its not in the speaker because the service office told me that they replace the speaker ...
There was a time when there were people who could repair things, but anymore all they can do is replace parts. You have to let them keep replacing parts until they hit on the one that fixes the problem. The new speaker might have gone bad or there could be a short or loose connection. The problem could even be on the motherboard which might need replacing, but be aware that Dell uses "refurbished" parts, in other words "used".
SO MY QUESTION IS THAT : WHAT TO DO??? IF YOUR AUTHORIZED SERVICE PROVIDER CAN`T FIX THE PROBLEM ?
I don't know what the options are in your country. Best thing with audio problems is to return the laptop for a refund within the return period, because after that you own the problem. Your options look like:
> Sell the computer and buy something else.
> Use headphones or external speakers (assuming the noise is only in the internal speaker.)
> Keep returning to the service center until they solve the problem.
If the crackling is not also in headphones then probably like you said it is not the driver. but to double check run the Dell Diagnostics audio tests. If you do not have the tests then an alternate test would be to use the Windows native driver. Trying the native driver is not as good as running the tests but the reason I suggest trying it is that it is unlikely that both the native driver and the Realtek driver would be having the same problem at the same time.
To install the native driver you have to completely remove the Realtek driver files. There are a couple of ways to do this. The simplest is to go Start>Control Panel>Uninstall a Program. Find the audio driver then right click on it and uninstall it. When you reboot the computer Windows will be unable to find the Realtek driver and so will install its native audio driver.
Another way is to find the driver in Device Manager and right click to uninstall, but select the option to delete the files. If the files are not deleted then Windows will re-build the Realtek driver when re-booting. And if you have downloaded more then one version of the Realtek driver then upon re-boot the next older version will be installed, so repeat the process until all Realtek files have been deleted from the hard drive. You will know you have the native driver installed if you open the Sounds properties and see the words "High Definition Audio Device". The Realtek driver is installed if you see the words "Realtek High Definition Audio Codec".
I`ve did the Dell Diagnostics audio tests yesterday (all pass right ) i`ve re installed several Realtek drivers from the firm site , the audio drivers from dell tech support . didn't fix the problem . i dont have any headphones right now but i`ll try to if it`s still crackling . The bad thing is that the return period is over was a week and i like the inspiron (works for me) , i`ll give it back for repairing i hope they will fix it any time soon.
i read some other post : could the problem be in the audio cables and the way there are connected ???
I can't find mention of an N7100 model, but here is a pic of the speakers in an N7010:
You can see the 2 speakers and their screws. The black line between them is the connecting cable, and the part in the magnified circle is the plug to connect to the system board. So there are definitely areas where the wiring can have a problem. But since the speakers play any noise in the audio system the problem could be anywhere. For example a short in the headphone jack would be heard through the speakers.

I got that picture from the Service Manual. To find the manual for your model go to http://support.dell.com/support/topics/global.aspx/support/my_systems_info/manuals and select your model and then follow the links.
