16. Internal audio connectors (4-pin CD1, AUX1, MODEM) (optional)
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.
