Audio I/O Support 2
The 12” and 7” cards have connectors for audio I/O located on the edge of the cards, as
shown in Figure 3-1 on page 34 (12” card ) and Figure 3-2 on page 35 (7” card). “Audio
Connectors” on page 47 provides specifications for these connectors. As shown in Figure
2-9 on page 30, Figure 2-10 on page 31, and Figure 2-11, the audio output cable is
connected to the audio output connector on the PCI card and then plugged into the
audio out connector on the CPU’s main circuit board. The audio input cable is connected
to the audio input connector on the PCI card and then plugged into an audio source such
as a CD-ROM drive or other sound source.
