S/PDIF streams can output audio to digital sound systems.

Sony/Philips Digital Interconnect Format, or S/PDIF, is a type of audio connection that uses a special jack. On computer systems, the S/PDIF connection is typically used to output audio streams to digital sound systems, such as a home theater speaker system or a digital audio receiver and is found on sound cards and newer motherboards with on-board audio. Users who prefer to use an analog sound connection or another audio interface can disable S/PDIF output completely.


Step 1

Click on the "Start" menu button, click on "Control Panel," click on "Hardware and Sound" and then click on "Sound." The "Sound" control panel will appear.
