Been googling quite a bit, and found plenty of people with this issue but can't seem to find a thread anywhere where it was actually fixed.

Seemed like a few of the threads on here were getting some helpful responses, so figured I'd give you guys a try. I'll be on for the next few hours so if anyone wants to try anything rapidfire and have me let you know how it goes feel free to jump in. Otherwise I'll check back again tomorrow night after work. Please help before I lose my mind on this. Seems to only happen in graphically intense games (noticed it a ton in Mass Effect Andromeda and For Honor). Not at all in stuff like Hearthstone and Overwatch.

DXdiag attached. LatencyMon images, and trace.etl as well.

I'm assuming it is a DPC latency issue from everything I've read so far, but I'm certainly no expert so open to testing out anything. Getting the audio crackling through USB speakers, usb headset, speakers using the mainboard audio input, audio via display cable, and via hdmi. Have tried disabling all audio devices except the one being used, and a bunch of other stuff, but like I said I'm willing to walk through whatever you guys want to throw at me.

As with others, your issues seem to stem from your display card. Have you tried other NVIDIA drivers going back as far as you can through their server; however, do not go back before May 2016 since your card was not available to consumers prior to that month.


If the above fails, I am also seeing a trend with many of these issues occurring with systems that have a pretty high amount of RAM. Is all of your RAM from the same kit? If it came from more than one kit, were the kits the exact same manufacturer and type?

It might be worth checking your RAM modules even if they did come from the same kit(s). Normally, I'd recommend Memtest86+, but that could take some time to run with that much RAM. You probably should still test, but if nothing shows up after a day of testing, test with the following procedure. Before I outline, here is the guide to testing with Memtest86+ : Test RAM With Memtest86+

  1. Remove half of your RAM from the system. Pay close attention to ESD safety. Keep your RAM configured for dual or quad channel if applicable.
  2. Test your latency issues with the first half of your modules installed.
  3. Test your system with the second half of your modules installed and the first half removed.
  4. Let us know if either half of your modules provide better performance.
 
Hey, thanks for the reply.

Mem was part of the same kit. I had run a Memtest86+, however definitely didn't leave it running for long enough. I will give the memory and older drivers a shot later tonight and report back.
 
Progress! So though I was sure I was getting the issue through my monitor, after reverting to an older driver, and seeing the fps tank(and the issue persist), I went back to the latest driver to see if something else I had done had messed with the FPS i was getting. When I did this, sound defaulted to coming out of the monitor (connected via displayport cable) and I do not appear to be having the issue.

So it looks like the issue is a USB driver then? Or some kind of conflict between the USB and something else? For USB i've got 2 that stick out
ASMedia USB 3.1 eXtensible Host Controller - 1.10 (Microsoft)
Intel(R) USB 3.0 eXtensible Host Controller - 1.0 (Microsoft)

Both are the latest versions, and I can't seem to replace them with anything else, every time I uninstall them, they auto-reinstall the same driver after a restart.
I have the option to disable the ASmedia controller, which I have tried and hasn't helped the issue at all, but no option to disable the Intel one. Since I can disable the ASMedia one and still have the issue I think that would point at some kind of issue or conflict with the Intel one? I've tried every USB port in the machine and problem persists on all.

Thoughts on what to do next?

*Edit: To clarify my ramblings a bit, still have the issue with anything connected through USB or audio port (my speakers and headset) however sound through my monitor via display port cable appears to not have an issue
 
You're leaving out an important possible conflict: Have you tried disabling your audio device under Sound, video and game controllers?
 
Alright, since you can't disable the Intel USB controller, try running something that has the audio issues with all USB devices disconnected. You won't be able to interact with the system since your mouse/keyboard/game controllers would also be disconnected, but see if the audio is any clearer.

If you have already tried that, or if it does not provide any positive results, see if your audio is affected while running a Furmark test: https://www.sysnative.com/forums/hardware-tutorials/3907-furmark-display-card-stress-test.html - Just play music or turn on a video while you stress test.
 
Alrighty, sorry that took a few days, busy weekend.

Running FurMark while listening to some random music on youtube: no affect, didn't notice the issue at all and DPC latencies appear fine.

Disconnecting all USB: Didn't seem to have any impact.
Found some older speakers laying around with green audio wire, plugging it into the speaker out on my mobo, issue persists. However plugged into the speaker out on my monitor I do not have the issue.

So it seems like audio that is going directly through the video cards is ok. Anything going through the mobo has the crackling. Problematic since both my speakers and headset are usb.
 
Also just noticed the issue while playing Hearthstone, typically don't have the volume cranked up so never noticed it before. It's not as pronounced as it is while playing stuff like Mass Effect, but still there.
 
Did you ever try running with half your RAM installed and then the other half?

If that doesn't change anything, contact your motherboard manufacturer and see if it is a known issue. Maybe they'll offer an RMA and we can rule out the motherboard as a possible cause.
