right click Start to Explore click on that, go to C: down to Windows and in that folder is Media, click to open to see if you have the incorrect sounds in there. They also could have been changed by your using another program that changes them. right click on the sounds there and go to properties and click on that. you see that they can be changed back to another format - mine shows that it is looks like a a small wmp on them, type of file is "wave sound" , under that is "Opens with:" and I have "Windows Media Player" so you know what to change it back to on clicking on "Change" you will see a long list of everything that has an icon, look for the correct one and select it. Now, if Windows Media Player is missing, Browse to Program Files, Windows Media Player folder and to the correct icon in it.
I had mentioned that I had replaced them all with a Media folder [("new folder" renamed)right click on the desktop and there is a list to New and on the side, is a Folder] on the Desktop. I had put other sounds from 2 other sources in there plus winxp sounds. This is an alternative solution. Once all your sounds are in THAT folder on the Desktop you can under Edit on the top of your Media file and select all. I have the red X that will delete them all if you haven't that move, over to File and delete is there. Now you can replace ALL your Media sounds from the Desktop folder under "Edit, select all, and copy both in Edit, hold your left side mouse pointer down on any media sound move the entire sounds listed over into youe Media Folder, this is called Drag and Drop when you release the click. If you can store that folder on the desktop in a floppy or a flashdrive. save it for any other problems with Media and you can delete the Desktop Media folder. Darrell
I am unable to change the sounds associated with certain events by going through control panel-- sounds and audio devices--sounds. When I make changes they do not stick. They change back to what they were before.
