My card has been sitting in the box for two months, waiting for me to have time to do something about it...

 

I guess this is as far as you can get at the moment. Although you likely get just as good latency figures with something like RME ADI-2.

 

 

Why would it need to be same application? You can stream Tidal/Qobuz through Roon+HQPlayer or something else. And Netflix through Netflix application. For TV I would assume HDMI 2, either through normal copper or one of the new optical extenders (for projector).

 

For similar use case I've been using newest NUC's with HDMI 2.0 connected to 4K TV and then external DAC. Video playback goes through whatever (from files through VLC) and audio playback through HQPlayer. For audio-only playback latency doesn't matter and for video use cases it works fine. If you want, you can also put audio with video through HDMI and then you don't really have sync problems in practice. And YouTube won't give you DSD audio anyway, so that's not an issue.

 

Challenge is if you want YouTube and DSD upsampling together. That can be done with HQPlayer for example, but then you need something like VLC to deal with latency synchronization between the two.

 

Yes, thank you. You are correct of course about the multiple programs, I worded it poorly.

Does WASAPI Exclusive work correctly

Yes.  When Qobuz is set to WASAPI Exclusive, videos with audio on sites like CNN don't play and you get an error message saying 'something went wrong during native playback'.  Note that my Nu Audio card is set as the default audio device because it's the only audio device in my system.  'Allow applications to take exclusive control of this device' is enabled in the Advanced tab of Speaker Properties.

 

However, when I set Qobuz to use ASIO, audio from CNN gets played together with the Qobuz track.  So, what does this mean?  Clearly, ASIO is not getting exclusive control.  So does this mean that ASIO is going through the Windows mixer and I'm not getting bit perfect output unless the source material matches the sample rate and bit depth set in Speaker Properties?  If I am stating this correctly, please confirm and I will relay this message to EVGA support.  If this is true, then I have to conclude that the EVGA ASIO driver isn't working properly.

 

In Device Manager, the Nu Audio shows up as Device USB\VID_3842&PID_3100\00000030.

Sounds like WASAPI Exclusive is working correctly, but ASIO is having unexpected behavior. ASIO should essentially work the same as WASAPI Exclusive, except that you get things like native DSD support which WASAPI doesn't have.

 

So I'd say there is something going wrong with the ASIO driver.

 

Have you tried what happens if you play CNN or something while playing DSD natively through the ASIO driver? That could be used as a suitable case for pointing out wrong behavior.

Measurements were almost boring to do, audio band performance is practically identical with both 8x PCM rates (352.8/384k) and DSD256 (also 48k DSD seems to work correctly).

 

By "48k  DSD", I take it you mean DSD1024? Thanks.

No I mean DSD at multiples for 48 kHz base rate. IOW, 3.072/6.144/12.288 MHz in addition to the usual 44.1 kHz base rates of 2.8224/5.6448/11.2896 MHz.

 

Unfortunately most DACs on the market today don't support DSD at multiples of 48 kHz base rate, although it is only matter of switching the clock same way as is already done for PCM. So they have gone through some extra effort to not support it!

Since the first image is down about -85 dB, it makes maximum reconstruction accuracy for PCM 44.1k family equivalent of about 14-bit resolution. This is quite good result for PCM mode. (practically same as Pro-Ject PreBox S2 Digital)

I understand from the designer that the measured performance (nonlinearity and noise wise) can be improved  by swapping out the AD8056 for another op-amp, such as an OPA1612.

 

The AD8056 was chosen on the basis of its sound quality, after trying several options.  It’s interesting that it can achieve respectable electrical performance with relatively low open loop gain (71dB vs 130dB plus), hinting at good native linearity.

Good that they left easy option for swapping the opamps and documented it. Many motherboard manufacturers do the same for their better motherboards too. If one wants to get (even) better measurement results.

 

AD8056 is also high speed, maintaining fairly low distortion even at high frequencies, which is important for the first analog filter stages where there's quite a bit of high frequency noise present.

 

At some point I may try with something, I have a lot of different opamps from my own projects, so no need to even buy anything for that. Just too busy to do it in near future.

Hi rickca,

 

I sent you a PM.  To make a long story short, ASIO appears to work fine in other applications, such as foobar2000 or jriver.  More testing with Qobuz is needed at this point.

It does not work right with Roon playing DSD.  Have contacted evga tech support on the issue for months.  Once DSD is played, Roon will not release the device.

I don't know if my issues were the same as yours, but this card sounded great- for one night! I was really excited at how good this thing sounded using Roon>HQPlayer 11.2MHz DSD. On the second day the it wouldn't make a peep, and hasn't since despite my efforts. Sadly I think I will have to return it. I simply cannot seem to get the drivers to install after uninstalling them as per instructions. I'll gladly try again if anyone has some suggestions. It seems to fail after preinstall is sufficient. the more window info seems to indicate failure at creating desktop icon or something similar. EVGA_Lee?

Did you reboot after uninstalling?

 

Are you sure the driver isn't installed?  Even if it didn't create an icon, the driver might be installed.  If running Windows 10, check add/remove programs and see if EVGA Nu Audio Driver 4.66.0 is in the list.  If it is, make sure nothing is muted in the EVGA GUI and that you have the intended playback device (speakers/headphones) selected.

 

I don't use Roon so I can't help you there.

Thanks for your reply. Yes, I rebooted. There are some files for the driver, but the device still isn't recognized and is not available.
