I loaded up a previously saved game, and ever since then there are times when I try to enter certain areas and an extremely loud feedback sound occurs. These are areas I have entered before with no problem, and this sound issue never came up until today. Can anyone explain this? I can't go any further at this point because I can't stand to enter certain areas because of the sound. I don't want to just turn the volume down because I know I might miss something I need, and I also know it just shouldn't be doing this.
