I have a Napolean Dynamite sound board in which I saved one of the sounds called "What" as a notification sound. It shows up in my list of "Notification ringtones" on my phone. However, it does not work or produces any sound. I went into the /sdcard/media/audio/ and the "what" mp3 sound file is not there. Again, it still shows in my choice list of Notification ringtone. Since the sound does not work and is not in the /sdcard/media/audio/, how can I get it off the Notification ringtone menu?
