I assume you mean that sound crackles when listening to music with cmus
or mplayer, and that it gets worse while typing or using the touchpad,
whereas an an external USB attached mouse does not exhibit the same
trouble?

In that case, please see [1] and follow the directions there.

Thanks much, and hope that helps,
Jonathan
