(edited for forum rules/fix)
somethings you can try though that might help
try:
switching your graphics backend to openGL (works better for me might for you)
put your AA to none
if your cpu has more than 2 cores put a check on OpenMP Texture Decoder
in Config enable idle skipping (for harvest moon it helps me maintain fps to 30 -31)
i had sound stutters before i made these selections i use doplhin version 4.027 for this game,
because your system is a little slower and its sounds like, sound is your only concern and if your scared of overclocking use dolphin 3.5 the HLE sound is not connected to framerate like in 4.0.
so even if you have low fps you will not have sound stutter/crackling.
Just know that 3.5 is not supported anymore, if it works well for you in this game as far as sound goes great! but if 3.5 causes random crashes for you, or other bugs your out of luck because as stated by shonumi its no longer being supported.
