13.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.

This connector is for a front panel Line In jack with a return path for automatic signal switching. By default, pins 1-2 and pins 4-5 are shorted with jumper caps to make the Line In source available from the rear panel Line In jack. Remove the jumper caps if you desire to install the Intel front panel audio cable.
