Hello. When I turn on a loud sound in my computer, such as a music video, the sound coming out of my computer speakers appears to be "cracking", like the noise that occurs when the radio is turned to an invalid channel. This only happens when the sound coming out of the speakers is loud, usually above a certain loudness; quiet audio and turning down the sound level for loud audio does not cause such problems. When the music is loud, it causes a generic "cracking" noise, and the music is almost unrecognizable. This problem did not happen earlier, it grew gradually. Previously, I was able to play loud music on my computer without any problem.

Loud sounds create the maximum motion of the voice coil through the air gap.  Larger voltages cause the coil to heat and expand a bit, continued action can wear/rub the varnish off the coil wires, shorting turns and even dragging or jamming in the gap.  That's what you hear.

It sounds like your speakers may be slightly blown out.  I have two used laptops that have that problem.  A good set of headphones will stop that.  Make sure they are 48Hz supported.  Most cheap headphones say up to 44.1K.

So how do I fix this problem? Do I need to replace the sound card in my laptop? How to do it?

Two choices, replace the speakers or reduce the volume.
