NOTE
Computer systems that have an unshielded cable attached to a USB port might not
meet FCC Class B requirements, even if no device or a low-speed USB device is
attached to the cable. Use a shielded cable that meets the requirements for a
full-speed USB device.
Connecting to the Audio System
After installing the RealTek audio driver from the Intel Express Installer DVD-ROM, the
multi-channel audio feature can be enabled. Figure 23 shows the back panel audio
