1.9.2 Audio-I/O Board Features
The audio-I/O board consists of microphone port, line-in port, line-out
port, and MIDI/game port. These ports accommodate the external
audio devices.
Figure 1-12 Audio-I/O Board
The internal connectors on the audio-I/O board are useful for system
housings with built-in speakers, microphone, amplifier, or auxiliary
devices. With the internal audio connectors functioning exactly as the
external audio ports, you can utilize all the sound features supported
by the system board.
Since external speakers, microphone, and other audio devices give
better sound quality, the external audio ports take higher priority than
the internal connectors. When you attach external audio devices to
the ports, the internal audio devices are automatically disabled.
