When installing ...are you getting several security alerts to be generated in Windows 10 ... "blocked program" ... you need to: check "Windows Security"
 
"Allow an App through Controlled folder access"
 
check the: "Recently blocked apps" ---> if you noticed a Security pop-up during the Software's install
 
Handy step by step how to:   Add or Remove Allowed Apps for Controlled Folder Access
 
 

Have you installed all the Gigabyte drivers/utilities for the motherboard, including the USB 3.1 ASMedia driver?  Have you tried disabling the onboard audio in the motherboard BIOS?

Is it something to do with "Disconnect the device and reconnect it" at the end of the set up wizard? Like what am I supposed to be doing there?

Now this might sound really bizarre — but you may actually have to power off your PC, remove the power cord / flip the PSU switch, open up your case, remove the card, reboot, and then repeat but this time put the card in again. That might actually work. My understanding from talking with an EVGA tech on the phone is that may need to be done in some circumstances, but he was not sure if it was still the case, and if so, what the exact circumstances are.

So I tried the full shut down, no help there sadly. Then I took did a full shut down, flipped the PSU switch on my power supply, removed the cable, then completely removed the card, powered the system back on, turned it off after everything loaded up, put the card back into the same PCI-E slot (x1), then powered it back on and tried to do the install, still the same thing as usual. So I completed the whole thing again but putting the card into the PCI-E x8 slot this time, still the same "disconnect the device and reconnect it later" thing. Could it be something with sound device manager, every time I do this I have nothing selected for audio cause all my options are on-board audio or my monitor. I will not try my PCI-E x4 cause it shares with my M.2 SSD and I kinda need that thing and my x16 has my graphics card which I would like to stay there. The pre-install of the driver always works, and it doesn't seem like the card is dead, the RGB works perfectly and I can hear it click on when ever I turn on the system.

I'm having the same issue. I can't seem to get the drivers installed. I just purchased the new Nu card Tuesday. I contacted EVGA and they suggested I RMA the new card.
I haven't received the new card, but it seems to me this is some sort of software issue?

New drivers are going up today.  I'd suggest giving those a shot first.

i end up returning it.... try doing  it for 3 hours nothing came out
the installation fall all the time 
I don't recoomend  it

I purchased the NU audio card and received it yesterday. I've spent over 3 hours trying to get the software to work. I've read the threads in this forum. I've loaded software many times. Ive tried to load the software, turn off the computer, remove the card, power up the computer, turn it off install the card turn power back on - nothing has worked. I've noticed thee is a long time frame from the last update on this subject. I also noticed the software has been updated. I can only load whats is on the website. I've tried both the Nu audio drivers and the NU audio pro drivers - same issue both times. I'm still looking for the answer but running out of patients. What may cause this issue and what are the options to resolve it? I see no security pop-ups nothing stopping the download so where is the issue.
Thank for any help thats out there

I am reviving an thread from June, but I would like to add myself to the list of people unable to get version 0.2.1.14 of the Nu Audio software to work, which would be driver 4.66.0
 
I bought a Nu Audio card on August 5, and installed it some time around August 13. It was a B-Stock card. The software and drivers installed on first try, and windows recognized the device as an output audio device.
 
 
I used the sound card every day to power some headphones from then until September 18, (~1 month), when suddenly it did not appear as a playback device in Windows, and I could not find it in device manager. The little icon for the Nu Audio on my system tray was not there, but the process was still running in the background. The executable  C:\Program Files (x86)\EVGA\NU Audio Card\NUA.exe would not run.
 
I tried rerunning the installer that I had saved (I store all my installers.), but it would not install, because it could not open NUA.exe for writing. I then uninstalled stalled the old version of the software and made sure that the [C:\Program Files (x86)\EVGA\NU Audio Card] and [C:\Program Files\EVGA\NU Audio Driver] were deleted. I then tried to reinstall the drivers but I eventually got the the two messages commonly brought up. One is that I need to physically unplug the device and plug it back in (PCIe slot mind you), and the other is "Evga Nu audio driver failed to install correctly" and then asks me to reboot and rerun the installer. (I did not screenshot the exact wording of these.)
 
I tried this, and did not work. I then tried downloading a fresh copy of the installer and it did not work. I then tried running the installer with the card unplugged, which did not work of course. I tried shutting down, turning off the power supply, taking card out of PCIe slot, turning the power supply on, booting, shutting down, turning the power supply off, putting the card back in, booting, and rerunning the installer. The UEFI recognized a new device, but the install did not work in the usual way. 
 
Since the card once worked and now does not, that is some sign of a hardware failure, which temps me to try to RMA. It is still possible that the SATA cable or mother board suddenly failed instead of the audio card, and I suppose I should try a different SATA cable before RMAing. (The way my cabling is, that is non-trivial to do.) 
 
Anyway, just a data point.
 
Edit: Write after posting this, I just remembered. A Windows update just happened. That is what changed!
Edit2: Uninstalling the update that occurred after the card was last working has not fixed the problem.
 

I also tried the advise given at this URL, and delete information stored in my local appData. That did not fix the problem.

Edit 9/25/2021: My Nu Audio card, was unexpectedly working fine for no particular reason on boot today. I'll see if it lasts.

You did disable the motherboard's audio, right?

If I had to guess it has something to do with the asmedia 3.0 host controller and the card's usb/pcie bridge.

 
My X570 motherboard has an ASMedia 3.0 host controller. It uses the default driver supplied by Windows. There was a user who was having problems with an X570 / X470 motherboard when running Linux, but I couldn't replicate it, which suggested a motherboard compatibility issue to me. (I guess a forum admin wiped all those old threads, sadly). Maybe it's the same for you?
