How to Enable S/PDIF Digital Output
The computer is equipped with an optical digital audio output
port called S/PDIF. You will need to connect the output port to
an external DTS, AC3, or PCM audio processor in your home
audio system via an optical digital audio cable (not supplied.)
To Enable S/PDIF output, do the following:
1. Double-click the speaker (audio) icon at the right hand
corner of the task bar.
2. The following box will appear. Put a check on S/PDIF
Output Enable to enable S/PDIF output port.
Note: The S/PDIF port is located on the left bottom edge of the
computer. When you enable this port, all other audio functions will not
work. There will be no sound from the speakers or output in the audio
ports.
