Why do SOME radio, speakers and hifi with manual dials do a crackling sound when changing the volume. another example is it is so bad it crackles throughout even distorting one speaker for a while and a loud buzzing sound. Is there a way to fix them or is it screwed up? |

| Dirty rheostat. If the knob comes off the stem, you could try one of those air spray cleaners they use on keyboards, but it may just be shot. |

Is either dust & dirt or the metal-film (or less likely carbon) track is scratched, pitted or flaking off. Best solution is to replace the potentiometer.
 You can do a short term fix by twisting the control back and forth a few times to sweep the dust away.
It's unlikely that switch cleaner will get onto the metal-film track through the front, you'll need to open the case as squirt the stuff into the innards of the control. -------------  |
