iPhone Anyone Else Able To Use Sound Themes?

So once the iOS 6.x jailbreak from evasi0n came, I immediately started adding the main tweaks, iFile being first and Winterboard second. After I downloaded the two, I then started modifying iFile to where I could set up a system of adding outside stuff to iFile. One of those things that I added to iFile was this theme I've been working on that I would put on my iPhone 5. The theme has been successful in changing just about everything except the sounds. In the past, I was successful in making themes with sounds or just separate themes that only included sounds. The way I have it set up is this:

ThemeName.theme > UISounds > sound files in .caf

I've been trying to figure out multiple ways to see how I would get these sounds to work on my iPhone 5. I found the folder in iFile that has the original sounds, and they look to be about the same, meaning having the same file name and still being a .caf file. I doubt size would be an issue since I've had sound files work in the past that were big. Absolutely none of my sounds work. I even tried taking the UISounds folder out of this theme that has about everything and made a separate theme, but that didn't work.

I guess my next step would be to download a theme from Cydia that supports iOS 6.x and see how they got it to work, or to download a sound theme from Cydia that has worked in the past. Anyone know of any way I could fix this sound issue?

 

Yeah. In the end, I ended up doing this. Do you think it'll ever be possible to do it the other way? I use to make multiple themes that way besides doing this. Eh, oh well. I did make a back up folder with the original files. I did not, however, do it for apps since I can just delete and reinstall it to get their default sounds back.
