[android, samsung galaxy s4] fix to crackling audio?/concerns about crackling audio

[stealthbox]

hey, i just had a quick question if there is any way to fix the audio crackling sometimes on my samsung s4 galaxy through adjusting the settings. if there isn't, should i be worried about crackling audio damaging the phone's speakers? specifically, the incident of the audio crackling is from at the end audio that plays in danganronpa when you press the triangle button to analyze your surroundings.
