  1. I am running a dual boot system for HQ Player Desktop using Windows 11 and Ubuntu 22.04. My music is stored on a separate internal drive from the OS drive. This is a Samsung NVME drive that is formatted NTFS. HQ Player Windows Desktop works fine in recognizing the music library correctly. However, under HQ Player Linux desktop, the album art is lost after each reboot. I must rescan the library to fix the problem. Miska believes that this is related to the music drive being formatted NTFS, and the lack of perfect compatibility between Linux and NTFS drives. Before I reformat the drive to exFAT, has anyone else experienced this problem - and found a workaround that does not involve reformatting?
  2. Hi Miska, Thank you. What is the identifier for for the EFI partition related to the boot loader? Should this be done within Windows disk management?
  3. I have installed Ubuntu/HQ Player Linux Desktop on a dual boot system with Windows 11. HQ Player Linux Desktop resides on an external USB drive that contains an Intel M10 SSD. I would like to install Ubuntu/HQ Player Desktop on my main C drive instead. The partition has been created on the C drive for this install. Will I run into a problem with the boot manager after the install? My plan is to disconnect the USB drive. My concern is that the dual boot system already exists and is pointing to the USB drive. Will this be a problem for the Ubuntu installation on the local C drive?
  4. I was able to install HQ Player on a minimal install of Ubuntu 22.04. I installed the low latency kernel as you recommended and deleted the swap file. This all fit on an external 16GB Intel M10 Optane NVME drive plugged into a USB C 3.1 carrier. I used the Optane M10 for its low latency performance. The system shows 4.2GB of free space on this minimal install of Ubuntu. As I am new to Linux, installation involved a bit of playing bumper car with the brain - but all was eventually sorted. Thanks to everyone for their advice.
  5. Below is a pic of the inside of the PC. Case is a ZZAW C6. The processor is an I7-11700K, CPU cooler is Noctua-U9S with push pull Noctua fans. Motherboard is an Asus Z590M. The video card is Nvidea RTX-A4000 (which replaces the ASUS Hyper M2 PCIE silver card (that was previously installed). The remaining cards are an EVGA Nu Audio card capable of DSD 256 output, Matrix Element H USB card, and Asus Thunderbolt 4 card. The power supply is a Corsair SFX450. 128GB of Crucial RAM is installed. An Optane 480GB SSD contains the OS. Two Samsung 980 Pro 2TB NVME cards are used for music storage. There are two top-mounted Noctua 120mm exhaust fans. Each fan has a different blade pitch to better distribute the noise profile. All fans are run on DC and not PWM. I post this here in response to your inquiry. I hope it helps. That said, we should ideally return to Nvidea GPU discussion.
  6. The need to upsample to DSD256 (as opposed to DSD512) makes your task easier. I was able to upsample to DSD256 with poly filters using only the I7-11700k without GPU. Doubling the upsampling rate to DSD512 will effectively double the total compute power required. I am personally not a fan of the sinc-L filter. It is an integer filter, which means that to upsample 48kHz PCM to DSD,, your DAC must handle 48x DSD. Most DACs including mine do not have this capability. When using sinc-L to upsample PCM to higher rate PCM, I found it to be an analytical sounding filter that presents great precision in the reproduction of detail - but is leaner in presentation than I'd like. If I was to build a new PC, I would wait a few months for the release of Intel's new Meteor Lake CPU's and matching Z790 motherboards. An Intel I7-13700k is probably all that you need (without a GPU) for DSD256 upsampling. This chip may very well handle DSD512 by itself. Having some margin with your selection will be a good thing for the future. You can find early benchmarks for the I7-13700k by using a search engine. If I needed to add a GPU, I can't speak highly enough for the RTX-A4000. It draws very little power so that my total system power consumption hovers around 300 watts. The small fan and single slot size makes for a hot running card with slightly higher noise than would be ideal, but overall it is a great choice for HQ Player. Hope this helps.
  7. Thank you for these replies. HQ Player desktop on Linux is the least painful entry for learning. I certainly am not yet ready for an embedded install. I'll give desktop a try and see how it goes.
