Well everybody has their word for a sound, since I cannot hear it, I make assumptions as best I can.

 

I suggest Opening the Laptop to try and locate the sound, If you do not feel comfortable with doing this, take it to a repair shop.

Buzzing is normal???

Probably the CPU fan, this is normal, what model of PC do you have?

Ok, well, what about a sort of "crackling" noise?

 

Is that bad?

I know this is going to be an elaborate step, but trying look into this. It is quite exhaustive. http://support.dell.com/support/topics/global.aspx/support/dsn/en/tree?c=us&journalid=75061444AFDC11DBACD4C3AAA2A5261F&l=en&s=gen&treeid=F5AD0574B42BD1F6E030030ABD625310 

I had a similar strange buzzing/crackling noice with my old laptop and it turned out it was the speakers.  We opened it up and disconected the speakers.  It got rid of the noise, but it also got rid of sound on the laptop (except with earphones).
