I formatted my girlfriends Packard Bell ALP-AJAX C3 (also known as an Easynote MX52) laptop last night and put Windows 7 on it (as was previous), problem I have is since reinstalling the sound is very crackly, there's only drivers I have are those which Windows update supplies.

It has a Realtek HD sound chip, I have installed the official Realtek drivers from the Realtek website but it's exactly the same, the best I can manage is to use the drivers Microsoft supplies but there is still crackling which appears to be based on the activity of the computer, i.e. dragging a window around whilst an MP3 is playing causes it to distort.

Now seeing as this has worked fine on Windows 7 previously, what on earth is going on? I spent several hours on it last night but didn't actually get anywhere with it.

Is it crackly at all volumes? Is it crackly on the internal speaker and on external speakers/headphones?
 
Crackly at all volumes, the Packard Bell website has no drivers for Windows 7.

Playing an MP3 can be OK, but then if you drag the window around it crackles.
 
Missed one..

Is it crackly on the internal speaker and on external speakers/headphones?
 
All I can suggest is getting the hardware id for the audio from device manager and googling that to find a more appropriate driver - a win 7 driver from a different manufacturer or a vista driver even. The realtek sound hardware is used all over the place and there should be a proper one somewhere.

If you're not sure how to get that go to device manager, select the device and go into it's properties, select the details tab and drop down the list to hardware Ids. It will be something like HDAUDIO\FUNC_01&VEN_10EC&..A_LOAD_OF_OTHER_STUFF
 
Have you tried setting the Mic on Mute? I had a similar problem, and for some reason if I muted the Mic then the noise would go away. Unlikley, but worth giving it a go.
 
VEN_10EC&DEV_0660

Which doesn't yield anything more than telling me it's Realtek HD, which I already knew, there's no manufacturer specific driver.
 
Got her to reinstall Windows again and not install any drivers bar the ones Windows does and it works, confused.
 
i had the same problem on my old laptop, if you reinstalled with x64 and not x86 that will be your problem. i dont know why but its what fixed my laptops sound.

it was a Clevo one.
 
I'd already thought that might be a problem wozzsta but thanks for confirming.
 
Daft one but try unplugging from the mains, does it crackle on battery power? Had similar with a dell laptop which had ground loop problems.
 
quick apology first for resurecting this old thread but I'm also having the same crackling on my Easynote C3 notebook. Unfortunately the chaps at realtek have removed this file from their ftp site and I've been unable to locate it elsewhere. PiKe : you wouldn't still have a copy of this file knocking around?? or anyone else for that matter...
