Sound Trouble

Before you go barking up this tree, you must know I mean custom menu sound and background music. I, like many others, are experiencing problems and noobs try to give out answers that don’t work. So I need a profeshional,(Sorry for poor spelling) someone who has done this before. The problem is none of the custom sounds I made (except buttonrollover sound) are working. I have windows 7 and the newest version of garrysmod, if it makes the difference.

Make sure you’ve put them all in the correct folders.

I did, all sounds are in the sound/ui folder. And there the correct file types+names.
