actually, i just solved the problem, what i did was: install forge, but have a backup of a regular minecraft.jar aside. i opened the sound folder in the forge minecraft.jar and copy/pasted everything from the regular one except for the codecs, which is the only thing left in the forge minecraft.jar. since they both had a codecs, i manually merged them by opening the codecs folders, and put the regular codecs classes into the forge one, giving you a sound folder with a bunch of crap in it, and three classes in the codecs folder, which is in the sound folder. no more hissless creepers for me, thanks guys
