This could be the device that is selected. Take a look at your preferences and devices under the "edit" menu option. You may try a couple of different device options there and see if one of those clear this up.

major problems
Hello. I reset my computer and tried opening one of my Audacity files (.aup), and it said that it was missing or had corrupted 99 .au files. My song was ruined. Is there some way I can recover this? I am very sad....

Have you opened up Audacity and tried changing the output device? It's likely a problem with Audacity and not the files themselves.
