It is rather simple.
If you have Roon Core configured to make use of HQPlayer, then HQplayer has this configured in its internal configuration (it is developped/programmed this way)
If you would like to use HQPlayer Desktop/client to play a track, HQplayer will not be able to do so since it believes(/knows) that it should be used with Roon Core.
I don’t know technically how exactly it is done, so the only way to make sure that this is not bothering, is to make sure that HQplayer is not used by any program, before configuring the program that you want to make use of it.
Therefore, my advice to try to ‘deconfigure’ HQplayer in Roon Core, make sure that the OS is restarted compeltely so there is no register values kept/cached, and start from zero again.
Perfect, Dirk! Thanks a lot. You explained quite clearly that the proper way to go is via Roon Core and I‘ll do so. HQPlayer generates an incredibly smooth SQ in my system, so I‘ll stick with it.
One final question: does the signal path look OK? For the moment, I am not upsampling, however, I forgot in the HQPlayer settings to remove dithering.
Signal path looks fine, but I am sure that playing around with the different settings availlable in HQPlayer, further optimization of Music quality is achievable.
It dpends first of all of your own taste, the music your are listening to, and the processor power available to HQPlayer.
I myself , am burnt (burned ?) in to DSD, as I have been listening to SACD quite a lot, before computer audio really took off.

Alas, DSD is not so good in my system. I once tried it, my Devialet goes only to DSD64 (if I‘m not mistaken), it sounded terribly veiled. But of course, I have to experiment a lot with the HQPlayer’s PCM upsampling possibilities. It will take time to tweak. But what I am hearing now, without upsampling, is truly good!
Do I understand this correct: you cannot run HQ player on a Roon Nucleus or Intel NUC based Roon rock server as they are both running on Linux and to use HQ player you need either Windows or Mac OS (on the same computer).
You are correct that you cannot run HQ Player on ROCK or a Nucleus. The ROCK OS is a Linux based specialised OS that runs Roon Server only.
You are incorrect that HQ Player requires Mac OS or Windows. It will run on Linux, either Desktop or Embedded.
You can run both Roon Server and HQ Player on a machine running full Linux. I do this on a music server in another room. You can install Ubuntu or another Linux on a NUC (instead of ROCK) and run both (results depend on power of NUC). Rugby has linked to commands to do this.
What sort of setup would be optimal from an audiophile standpoint in terms of running Rock and HQPlayer. Here are some examples:
Roon ROCK on an Intel NUC with fanless Akasa case, LPS powered and w/Ethernet cable to audiophile switch in listening room + HQPlayer on M1 MacMini (not dedicated) in listening room but with Wifi connection to the network.
Intel NUC as above running Ubuntu Linux with Roon Core server and HQPlayer on same PC w/LPS.
Intel NUC above running ROCK as in 1. above plus another Intel NUC running HQPlayer etherneted to the same audiophile network switch.
Any other configuration suggestions you may have for optimal Roon HQPlayer interaction with the least EMI and best SQ?
I am currently running Roon ROCK on a NUC10 i7 32 GB RAM and 250 GB M.2 SSD as in example 1. above. Thanks very much.
I have an Intel NUC (fanless) that runs Roon only, with ethernet cable to network switch . I have HQPlayer running on a spare Windows 10 PC that I have, but that is wireless. Would the Windows PC benefit from also being connected by ethernet, or would it be pretty much similar performance wise to wireless?
Thanks
Just a technical question. Let’s say I’ve got a PC that carries my music library and hosts roon server + HQPlayer.
should I move roon server to another computer (with ROCK), and keeping all other things equal, when I play a file, would roon server go fetch the file on my PC (the same that hosts HQPlayer), and then transmits it back to that same PC to be played by HQPlayer, or would HQPlayer directly access the PC storage, avoiding this back and forth?
