon > hqplayer 4 > networkaudiod 
?

I have problems with the track change, the play stops

This does not happen with hqplayer 3

What does HQPlayer say as a reason in the log file?

Given how quiet a fan cooled PC can be, and that one can use a NAA to move the PC out of the room if necessary, I'm not even trying to build more fanless PCs.

 

But maybe some of the fanless PCs work? Streacom DB4 could accommodate for example i9-9900K.

I forgot, where is the log file in linux?

It is in "~/.hqplayer" directory a file called HQPlayer4Desktop.log

 

If you are upsampling to DSD, one somewhat likely reason is that

1) You have "Adaptive output rate" checked and

2) You don't have "48k DSD" checked (most DACs don't support this) and

3) Content you are switching to is 48k-base rate

 

Recommended settings:

1) Do not check "48k DSD"

2) Set DSD rate limit to suitable 44.1k base, for example "44.1k x256"

3) Set "Adaptive output rate" to unchecked on grayed

This is very embarrassing. Unbeknownst to me I had  a power failure in which case my LIO reverts automatically  to an analogue input rather than the digital input. Thanks to all who responded. Problem now fixed.

Problem is here:

! 2019/09/10 19:28:26 clHQPlayerEngine::Execute(): clStreamReaderHTTP::Read(): read timeout
 

Roon is not providing data and HQPlayer times out.

 

Other than that, playback doesn't exactly match with those settings. Playback is at DSD128 while output mode in settings is set to "[source]". So output mode is being switched externally.

I'd like some clarification about the Min/Max Vol Setting for upsampling to DSD 128.

I've been using -3Min/-3Max for a long time, as per recommendation from Miska.

I've seen -60 Min/0 Max recommended, but I get no sound at all that way.

Does -6 Min/0 Max provide the same clipping protection as -3 Min/-3 Max?

It is my understanding that the Min/Max are the setting for the volume control knob on the main HQP Desktop console. If you are not hearing anything, then check the position of the knob.

 

I have my settings at Min = -60 and Max = -3 for which I keep the volume control knob turned all the way up (clockwise) which translates into a -3 setting for which I believe Miska usually recommends. In my case the Min = -60 is a bit arbitrary given I don't adjust volume using the volume control knob.

 

You can achieve the same thing by having Min = -6 and Max = 0 and have the volume control knob set at the 12 o'clock position which translates into -3.

yes, changed from source to sdm from hplayer4client.

 

so it's a roon problem?

but with hqplayer3 it works well....

 

in fact the scroll bar in roon, with hqp3 it moves with hqp4 no, probably there is an error just at the recognition of the lengths of the tracks

Yes, it is either Roon or network problem. Maybe more to do with slow internet connection or server. Version 3 has the same timeout. Both wait for 10 seconds and if there's no data coming in 10 seconds it gives up waiting. You could try if you can reproduce the same problem with local content.

 

For me, the playback position indicator works with v4. Roon doesn't know how to control most of HQPlayer things, so check that you have position indicator set to "Time" in HQPlayer.

 

 

P.S. I have not seen such problems with Roon using local content or Tidal. I cannot test Qobuz because the service is not available in Finland.

Good news for Ryzen 3000 systems.

https://community.amd.com/community/gaming/blog/2019/09/10/ryzen-community-update-bios-updates-for-boost-and-idle-plus-a-new-sdk

 

Please remind me, has anyone successfully run the EC modulators at DSD256 on a Ryzen 3700X or similar?  The upcoming BIOS update should help.

Cuda Off-load

 

I am running HQ Player on a PC running Windows Server 2016.  Nvidia is saying that there are no drivers for the Geforce RTX Series 20 products for the Windows Server OS.  How are others using a graphics card for cuda off-load while running a windows server OS?  Do I not need a driver since I am not using it for video?  Will the Windows 10 driver work even though they are saying it isn't supported?

 

Any guidance here would be appreciated.

The Windows 10 driver should work. It did for me with an Nvidia GTX card.

yes, the problem was the "Time" set to Remain
