Hi I just got the EVGA NU Audio and installed it.
It has some issues in Playback - it stutters now and then when I tried to play back the Witcher 3 FLAC Audio files.
(tried 32 Bit, 191200, 352800, 384000khz)
I am not sure if there is a correlation to "CPU" Demand - like starting an App or anything alike.
Also It seems that I have to do a restart now and then to get it working again after some time (energy saving?).
 
Second, Using it in BF V I get strong distortions on the sounds - 384000khz
 
Are there any hints what to check or known Bugs in the driver?
 
DXDiag also shows a "Error: resolving further soundinformation results in an error" on start up.
 
 
DX Diag Shows the following in case it helps:

Thank you! If I can provide further information just let me know.
 
I just opend DxDiag again today, yesterday I thought the PC pulled some updates - the Error Messages from DxDiag do not show up again, but the slight stuttering now and then still remains at playback of FLAC Audio.
 
Kind Regards,
 
 
MR

I was trying to listen to some musik today again during work. I had a lot of stuttering - I got disappointed some time and sat back on my chair - and the musk played and played and played.
 
I was amazed and wanted to check if i saw anything pinpointing to a cause or the lack of it in this case. The moment I move my mouse (USB Connected Logitech G900 - it shortly after wards starts stuttering.
 
This is to 95% reproducable - the time until it starts to lack is not consistent - but leaving the mouse alone results in non stuttering musk playback - moving the mouse will result in time near stuttering of the playback.
 
Any Idea to check? Bandwith USB, IRQ - Stuff? I would look if I knew for what an where...
 
Edit: Moving to a diffrent MoBo USB Port shows noch change - unplugging or pluggin in the mouse causes a real hang on the sound card while the mouse is being "installed"  - only swithichg the sample rate will cause a playback again.

I think we've narrowed it down to being a device/IRQ conflict, which helps.  It could also be a bad card, but I've run into similar issues in the past with other sound cards and usually turned out the card was fine.  In one case it was a card, but in another case it turned out my mouse was going bad.
 
Please list what you're using for USB devices.

You'll need a few more posts before you can post links (it's a forum anti-spam measure), I believe.
 
Just quickly browsing, because I have to go take care of some errands, but one of the USB Controllers in WDM shows a "SuperSpeed USB Hub (Non Functional)" listing, and I wonder if that has something to do with it.  Also, I would also suggest checking the Human Interface Device menu, as there are some USB-related devices tracked in that menu, as well.

Damn ok, next problem - the nua app wont work. 
I saw the second pic on first start up and the errors shown on each try to start the app.
 

Hi, thanks for the response.
(Just as a Tipp for anybody - dont install the ASMedia Driver newer then the one your board partner supplies… for me this was Asmedia_USB3_V1.16.35.1 and the new one I Believe Asmedia_USB3_V1.16.55.x)
 
If I uninstall and do a clean install the nu software works (before it just loaded and nothing happend).
 
I get the above runtime errors this time only for spidf and line in, then another time again all four. I could then open the software and hear audio.
 
Now if a do a clean boot again, nu audio is not installed as an audio device, even though it worked fine before the reboot. I can start Nu Software but the audio device is gone. I do see a Device in the device manager now (yesterday night some times 2) that dont have a driver configured.
 
Is this due to the runtime error?
I also noticed that i dont see a firmware version in the Nu Audio Software - is that ok?

 
 
Yesterday this had no effect, but now i just tried the usual "install drivers" and it worked. It showed up as the nu audio device, but still missing the spidif if could select before. But now I can at least use the headphones!
 

I just tried FooBar again - it wont play for  me and just shows an error code

I just tried FooBar again - it wont play for  me and just shows an error code

 

I'm not a normal foobar user, but was trying it out a week ago after getting the nu card and if I remember right was getting a similar error to you off and on. I'll try it again tonight if I get time and let you know what happens.

Yeah I get the same error if I try to play anything through foobar when evga nu is set to 32/384000. If I close the player, set the nu to 24/96000 then reopen foobar it will play fine.

Also, can you guys verify something for me?  Have you changed the output to the NU Audio card in the foobar configuration?
 


 
You might also have an option for DS: Speakers (EVGA NU Audio), which should also be acceptable.
 

I just did a short test this Morning - my Logi G900 was connected via USB cable - being a wireless i pluged the wireless adapter on and so the mouse is not directly connected - the crackling is still producabel by mouse movement.
 
This is starting to sound like voodoo - but if i put my mouse cursor in the lower edge of the screen, i dont get the crackling when moving as - if i move it over windows and has a graphical effect it seem to be more…. could the GPU be putting spikes on the PICE or something? (Or the crackling is not correlated to my mouse actions…. damn :-) ).
 
FooBar gives me an 0x80070057 Unrecoverable playback error if i try to start playback and set the NU as output (not asio as i am not seeing it)
 
I will try some more on the weekend.

I got the 1.0.3 driver and I also had those two error boxes appear. I will borrow a pic from an above post.
 
Thats what it looked like. Didn't pay it much mind. The card still works seemingly fine.

Ok, so I can say that I don't the the error messages any more (runtime).
 
I do still have the distortion noise, its a lot less and seems to need some time of music and my working going on the pc to start, but then its there again - the first mentioned stuttering is extremely reduced.

Thanks for the hints!
I was using it in gaming with no noticeable sound - the "hick-ups" or the distortion (more a crackle) are mainly when I listen to music.
I leave it most of the time at 32bit and 3xxxxx. In Games I never noticed a side effect, strangely. I will do some more testing focusing on that tonight.
