Can you tell us about your CPU and motherboard? How high is the CPU utilization % when the stutters occur?

Try using òlder asmedia driver. See nu audio driver 02.04 thread.

You might want to go into the NU Audio software and go to setup. Next use the arrows on the side to go to advanced. On that screen you will see "preferred ASIO buffer size" by increasing the buffer size you might get less audio drop outs.

I tried increasing the ASIO buffer size but did not help unfortunately.
 
I have been in contact with EVGA support as well and they are wanting to RMA the card but it doesn't seem like it would be a hardware issue. Seems driver/software related but who knows.
 
Should I try a different x1 slot or maybe even put it in a x16 slot?

Were you experiencing similar issues and are you referring to version 1903 of Win 10?
 
Thanks

Reinstalling windows and setting up everything again is not something I really want to do so I think I may try the RMA process. It probably won't fix the issue but worth a shot until EVGA figures out what the actual issue is.
 
Not happy they are expecting me top pay for shipping to return the product though as it is clearly an EVGA issue.

I actually liked the AE9 but would actually experience complete loss of sound at random times and quite often. Sometimes restarting the SoundBlaster Service brought it back but not always and became too much of a nuisance.

Checked in with our Audio team, and they suggested to try and disable some power saving-related items (such as C-State) in your motherboard BIOS to see if it helps.
 
One of the issues we saw previously with the other ASMedia driver is that the new AMD CPUs mess around a lot with the power saving features for USB, and this might be related to that issue.

I reinstall with win10 1903 with the august patch and it fix my cracking sound problem.

I decided not to RMA the card and just returned it to Best Buy for a refund. I don't believe there is anything wrong with the card and is definitely a software/driver issue. Hopefully EVGA is looking into the issue but based on my past correspondence with support they don't seem to be.

Ended up returning to EVGA myself, such a shame-the quality was spectacular..but drivers...not even close. Such a bummer. Waiting for my AE-9, now.

I reinstall with win10 1903 with the august patch. That solve my problem. I am using 3900. U can find the win10 iso on the net.

Im amazed that the NU card has such basic problems, it seems like this product is not even ready to be sold to customers yet. OP should get payment from EVGA for beta testing their product.

Video stuttering and audio drop out when playing a video in a browser... After 35 years of using PC's, never have i experienced such basic problems with a soundcard. What is next, pc cannot boot with NU card installed ?

I've ran into and "fixed" (worked around really) a similar issue. Problems like OP's started occurring when I switched my nu audio card to another pc. Old pc had a b350f strix, r5 1600,r9 290 trix, evga 650 white psu. I didn't have any problem with the audio card in that setup, it was used with hd58x and an Aiyima ao7 + elac b6.2 setup. Problems like audio/video microstutter started when i moved the r9 290 and the nu audio card to a ga z270x gaming 7 , i3 8350k (coffee lake microcode added to latest bios manually), 550w evag psu, HTPC. Disabled C state in bios. When playing games or watching certain videos stream on certain app i get a/v microstutter. I think it's related to gpu/video streaming (or network?). I already tried a pcie lan card(disable onboard lan) , 14$ ugreen one, and it didn't change anything. I don't have audio stutter while downloading in the background and playing music with foobar, only streaming video or any else that uses Gpu.Another thing is I get more emi than I'd like when gpu is on full load, but my smsl sk10 suffered the same thing connected to the any usb port on the aourus gaming 7. Some things I've done to work around the microstutter is I use Microsoft edge or the Brave browser since strangely enough, I don't experience any problems while using those browsers and streaming videos. Most problems happen on Firefox. Another thing to note is i use a fio D03K connect to my tv, to transmit analog audio into the line in on evga card (since the evga doesn't have a toslink input like the soundblaster zxr) ; but don't notice any effects with it connected or not for pc playback.
