11. Internal audio connectors (4-pin CD1, AUX, MODEM) (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.

connect the Intel front panel audio cable. By default, these pins are
shorted. Before using this connector, make sure that your audio cable
and the front panel audio module (if available) comply with the Intel
Front Panel I/O specification.
