Once you find a backup in the backups folder you could either duplicate it and put it in the .saves folder... Just make sure you uncompress/extract the folder. Once you have done this just open minecraft and it should be back in the singleplayer worlds part of the game. If you have trouble finding these folders one thing i do that makes things easier is on the title screen of the game go to options then click on resource packs. There will be a button that says open resource pack folder. You can click on that and then at the top where it tells you all the folders you are in click on the .minecraft folder. Then from there your folders will all be right there. C:\Users\"USER"\AppData\Roaming\.minecraft\resourcepacks. (Note: USER in all caps is a filler for your computers username. whoever is logged in will show there.)

I have noticed this issue with any and all sound. I have not tested in any of the snapshots. Just the single player worlds and the realms world.
