  1. Please check that you don't have same output device enabled in both Roon and HQPlayer. Any error messages shown on HQPlayer status bar when things fail? HQPlayer log file could also tell what is going wrong. You can find details on how to find the log file in Troubleshooting -section of HQPlayer manual.

    Not as far as I know, since I don't think any virtual machines emulate device side USB. No, because HQPlayer wants to be as close to the hardware as possible, which is exact opposite of containers.

    Yes, best way to do it is to use HQPlayer Embedded and then feed it from a Windows computer using S/PDIF, AES/EBU or USB. By using something like ADI-2 Pro as input device it also works nicely for analog sources as well. Note however, that it is not useful together with video.
  4. Yes, because they generally lack device side USB hardware support. They just miss the needed hardware...
  5. Type of physical interface is not relevant from my point of view. That depends on the actual hardware... There are bunch of embedded SoMs that can do it.
  6. Remeber to check the case measures for maximum cooler size! NH-D15 is pretty massive. If you are connecting DAC directly, one alternative is Z490 VISION D which has DAC-UP2 USB ports.
  7. Either HQPlayer OS or NAA OS image for example running on normal PC hardware...

    I see this answered already to some extent... Net result is the same whether delays are adjusted in convolution filters or the channel setup. For stereo, usually the channel delay adjustment is not necessary because listening setup is fairly symmetric. For multichannel it matters a lot because you have also rear (and maybe side) channels. If all distances are equal, the adjustment is not needed (zero delta). If you go towards higher word lengths, it is not a problem. You pretty much get zero-padding. If it would be going towards lower wor
  9. Either image should work... HQPlayer OS has a bit more frequent updates. Only thing to look at is to avoid conflicting hostnames that would mean you have more than one NAA with same name. Unless you explicitly define some other name through /etc/default/networkaudiod This is wrong, this is local one, but you are not having your 9900K connected to MacBook via USB. Yes, you need to add new input item that refers to your NAA and the USB audio behind it. Here's example line from Desktop input configuration: <input address="naa" channel
  10. Good news is that Apple has today shipped my Mac Mini with M1 and it is supposed to arrive by Dec 7th. So it will come earlier than expected. I have some amount of ARM code already since HQPlayer Embedded is already shipping for 64-bit ARM platforms like RasPi4 and NXP's i.MX 8M. Apple has some annoying shortcomings in their Xcode tool set though that add some extra challenges in some areas.

    All available filters can do that if you enable 48k DSD and set "Adaptive output rate" to checked. But only limited set of filters can convert 48k PCM rates to 44.1k based DSD rates (multiples of 2.8M). Possible conversion ratios for each filter are listed in Desktop manual and in Embedded help page.

    Yes, I have one around. At DSD256 you can choose between ASDM5EC and ASDM7EC. Objectively lowest out of band noise is with ASDM5EC, but I've been running ASDM7EC which gives theoretically best audio band. Filter is up to your choice. I personally have three which I switch between. poly-sinc-ext2 as primary, and poly-sinc-short-mp and sinc-S as alternatives. If some recording sounds too harsh or too much "on your face" and/or with sibilance, poly-sinc-short-mp is good fix. If poly-sinc-ext2 sounds too smooth/soft, then sinc-S is good alternative. For example with hires version of Da
  13. That is HQPlayer? It should be disabled or left alone on default settings (null device). NAA doesn't have any settings interface... This is fine as long as the two NAA's have a different host name. Inputs are defined in <input> section of hqplayerd.xml Note you have two backends, one for input side and another one for output side. One can be local (ALSA) or remote (NAA). Then as device selection you have hostname:device tuple. (note, NAA just defaults to hostname if nothing else is defined, you could define somethin

    I changed the pipeline gains to -3 dB and been now jumping around the tracks of couple of albums without limits. It is not so clear from the graphs what is maximum sum gains of the two responses. Maybe I'll split the frequency and phase response to separate plots in future version.

    And by the way, please check that you don't have anything you don't want at Convolution engine side. On 4.8 version these two were split completely, and you can now have both active at the same time for different purposes. But there were some configuration file migration features for a while...
