2.17 Internal Audio Connectors
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 a
voice modem card with a matched 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 the voice modem
card.
