@Tfive - that's why I said in my previous post "you are right". Me neither can hear any resampling artefacts and your argumentation already convinced me in 100%
When the time allows (weekend most probably) I will make fresh install of Ubuntu 20.04 LTS and install your soft to try. Certainly I will back to you afterwards with tones of questions :) :)
One of the first question cross my mind is how to use equaliser together with the crossover (to equalise bandwidth between 20Hz to around 40Hz where my cabinets got already -3dB drop down)

Tfive 7th July 2020 06:58 PM

First of all you might want to stay away from 20.04 as it seems to have a premature pa version bundled and it seems to have problems with ladspa plugins. Might want to try 19.04 instead. Or Linux Mint, my Dimension for desktop use.

Secondly you can also insert as many eq blocks as you like into your crossover chain, for example on at the very beginning before splitting signals. That way you can modify the overall sound of the chain. No need to use the separate eq program at the same time.

@Tfive - so your software is similar in concept - various "blocks" (I know not the same - just to imagine principle) like Windows VST Host, correct? With that differance it is limited only to filters and EQ. Regarding Ubuntu - I want to stay with this distribution as I am most fluent in that (never used other distribution actually and start my journey with Ubuntu 8.04 many years ago :) ) But thank you for advice - I will go with 19.04 then.

Tfive 7th July 2020 07:24 PM

Yes, it's probably similar to vst host.

And Linux mint is based on Ubuntu. So all the base things are almost identical. If you're finally feed up with Ubuntu you might look into mint's direction. ;) if not, PaXoverRack should run just fine on Ubuntu too.

@Tfive - regarding distribution: let me ask the question other way round - did you use Mint to develop the software? The reason of that question is following: since Kodi Media Center interface is full-screen type one can't see what system sits below anyway so it is completely irrelevant for me which distribution will I use. BUT from functional point of view it makes the biggest sense to stick to the exactly the same distribution as software was originally developed in/for - in other words to the distribution you are using.

Tfive 7th July 2020 08:16 PM

Yes i used mint to develop. But under the hood Ubuntu and mint should be so similar that no problems should arise. I also regularly test on other apt based distros. They all worked fine except the one with problems, Ubuntu 20.04.

BTW I also run mint and Kodi on my htpc. I read some questions about kodi a few posts back, so to summarise: kodi will use the crossover just fine as PaXoverRack will set it's input sink as default sink.

@Tfive - sounds that's exactly I need :) But I prefere to go with Mint then as if I will potentially need any support from you it will be easiest for you if we "speak the same language" - having the same system distribution :)

@Tfive As I didn't installed your software yet I can't check myself so I would like to ask you: will it work with 3x stereo PCM2706 INSTEAD multichannel card? In total we have 6 channels but from 3 USB devices. For testing purposes I made set which is USB hub and 3 times cheap Chinese PCM2706 card. See pictureAttachment 859108

How do you intend to synchronize the 3x2 channels (same start, same clock)?

Well, I see no reason for syncing. But perhaps I miss something so please clarify. I mean we stream via USB digital data simultaneously to identical devices with identical latency so what is the potential problem?
