Just pulled down and did a clean install.  Can confirm no more Nahimic UAC dialogs.
 
Unfortunately the testing so far on switching between DSD and FLAC (in Foobar as well as TuneBrowser) is ending with the Fail to initialize device error and the device disappearing from the sound control panel. This was after playing a DSD... exiting TuneBrowser, then trying to play a flac.
 
I'll do some more testing... but what I had found in the previous driver with this issue is that if I'm 'gentle' with the transitions between playing PCM and DSD source, I can usually avoid the crash if I play a 16/44 flac before moving on to non-music oriented things like youtube.
 
Off to reboot...  
 
Thought I'd just edit this post instead of posting new.  After reboot, the firmware flashed which gave me hope.  Another reboot, but still the same.
I do have the detailed crash log info from the player... quite a bit of info but one block I found interesting:

This repeats on down the dump 4/8, 5/8 etc with different sample rates.  Hope that helps a bit in the debugging...
 
Also, speaking of sample rates, what exactly does the main 'Sample Rate' combo box setting in the main interface do? I figured since I'm using ASIO it was not a setting that would matter but greatly appreciate any clarification on that one.
 
Lastly, one positive is that I still seem to be able to hold off a crash by playing a flac before exiting, and I'm able to switch between a flac and a DSD in the player (next/prev) without issue.

The sample rate box on the main page is linked to the OS sample rate/bit-depth setting for both playback and recording.  This still matters for things that are not using ASIO or Wasapi.  In ASIO, the NU Audio ASIO driver will match the sample rate/bit-depth of the track, but for anything else, it will follow what you've set in the sample rate/bit-depth setting.  Of course, either the audio source ceiling or the sample rate/bit-depth box will control the overall sample rate/bit-depth of the playback.

Thank you so much for taking the time to post the great explanation! That makes complete sense... it is nice to have confirmation on what that setting affects.

This update does not help.
Everything also shows a 2 window on startup with 64bit and 32bit nahimic.

If you haven't already, try a cleanup utility like cccleaner or uninstall the old drivers with geek uninstaller before installing the new version. I used geek uninstaller and the new version install went fine with no issue on the nahimic UAC messages.

Looks like we may have root caused the issue.  I'll send a file to those affected today and see if it fixes the issue. 

Sound good Lee
I hope the "cheap" Nu Audio will be also support in future, after the presentation from the Pro Version. Pro Version will be nice, but i have the normal one now

We will be selling the original NU Audio alongside the Pro models, so we will still be supporting this product for quite some time.  Besides, most people usually run into issues in bunches (e.g. Windows Update, etc.), so we usually try to take care of those types of issues will all of our products.

Still getting audio drop out with amd 3600x and x570 fresh install windows 1903

I am running an i5 4670 / MSI H97 GAMING 3 / Killer LAN E2205 / Windows 10 64bit system. I installed a new driver.
 
While I listening music and when network download speed is going to high or taking network speed test on internet, audio is start to stuttering. in the test, I noticed a short stutter noise occurs while browser is launched either.

I guessed it could be a system's latency problem, so I tested it with on-board audio and but this didn't happen.

Nu Audio has bugs that result in audio stutters as the network download speed increases.
 
Just done a clean install of Windows 10. I disabled C-State options on BIOS already and tried different Nu Audio and ASMEDIA drivers, changed to USB power keeping settings on device manager, processor state to 100% on power settings but nothing solved this issue.

The "fireworks" and "frequency" LED worked with 2.0.7 but not with 2.1.2.  Is there some setting I need to change to make the software "listen" to the sound output to affect the LED?

I was using the EVGA Nu audio card yesterday just fine and now today it doesn't work at all.  Only thing that changed was that I installed a new ssd (intel 660p) that is completely empty.  My Nu Audio stuff is intalled on my C drive which I did not touch at all...   After installing the new ssd and booting my system I get a message that says, "EVGA Nu audio driver failed to install correctly.  Please reboot your computer and run the installer again."
 
I never changed anything...  Didn't try installing new drivers or anything.  So now I uninstall everything and try to reinstall the drivers and I keep getting the same message over and over...  I get to this part:
 

 
click yes and then shorty after I get this message again:
 

 
What am I doing wrong here?  I never had this issue when I first got the product...  What does it meant to disconnect and reconnect the device?  Restart the computer?  I dont understand that step..

Im still getting popping on the sound randomly since this update..Thought it was a damaged optical cable but still its happening. Feel i know have a ruined expensive card.

Hello Steve712,

this audio card is fantastic, but yes, I still have to set the microphone to "listen" in the windows sound control panel
and send it to the SPDIF-channel (which I am not using atm) to get the mic work properly. My headset is connected to the
back of the Nu Audio Card and I also have selected the "back" settings for playback and microphone in the Nu Audio control panel.

Using the front panel of my case (front panel hd audio cable has to be connected the card) makes no difference. I just hope the
distorted audio playback in Teamspeak 3 will be fixed soon. And finally I found a single black SATA power cable extension
to clean up my build.

Hey Lee,
whats with the Teamspeak issue? Something new to the still existing crackle?

HI, Im getting an error show in Event Viewer saying that the Nahimic service failed to start. Checked the services and it is stopped. Try to restart it and get system cannot find the file specified. Reinstalled the driver and still getting the same message.

This issue is currently being worked on, as they've confirmed this will happen if the Nahimic software crashes.  The software team is engaged in providing a workaround for this issue.

I see that the release notes for the NU Audio Pro Driver v1.0.1.0 indicated that the issue mentioned in this thread with Discord and TeamSpeak has been corrected. What about the drivers for the standard NU Audio Card, has it been corrected with v0.2.1.6?
 
Thanks!

Hey,
 I'm interested in the problems mentioned with Battlefield 5/Frostbite, I installed my NU card today and have had nothing but problems with BF 5 & BF 1, when the games load and you should get music i'm getting static noise like an out of tune radio. Other games I have tried are fine (Doom & Res Evil 2, Formula 1 2018), Music playback is also fine, Just seems to be the BF series/frostbite games. I have been looking for answers to this all afternoon, have tried lowering the sample rate to 16 Bit 44Khz, re-installed drivers, currently on 2.1.10 which I think is the latest but no joy. Re-installed BF 5, initially thought that had fixed it but no, still the same. Think the card will have to go back unfortunately for a refund, any ideas guys as to what this could be???

This one is likely a conflict with the Nahimic software.  Uninstall the drivers, clean out the EVGA NU Audio and Nahimic folders in Program Files and Program Files x86.  After, reinstall the drivers, but choose to not install the Nahimic API.  See if that resolves the issue.
 
That reminds me that I need to follow up if Nahimic got back to us on this issue.
