Click on the S/PDIF tab and the following screen appears.
Playing Audio (48 kHz Output): Playing Digital Audio to Digital S/PDIF
Output. Choosing this option allows the output digital playing audio from
your computer like DVD, VCD, digital CD, MP3, Wave... etc through S/PDIF
in 48KHz sample rate.
Analog Input to S/PDIF-Out: Convert Analog Input to Digital S/PDIF Out.
This function is to convert analog input audio like Line-in, CD-in,
Microphone-in signal to S/PDIF digital output in real time. This is useful to
transfer the analog audio from one device to the S/PDIF interface of another
such as the external decoder or the amplifier of Home Theater.
No Output: C-Media AC'97 CODECs supports S/PDIF output with analog
output at the same time. When choosing this option, S/PDIF output signal
will be terminated. Otherwise, it would be transmitted all the time.
Serial Copy Protection Option: When this option is enabled, the copyright
of S/PDIF output audio data will be asserted. Therefore it can be only
recoreded once but can't be copied again according to SCMS (Serial Copy
Management System) mandated by Audio Home Recording Act of U.S. in
1992.
