Got it. miniDSP used to use SRC4382 for the SPDIF/AES receiver and ASRC. It can do upsampling to as high as 192kHz. May as well since it is doing ASRC anyway. (Benchmark uses the lower distortion SRC4392 in DAC-3.)
Suppose you could take a SPDIF output from the miniDSP and run it into a PC sound card SPDIF input. If you display the spectrum in Arta (free version) you might see some difference in an FFT depending on where upsampling is done. Probably work best if you used something like a 1kHz test tone record as the source. If you have a variable speed turntable, you might even be able to get the test tone to line up with an FFT bin, who knows.

Oh total heresy, but once I had decided on a digital crossover I had to embrace it fully. I hope eventually to have something to offend most of the audio tribes out there in my system 🙂
Yes, my daughter hops in my car, plugs her phone into the AUX port for the car audio system, and calls up one of her playlists. She probably picks one she knows Dad will like, so next thing I know I'm hearing Nina Simone covering Janis Ian. I didn't even know that existed, because I play albums and I don't have any Nina Simone albums. I must get some.
Likely correct. I have no specific knowledge here, but based on many years of windows driver experience, I would try uninstalling then reinstalling the jplay driver. As you say, some windows update has probably shuffled/re-ordered a driver stack such that jplay now doesn't exist.
PS: At work recently another group did an in-place upgrade of their Windows Server operating system on their hosts, which not only broke the application my team supports, it completely removed it.
One other consideration is how well each resampler handles changes in incoming sample rate. I know my miniDSP nanoAVR does a rather inelegant job of this at times, with several snaps & pops at the start of a new file with a different rate.
In defense of the miniDSP stuff, my setup also uses HDMI audio (gasp!), so there's probably some stupid copy-protection reneg adding to the confusion at times like this. But whatever the cause, to reduce the new-sample-rate blues, I just use Foobar to resample everything to 96K, even though the miniDSP box is doing exactly the same thing (gasp!). Foobar isn't perfect at handling these changes either, but seems to handle them better; and the nanoAVR is certainly a lot happier seeing a constant 96K incoming rate.
Just for clarity (or perhaps pedantry), the resampling test here would not be "miniDSP vs Foobar" but rather "miniDSP vs (Foobar + miniDSP)".

Geez pages and pages of things like this is exactly why I gave up on PC use for music app.
I depend on DAC engineers (specialists) to have worked out the interface issues for me and make recommendation best for their product and go with it.
I just spent money on JPLAY and never got a key code sent to me. Another hick-up/burp. I used to laugh at these things....😡
Now, its just a stupid waste of my time (and money).

I just looked at the Jplay web site. They have morphed into a full range of stuff with impossible claims and questionable value. However it must be working for them. Still $4K euros for a 5 port ethernet switch with a 1M packet per second throughput switch? An entry level Dell does 10X that but doesn't have incompatible connectors. Maybe there is an opportunity here. . .
I would never use JPLAY. There is nothing wrong with Foobar2000 or any other halfway decent media player.
Is the Jplay playbook typical?
You start out with one particular thing for a particular niche and happen to do well with it - then, you " morph into a full range of stuff with impossible claims and questionable value".

IF I ever get time I should be able to compare linux upsampling on a straight file vs what comes out of the USB-SPDIF converter vs what comes out of miniDSP set flat then the same chain but miniDSP upsamping.
As there are free multitone samples out there that might be a good candidate.
I don't expect any huge epiphany of course. I have other boogeymen in my system.
Once again. If you are streaming or have a load of music on a server then seriously look at Roon. It's a few hundred $$$ for a perpetual licence but does work well and apparantly is very good for huge collections.
Bill from what I gather it’s best to have a dedicated server for Roon running Linux with hq player.....and it must have a fast/powerful processor, which comes at a premium!$!
Given the target market and the relatively low cost of a fast PC I don't see that as an issue. All depends on size of music collection. If you have 20,000 albums on the server you need an i7. Now an i7 NUC with memory and SSD will be $600-700 Roon is $700 for the perpetual licence. So $1200 ish all in. Some people spend more than that on an interconnect!
The reason for the fast processor is so it s can x-ref all your music and streaming sources to give you a value added view onto your music. Depends how much that is worth to you.
Not everyone has huge music collections, in which case this will not be for them. Others have great memories and know where all their music is. Some like fiddling with computers to save money (me).

It's true, other than the driver it looks like a bunch of smoke and mirror BS...twas ever thus in the consumer audio world...glad to have spent my work life on the professional side of the tracks where there is much less of that tripe. Of course it had it's own problems, usually related to some nonsense an artist approaches the studio with, but in general work was driven by results and performance, not hype.
Cheers,
