Default 1.7.10 Forge Minecraft Sound Location?

[aJeBosh]

I'm trying to change the sound it makes when every mob dies.
I've made a new resource pack of my own and inserted an OGG file, changes the sounds.js to the correct files for a zombie for example.
Yet, once I actually jump into the game, every now and then it plays my file but sometimes it plays the original zombie death sound.

I assumed this is only possible because its taking from the games default sound files.
But..I cant for the life of me find where those files are stored. Any ideas?

Thanks.
