Windows 10: DPC routines executed too long. Popping and clicking sound.

Hello.. i am experiencing this Problem now since.. i would say around 2-3 Month. I have swapped out my Mainboard, changed my Ram, changed my PowerSupply, reinstalled windows, set my power settings to 100% (giving my CPU 100% all the time) etc... still the clicking remains whenever i open something or something needs to load in the background... Here are some results from latency mon...

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. In case you are using a WLAN adapter, try disabling it to get better results. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

storport.sys driver DPC issues (sound)

Hello,

Recently I've been havin' serious sound issues, and no one has been able to help me yet. I don't want to reinstall windows, since it will take me days to get my PC back to where it is now. I also don't want it because I have read that in most cases, reinstalling
windows doesn't solve the issue.

I've already tried the following:

-Latest BIOS update,

-Reinstalled/updated drivers, even rolled back a couple of times,

-Disabled all enhancements.

I have also run a LatencyMon run:

DPC Latency Issue - Random audio popping/crackling

I have been having audio popping/crackling for a few months now. I also get random 3-10 second intervals of pure white noise/static come out of nowhere when watching a video or listening
to music.

I'm not sure how to fix it.

I've tried:

• 
  
  Running memtest(no problems)
  
  Resetting my cpu overclock
  
  Reinstalling audio drivers, updating mobo
  
  Turning off fast startup
  
  Changing/reverting audio formats
  
  Updating graphics driver
  
  and possibly a few others I don't remember.
  

Any help would be greatly appreciated. Thank you.

high DPC latency and audio distortion (crackling and popping sounds)


Hi guys,

Yesterday evening I was watching some youtube videos when suddenly the sound cut out. I turned the volume back up only to find there was a loud staticky crackling pop as the only audio output. Audio output is fine on headphones.

I have a Lenovo Yoga 920 (with highest specs) with Windows 10 home 64x bit. Since the issue arose, I have tried several things:

- disable/enable drivers by REALTEK related to sound, and Qualcomm Wifi Network Adapter

-Reinstall drivers via windows and directly via REALTEK website

- Update Windows 10 OS as well as BIOS

- Messed around with several battery plan settings

- Restored PC to previous backup, then messed around with audio mixer. This helped, as there was no distortion until volume 20, but beyond that it was the exact same issue.

- Lastly, I resorted to just resetting my computer (deleting all files, etc.)

My next step would be to do a clean install of windows 10 but I need to be using my computer and was wondering if there is a better way.

I believe this is a software/driver related issue as I was partially able to fix it by messing with the mixer settings (even when not having restored my PC). However, this "fix" doesn't work since I reset my PC...

I installed LatencyMon, and the results are below:

REPORTED HARD PAGEFAULTS
____________________________________________________________________________________________________ _____
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.


Process with highest pagefault count: none

Total number of hard pagefaults 0
Hard pagefault count of hardest hit process: 0
Highest hard pagefault resolution time (µs): 0.0
Total time spent in hard pagefaults (%): 0.0
Number of processes hit: 0
