I am having audio trouble: All audio outputs will occasionally put out crackling and skipping for days or hours at a time, other days its perfectly fine with few hiccups. I have tried the following to no success:

  1. Tried different headphones .
  2. Used both direct connection to the motherboard for audio and through the case's connection.
  3. Replaced and downloaded all drivers.
  4. Tried different power outlets.
  5. Replaced the motherboard.

    I'm kind of out of ideas. I might get a different PSU (I got an 850 for a 3080 but will probably go down to a 750.) Maybe there is some grounding issue?? Any help would be greatly appreciated!

Try installing Latencymon and see if it shows up there. A good guide here with a link to the program. You'll need to have the program running while the errors occur.

I tried Latencymon too, sorry for not mentioning it. It didnt detect anything even in the middle of crackling.


PC Specs?

Motherboard audio drivers up to date?

UPDATE: Interesting... latencymon finally picked up something. It suggests my "system seems to be having difficulty handling real-time audio and other tasks. You may experience drop out, clicks or pops due to buffer underruns." Later it also added "One or more DPC routines that belong to a driver running in your system appear to be executing for too long." All I have experienced is audio problems but I wonder if there is more Im not seeing.

Any suggestions as to the issue here? I turned off CPU throttling for one.

Did you ever have a different OS on this PC?
Nope, just Windows 10. Its a fresh comp, and as I said I already just replaced the motherboard.

After fixing one driver, the problem drivers are not one, but a different one keeps popping up. Storpot.sys seems to be the most common. Im thinking of testing another PSU, maybe there is some power problem going on.

Try a clean Windows install. I've never heard of that SSD before so that could be a potential weak spot.
Oh Ive done that many many times now (on my 3rd MB and 3rd windows reinstall for instance... :( )z

If it helps dxgkrnl.sys and storport.sys are showing up high latency. Ive seen others report this with audio crackling but they found no solutions. (all I have done targeting that specifically is updating drivers and turning on prefer max performance in NVIDIA settings)
