10. Internal audio connectors (4-pin CD1, AUX1, MODEM1)
(on audio models only)
These connectors allow you to receive stereo audio input from sound
sources such as a CD-ROM, TV tuner, or MPEG card. The MODEM
connector allows the onboard audio to interface with a voice modem
card with a similar connector. It also allows the sharing of mono_in
(such as a phone) and a mono_out (such as a speaker) between the
audio and a voice modem card.
11. Digital audio connector (4-1 pin SPDIF1) (on audio models only)
This connector is for an S/PDIF audio module that allows digital
instead of analog sound output. Connect one end of the audio cable to
the S/PDIF Out connector on the motherboard, and the other end to
the S/PDIF module. (NOTE: The S/PDIF module is purchased
separately.)
