Sound help

[Ethereal Penguin]

Right, basically I've been searching around for the past 2 hours a way to edit sounds because I hate the chest and door sounds, I've now got the edited files the problem I'm having is the resource folder always redownloads itself whenever I try and start Hexxit, I've tried multiple solutions, searched for mods and everything and I'm stumped, here are some solutions I've found:

Multiple outdated mods

Delete meta-inf (didn't work)

Make a text document in the resource folder called DO_NOT_UPDATE (didn't work)

Resource packs (not in 1.5.2)

Usually I'd just use Google until I found a solution but I must be having an off day because I can't seem to find much in the way of help, I'm also aware I could create my own mod to implement the sounds but a) I don't know Java well enough and it doesn't seem worth the effort just to change 4 sound files, I'm also aware I could just download a mod that changes all sounds but I'd like to keep the originals, just not the chest and door because they drive me insane!

Thanks in advance for any help provided

Edit- After a long search I finally found a mod compatible with 1.5.2 called Audiotori, I'll provide links for both this and the new sound files I created incase anyone is interested.
