Hi Torino460,
 
Sorry to hear you are having problems like I experienced! It has been a while so I will do what I can to help. However, it sounds very similar to the issue my problem.
 
Before you start, uninstall all the Nu Audio Software. The software to uninstall will be: EVGA Nu Audio Driver vXXX (where XXX is the current installed version), EVGA Nu Audio Pro Utility, and EVGA_NahimicAPI 64-bit. This is what I currently have installed, but it should be fine if you are missing any one of these software. 
 
Next attempt to install the Nu Audio Pro software, and when asked to reboot, say no. Proceed to follow the instructions below. 
 
To get to the registry,

1. Press the "windows key" and the "R" key on your keyboard. 
2. Type in "regedit"
3. Replace the entry "Computer", right below "File" on the top left, and paste in "Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\StartupApproved\StartupFolder" without the quotes.
4. Press "Enter" on your keyboard.

This should take you right to the path of the startup folder. To the right, you should see two entries called: "NUAudioInstaller.lnk," and ""EVGA NU Audio Card Pro.lnk." Delete these two keys as these shortcuts will startup the next time your computer reboots. Once you reboot, the firmware updater tool should launch. Hope this helps! 
 
 
 

Well.  Just tried it.  I deleted the line after I uninstalled everything but before I reinstalled everything.  Selected no to reboot and tried to find that line again and it wasn't there to delete again.  So I am still stuck with an expensive high end sound card that will not work.  Does this sound right?  It was shipped with no versions of the firmware at all?  It says 0.0 under firmware version.

Torino460, I just uninstalled, and reinstalled my software to see if I can help guide you on issues that you might be having too. It seems that I was having issues with the reinstall, but slightly different than previously reported.
 
The steps I provided previously was for updating the firmware, and installing the software. Since my card has the latest firmware, the instructions need to be modified a bit as you might be using a card with the latest firmware already.
 
Please note that the below instructions require you touch inside your computer while it is powered on, so proceed with caution, and at your own risk!
 

1. Uninstall All Nu Audio Pro software (1. EVGA_NahimicAPI 64-bit, 2. EVGA_Nu Audio Driver v4.71.0, and 3. EVGA Nu Audio Pro Utility).
2. Reinstall EVGA NU Audio Pro_1.0.3_WIN10.
3. Restart Computer.
4. Go through prompts for software install.
5. When prompted, disconnect your sound card by unplugging the SATA connection to your sound card. 
6. Plug back in SATA connection and Windows should detect the sound card properly now. 

 
Let me know if this works! 
 
 

Glad to hear that your card is working now! Enjoy!

Hi.
 
Since upgrading my card to 1.0.3 last week I've run into a problem.  Via the Nu Audio software dropdown, the card was set to two channels when I updated. I normally run a three speaker solution but since that update I've lost my center channel in entirety.
 
I only have three speakers, L, R, and C.  They're analog Polks running through a five channel amplifier.  I've tested the amp channel by swapping inputs and the amp is good.
 
Since I lost center channel function I've tried the following:

Configuring channel via sound control panel 'configure' tab.
Disabling enhancements via properties tab.
Changing bit rate via properties tab.
Uninstalling 1.0.3 and reinstalling.
Uninstalling 1.0.3 and installing 1.0.2.
Deleting entries under 'sound,video and game controllers'.
Deleting entries under 'audio inputs and outputs'.
Restarting and verifying status of services: runtime broker, Windows audio, and endpoint builder.
looking at the registry entries posted earlier.
Removal and clean reinstallation of the Xaudio2 files used by the game I recently installed.
Refreshed Windows via in place upgrade.
 
What I have thought of but have not tried: rolling back the firmware update delivered with the 1.0.3. I do not know how to do this.
 
So I'm pretty flustered.  I've got a setup that is perfect for my needs and which functioned flawlessly until I updated the drivers and firmware for my sound card.  Now I'm down to a stereo solution and I'm hoping someone has seen something like this.

I uninstalled and reinstalled this driver today and got a BSOD when reinstalling the driver. Restarted the system and the installation went through. I haven't noticed any issue with the sound yet, but the software is still unable to change the LED color.

 
This, I am unable to change the LED color too on my NU Audio Pro
 
Edit: I think this happened after a windows update

So, if I submit a ticket, they'll email me an updated driver?
Because that's what I was talking about.
A lack of continued software support for the really expensive hardware they sell.
An evolving feature set would be nice, but also, you know, little things like... Windows 11 compatibility.
For example.

I don't know about an evolving feature set, but as far as I know the features are pretty complete.
Nu Audio Pro driver v1.0.3 is working fine for me on Win11. What issues are you seeing in Win11, not including your original issue with 3 speakers (L, R, C)?

EVGA stopped releasing driver updates for this device when they released the Pro version, some years ago.
 

I literally was about to remove the Nu Audio card and install the Creative Sound Blaster AE-7 I just got into my computer today, I'll try this update and see how it goes.
