11. Front panel audio connector (10-1 pin FP_AUDIO1)
This is an interface for the Intel front panel audio cable that allow
convenient connection and control of audio devices.
By default, the pins labeled LINE OUT_R/BLINE_OUT_R and the pins
LINE OUT_L/BLINE_OUT_L are shorted with jumper caps. Remove
the caps only when you are connecting the front panel audio cable.
12. Internal audio connectors (4-pin CD1, AUX1, MODEM1)
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.
