SOUND on TI-NSPIRE CX CAS

There has to be a way for me to get sound on my CX CAS because I have gbc roms on it but no sound. How do I get sound to work? What do I need to buy/download/configure? HELPFUL input only please. Thanks. Saying things like "no it isn't possible" is not an acceptable reply to my request. There's no such thing as "not possible" when it comes to computer programming.
