From the card flyer:

Inserting the included TOSLINK adapter into the stereo jack converts it into a S/PDIF digital optical output, allowing you to connect your Mac or PC to the optical digital input on home theater systems, digital speakers and other digital audio devices. This digital connection lets you enjoy DVD or streaming digital movies on your Mac or PC in high-quality, pure digital format. By installing an optional driver, the digital output can also send Dolby® Digital or DTS™ surround sound as an encoded digital audio stream to your home theater system. (NOTE: This feature is only available on the Windows platform)
