15) Internal Audio Connectors (4-pin CD_IN, AUX, VIDEO, MODEM)
These connectors allow you to receive stereo audio input from such sound sources
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 mono_out (such as a
speaker) between the onboard audio and a voice modem card.

16) Serial Infrared Module Connector (5-pin IR)
This connector supports an optional wireless transmitting and receiving infrared
module. This module mounts to a small opening on system cases that support
this feature. You must also configure the setting through 4.4.5 Peripheral Setup
to select whether UART2 is directed for use with COM2 or IrDA. Use the five
pins as shown in Back View and connect a ribbon cable from the module to the
motherboard’s IR connector according to the pin definitions.