  8. I am currently running the trial version of HQ Player desktop under Windows 11 Pro. I am considering testing the Linux desktop version as well and have some questions. 1. Can you run Windows desktop and Linux desktop on the same machine using one license key? 2. Is the minimal installation of Ubuntu 22.04 Desktop adequate for the HQ Player desktop install? 3. If so, will the minimal version of Ubuntu Desktop install comfortably within 16GB of storage space? 4. Are there benefits from a performance or sound standpoint to the Linux desktop vs. Windows desktop installation? I have zero experience with Linux, so a desktop installation would be an appropriate starting point.
  9. I recently purchased an RTX A4000 video card to pair with my I7-11700k CPU. I am now able to upsample Qobuz files to DSD 512 using ASDM7-512 fs as well as ASDM7ECv2 modulators with filters such as poly-sinc-ext3 or poly-sinc gauss-xla. CPU utilization runs just over 40% and GPU utilization also maxes out at 40%. (Note that GPU utilization is measured by Asus GPU Tweak 3 software as Windows task manager yields incorrect GPU measurements.) Total system power consumption remains comfortably under the 450 watt power supply used for the build. Needless to say, I am pleased with my choice and would like to thank Rovo for this recommendation. Here is a chart that shows a number of graphics cards, both classic and current, and some relevant specifications: Graphics Card FP64 performance Memory Size (GB) Memory Bandwidth (GB/s) GTX 1060 137 6 192 RTX 3060 199 12 360 Quadro P5000 277 16 288 RTX 3070 317 8 448 RTX 3080 465 10 760 RTX 3090 556 24 936 RTX A4000 599 16 448 RTX 3090ti 625 24 1008 RTX A5000 868 24 768 Explanation: HQ Player uses 64 bit floating precision to perform its computationally intensive task of up-sampling. The reason why this is important is that Nvidea’s pipeline for its Pro cards typically offers twice the bandwidth for FP64 processing in comparison to its consumer graphics cards. This 2X multiplier is a conscious decision on the part of NVidea to differentiate their pro line from their consumer line of graphics cards. This Pro series advantage can make a noticeable difference in the power needed to run HQ Player effectively. If you look at the above table, you can see the strong performance of the RTX A4000 graphics card. For playing games, the RTX A4000 is considered to be the rough equivalent to an RTX 3070. Reviews confirm this performance bracket for gaming. However, for HQ Player, the RTX A4000 slots in closer to the RTX 3090/RTX 3090ti. Total memory available is also important if you plan on upsampling to DSD 512 with demanding filters such as sinc-L. I hope this information proves useful to others in making their choice of GPU. Finally, as Miska points out, CPU power is needed for the modulator, so your CPU and GPU should reflect a balanced choice depending upon your goals.
  10. Thank you very much for this input. I am now considering purchasing the RTX A4000 video card. How loud is the A4000 fan at idle? How loud does it get when under the load of DSD512 processing? Have you ever measured the GPU temperature?
  11. I would like to choose a GPU that can help up-sample to DSD512 using sinc-L. For the RTX3000 series, is 12GB sufficient? I recognize that many factors are involved as well. I would like to make sure that I understand the minimum need. In the conversation, it was mentioned that 16GB may also be required for sinc-L. depending upon the GPU generation.
  12. I have been able to test DSD512 playback using Windows kernel streaming. It works as a proof of concept - but still has the same dropout problems as DSD256 kernel streaming. I am testing a Singxer SU-2 DDC which allows for DSD1024 input over USB. This makes DSD512 kernel streaming possible.
  13. 1.1 still stopped before the end of the track in testing last night. There were also multiple dropouts. I had experienced these problems in 3.5 during the prior month. It may be that using kernel streaming exacerbates the problem. With regard to kernel streaming, test the output by selecting device maximum frequency in upsampling as well. I was able to use kernel streaming at 32bit/768kHz PCM. If this also shows a problem, then AS is not recognizing the sampling capability of your DAC.
  14. My favorite = Kernel streaming + DSD256 Upsamplling + R8Brain + Min Phase + B8 Modulator
  15. I just played Bill Evans; Live at Shelley's Manne-Hole from High Definition Tape Transfers at DSD256 using kernel streaming. It worked fine. But - the AS software was just upgraded to rev 1.1. I had not tried this test of an actual DSD file on the 1.0 release.
