Missing the Sun/NeXT .AU audio codec.

How do I get it back? Media Player 12 won't play any .au files.

These are the audio codecs WMP 12 says are installed

I already have CCCP installed. WMP 12 is supposed to be able to play .au files. I tried uninstalling it and reinstalling it through programs and features. Still won't play .au
