Got that while streaming from Audirvana to HQPe. Sender is sending too small pieces at once or very slowly. It is sanity check that HQPlayer doesn't end up burning a lot of CPU time busy-looping on the network receive function, so it gives up trying to get enough data fast enough. Is that A+ on macOS? Because I have never seen that before on A+ context. Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

I have not tried that myself, only the macOS version that has been around for a while. Is that happening frequently? Is it related to a streaming service like Tidal or local file playback?

Streaming of Qobuz. It happened twice last night. I will try local files later today. Link to comment

arglebargle Posted October 14, 2018 Share Posted October 14, 2018 @Miska could you give a brief explanation of narrow vs wide SDM-SDM conversion setting? Link to comment
asdf1000 Posted October 14, 2018 Share Posted October 14, 2018 Hi Jussi @Miska We discussed a few months ago the possibility of seeing the current HQPe volume on the ‘’main’ page. I see more features being added to this main page. Are you still planning to show this current volume? Maybe even a volume adjuster? Roon can show the exact dB of HQPe but BubbleUPnP and mConnect and Audirvana don’t - these only show a volume %. I thought maybe the ‘’main’ page can show the current volume in dB like Roon does? If one could adjust from this page that would be a great bonus but even just a display of current would be great. Love all the HQPe updates you are releasing. Many thanks Link to comment

UPnP devices cannot show the volume in dB due to how volume is represented in UPnP specification... arglebargle and asdf1000 2 Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

Especially when converting down from higher SDM rate to a lower one, some small amount of bandwidth limiting happens. With "narrow" the ultrasonic response rolls of gently a bit more than with "wide". I couldn't decide to stick with just either one of the two designs, they have their sides. So I decided to make both available and give option to choose. I had hard time figuring out how to call this, but you sort of select between two remodulator frequency response curves. P.S.

Popular Post hifi25nl Posted October 15, 2018 Popular Post Share Posted October 15, 2018 With version 4.6.0-4 archlinux/audiolinux package (really is PKGBUILD file in arch) is perfectly equivalent to bionic package. if you start it with systemctl start hqplayerd It will also create user hqplayer etc. As in older version there is also the possibility of starting as user with systemctl --user start hqplayerd https://aur.archlinux.org/packages/hqplayer-embedded/ arglebargle and simonklp 2 AudioLinux --> https://www.audio-linux.com developer of AudioLinux realtime OS Link to comment
arglebargle Posted October 16, 2018 Share Posted October 16, 2018 @Miska Thanks for the new help section -- the perfect amount of information all in one place. Would you say SDM -> SDM upsampling is slightly heavier now with wide/narrow algorithms? Link to comment

shadowlight Posted October 18, 2018 Share Posted October 18, 2018 @Miska if I had option to pickup a new system and the cpu choice was e5-2643v2 v/s i7-6700, which one would you recommend? I am leaning towards the Xeon due to slight faster CPU speed with 2 additional cores + 25MB Cache, but wanted to get your opinion on it. Link to comment

But I would possibly go for the Xeon, although it is quite old Ivy Bridge generation.... Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

Let's see how well it handles 44.1k to 48kx512DSD on it's own ?. The server will reside outside of the listening room connected via gigabit switch connection and wireless on the NAA side. Edit: If it does not work out well, I can always use it as a VMWare server. Link to comment
shadowlight Posted October 19, 2018 Share Posted October 19, 2018 Is it possible to use multiple nVidia cards (K2000 in my case) and do you get additional benefits with it? Link to comment

Yes and no, at the moment I don't have code that would explicitly use multiple cards (possible, but just not there yet). But the Nvidia framework could be still doing something about it... Nobody has reported back what happens, and I don't have any machine yet with more than one card. Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

I will give it a shot in about 2 weeks when I will have a chance to install Ubuntu on the system. I am using Debian right now. Link to comment
clang Posted October 22, 2018 Share Posted October 22, 2018 I am planning to buy a new 8th generation Intel NUC to try HQPlayer Embedded and would like to get some answers first. 1. My DAC, Mytek Brooklyn, is limited to DSD256 so I'm not going for DSD512. Would the quad-core i5 be adequate? Or would an i7 always out-perform the i5 in SQ? 2. I see that people go for 19v in their power supplies while the technical spec says that 12-19v are supported. Would 15v or even 12v do the job? Or again, would the higher voltage out-perform the lower ones? 3. When I click to download the HQPe image, I get a list including : "images", "stretch" and "Xenial". Which one should I get? Thanks in advance. Clarence Link to comment

Although I don't have any 8th gen NUCs yet, for -2s filters to DSD256, quad-core i5 should be just fine. With i7 you get usually around 10% performance gain at matching clock speeds. So the clock frequency difference plus 10%. Usually not a big difference. 9 hours ago, clang said: 2.

"bionic" is packages for Ubuntu 18.04 Bionic Beaver, "xenial" is packages for Ubuntu 16.04 Xenial Xerus (now outdated) and "stretch" is packages for Debian 9 "Stretch". Then there are "fcXX" for corresponding Fedora releases (only fc25 and fc28 maintained at the moment). asdf1000 1 Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

Hi @clangthe specs are accurate. I've been using a 12V LPS for months and not only does it work without issue, the sound appreciably improves using it over the supplied PSU. Link to comment
