I have been having so many issues with this audio crackling and it's driving me nuts. I have tested both Realtek and Windows audio drivers, and crackling occurs on both, although slightly less on the Windows one. I have run tests through LatencyMon to make sure that it is an internal issue with my system. I can't find any fixes online so I created this thread. I'll provide information here:

  • System Manufacturer? ASUSTeK
  • Laptop or Desktop? Laptop
  • Exact model number (if laptop, check label on bottom) G501JW
  • OS ? (Windows 10, 8.1, 8, 7, Vista) Windows 10
  • x86 (32bit) or x64 (64bit)? 64 bit
  • Service pack? Not sure
  • What was original installed OS on system? When I received it last year, it had Windows 10. I reset the laptop while it had Windows 10 installed when I first received it
  • Is the OS an OEM version (came pre-installed on system) or full retail version (YOU purchased it from retailer)? OEM, I think
  • Age of system? (hardware) Laptop was made in 2015. I received it last year from someone else, so I do not know when they purchased it
  • Age of OS installation? I don't know.
  • Have you re-installed the OS? I have only reset the laptop when I received it, so I did not reinstall the operating system
  • CPU Intel Core i7 4750HQ
  • RAM (brand, EXACT model, what slots are you using?) 8GB DDR3 Dual Channel, Samsung, M471B5173DB0-YK0. More info in the Speccy link I provided
  • Video Card NVIDIA GeForce GTX 960M
  • MotherBoard - (if NOT a laptop) N/A
  • Power Supply - brand & wattage (if laptop, skip this one) N/A
  • Is driver verifier enabled or disabled? Disabled
  • What security software are you using? (Firewall, antivirus, antimalware, antispyware, and so forth) Windows Defender
  • Are you using proxy, vpn, ipfilters or similar software? No
  • Are you using Disk Image tools? (like daemon tools, alcohol 52% or 120%, virtual CloneDrive, roxio software) No
  • Are you currently under/overclocking? Are there overclocking software installed on your system? No

I have attached a link below to the zip file of DxDiag, msinfo32, and the trace file.

I have also attached screenshots of LatencyMon.

Hi finalzephyr,

Did any audio glitches happen while you recorded the trace? It looks like some ndis.sys DPCs are running a little long but I wouldn't think long enough to cause noticeable audio glitches.

I'm not sure what you mean. Are you referring to the regular audio popping and dropouts? I only get them when there are certain sound frequencies.
 
I'm referring to part of the title of your post - audio popping, crackling, dropouts. Did any occur while you captured the trace?
 
Can you trigger such glitches while capturing a trace or is it not easily reproduced?
 
Yes, by pausing and playing media when certain sounds are playing, adjusting an audio slider while audio is playing. I can trigger the dropouts and crackling like that.
 
It might be helpful to look at a trace where the glitches are happening so please see if you can capture one and make it available for download.
 
Hopefully this worked. Running a trace is kinda confusing for me, but I assume that the initial command is for starting it and the other is for ending it and generating the trace. I tried to create as much crackling/popping/dropouts as I could.

Thank you. That's correct regarding starting and stopping a trace. I'll have a look and see if I can spot anything.
 
Also, please run the following command in a cmd prompt window and post a screenshot of the output in a reply.

wmic memorychip get banklabel, configuredclockspeed, DeviceLocator, partnumber, speed
