Help! Suddenly I am hearing a crackling sound

I recently upgraded my computer and moved all the components to a new case and later switched to windows 7.

While I was on my old system with vista and even after I upgraded some parts, but before I switched to win 7, I had no issues with my sound.

Then I upgraded to win 7 (clean install). I downloaded the latest realtek drivers for my on-board sound (Gigabyte G31M ES2L Mobo) and I noticed that some of my purchased I tunes music made a crackling sound that was previously not there. Since I thought the problem was only with iTunes purchased music (I don't have this problem with music imported from discs) I looked for a solution regarding itunes and found that there were some issues with purchased music and a crackling sound on itunes 9.

But now I am hearing this crackling sound on skype and sometimes when I watch online videos from you tube and the like. I do not hear this sound during gaming or while watching DVDs which is weird.

I don't think the problem is my speakers because I am not hearing the crackling sound all the time with every application as I have stated above

My specs:
Mobo: Gigabyte G31M ES2L
CPU: Intel Core 2 Quad Q6600 @ 2.4
GPU: Gigabyte ATi Radeon HD 5770
Ram: 4 GB DDR2 800
PSU: Seasonic M12II 620 W
Case: Cooler Master 335 Elite
OS: Windows 7 32 bit
Speakers: Creative SBS 2.1 350


Please help me.

Thanks.

  1. I think you should go to control panel > sound > check properties of your default device and test which khz/hz are acceptable for your system. Sometimes having the wrong setting will produce distortions and hisses and crackling and whatnot. You can pick a setting nd then hit test, usually you'll hear a clear chime if its acceptable.

    Since you upgraded your operating system it reverted back to original settings in sound most likely

    Tried it just now and it didn't work :(

    So I went back to the default: 24 bits 48000 hz (studio quality).

    Any more suggestions?
  3. I'm sure someone will have a better idea but, did you consider uninstalling any itunes software and then a reinstall of same ?

  5. I had a similar issue and found a solution that works for me and hope it works for you !!


    Open task manager. Go to Processes tab. Right click on the process that is producting sound ( media player, plugin container for firefox etc ) and choose "Set affinity". Select only one processor from the list of processors available and select ok.


    ** AUDIO BECOMES NORMAL MAGICALLY **


    I am not sure whether is is a hardware issue or OS issue. Someone needs to find out and get whoever is responsbile to fix this.


    Such a big pain ..


    Hope this helps ..
