  1. Now there are updated NAA images for RPi3, RPi4 and x64. I think the previous RPi image also had ASIX driver, but at least this new one has.

    You need two if both are running simultaneously. Just one if only one is running at a time.

    Since NAA, or any other HQPlayer output is not visible to Roon, it cannot be switched from Roon. If you have two HQPlayer instances, then you can switch from Roon, since these are two distinct outputs for Roon.

    No, if it works, no reason to worry. I think only glitch is that Windows is not displaying GPU loads accurately, but nvidia-smi will give a definitive answer. You can compare how much nvidia-smi diverges from the figures shown by Windows. They should be the same, but it may not be the case.

    OK, good, this shows HQPlayer being active for CUDA (C for compute, C+G for graphics and possibly compute too). Memory usage and loads look normal. For the case where GPU temp hangs around 59 degrees, the "GPU-Util" figure is likely also higher.
  6. This is very much system dependent. For my UpBoard and UpSquared I'm using Meanwell's medical grade PSU: https://www.meanwell-web.com/en-gb/ac-dc-medical-desktop-adaptor-output-5vdc-at-6a-ac-gsm60b05--p1j For my CL100 I'm using a Mascot PSU: https://www.mascot.no/catalog/power-supplies/acdc/desktop/230v/9320/c-24/c-1318/p-122 If you like something better, take a look at Teddy Pardo PSUs, you get those with various different power connectors. I use inexpensive ones with a ferrite bead. This can significantly reduce amount of RF

    Looks good, I just think the Windows GPU load figure is not showing everything. If you start "nvidia-smi -l 10" on command prompt and check there what it says about the load?

    The GPU load figure looks so low, that does CUDA come enabled (see status bar message when starting playback)? I'm getting 40% GPU load on RTX2080 for the same case...

    That's only for Windows, I made a build for macOS too, available here instead.

    Just partially different implementation for some algorithms like FIR, IIR, convolution, sinc- filters etc. Should be compared to 4.7.1 since these are otherwise the same. Could be better, same or worse in performance. What I've tested it doesn't make big difference in performance. So going forward this is what upcoming releases would have.

    In preparation for some new future hardware support, there's now experimental build with alternative optimizations for various algorithms, available here. Otherwise, apart from some small bug fixes it is essentially same as 4.7.1.
  12. There's no SSH because it is not very useful and for security reasons because it would be bad idea with a default password. OTOH, drivers need to be built specifically for the kernel they are being loaded on, so you cannot download a driver from another kernel. In addition, many distributions for RasPi are 32-bit, while my OS images are completely 64-bit. This would make anything built for a 32-bit OS version not work.

    You need driver version 450.51 or newer for CUDA to work on 4.7.x.

    Any number of NAAs you may need are covered by the license of HQPlayer using it. Any number of HQPlayer Clients needed to control HQPlayer are covered by the license of HQPlayer being controlled. So essentially you need licenses for the number of HQPlayer Desktop or Embedded (server) instances running. Control applications from other parties have their own license terms.

    These two are typical simple silence patterns. In latest HQPlayer Desktop you can enable this from settings. When it comes from a modulator it should look pretty different without a recognizable pattern, because the two first ones encode a high frequency tone. Transformer is a different case, my original implementation uses 4th order Sallen-Key active analog low-pass filter and cable capacitance compensated output buffer. If you need to be close to hear the noise, it is low level, but it is still ntermodulation leakage from somewhere. DSD256 with ASDM7EC sho
