[SOLVED] Sound Crackling, high DPC

I had a Dell Inspiron a few years back that had the same problem. I think some Dell updates eventually fixed the problem, but I really cannot recall. Have you checked Device Manager to see if there are any yellow exclamation marks beside any hardware? Do you have all Dell updates up-to-date? I think it was another driver causing the speaker problem, such as a modem driver, etc.

Yes... i have seen the Device manager... and also i tried to update the audio driver and network adapters/controllers... and still the same.

here is a quick pic of view...

I think that laptop user are having more often problems with Windows 8/8.1 rather than desktop users... it is just my opinion... :huh:
 
Would you have any external speakers you could hook up, just to rule out the built-in ones? also, do you have any third-party audio programs installed? Not audio players, but a program that would 'enhance' the speakers' sound, such as Dolby, etc.

I did not try with external speakers, but with headphones the situations is the same.
I only use Dell Audio software which comes with the updates I guess... :/
btw... Dell Audio software worked fine on Win7.
 
Then the only conclusion I can come to is that either the sound card chip and/or the drivers are somehow incompatible with Windows 8.1. I would consult the Dell support forums for others possibly having similar issues. This is likely vendor hardware/driver specific and it seems you have tried everything you can at this point. Let us know if you find a solution, please.
Sorry I could not be of more help.
PS: just a last thought: did Windows Update offer any updates for your Dell sound device?
 
Huh... i tried to reinstall almost all the drivers... even try to use Intel specific drivers instead of Windows drivers and nothing has changed.

I will look the thread... thanks for linking it here... ;)

Hi,

sorry for the delay getting back to you.

DPCs/ISRs seems quite normal on your system. Anyhow, I don't like a high IO activity, which seems to relate to aswSP.sys driver. Could you please try removing Avast from your computer completely and let us know if the issue persists? In case it does, please generate a new XPERF trace as well as do the following:

  1. Open an elevated Command Prompt by right-clicking on CMD.EXE shortcut in your start menu and selecting Run As Administrator from the context menu.
  2. Type the following commands:
    HTML: 
    FLTMC filters > %USERPROFILE%\Desktop\FLTMC.txt
FLTMC instances >> %USERPROFILE%\Desktop\FLTMC.txt
  3. Attach FLTMC.txt file from your desktop here
Thank you.
