Audio Connectors

There are four black 4-pin connectors onboard which are used for various
peripherals' audio signals. The digital signal that comes in through these
connectors is directed through the Ensoniq 1373 PCI sound chip, and the
digital signal is turned into an audio signal which goes out through the
speaker. The TDA connector (J10) is for modem audio; the MPEG connector
(J9) is for DVD and TV cards; the VIDEO connector is (J11); the CD connector
(J12) is for CD-ROMs.
