I noticed an error in the sounds.xml file, after noticing when taking a picture, it was playing the wrong file, so looked at the .xml to verify things.
This is the correction-

There's 2 traces on Previous Menu, the highlighted one above should be removed, as it messes with the proper file playing. Instead with that in, it plays the shutter.wav file instead of screenshot.wav file since it's lookinng only at the 1st one, which is the shutter.wav label.
