Asus P5E-V HDMI - Manual (Page 60)

2-34 Chapter 2: Hardware information
8. Optical drive audio connector (4-pin CD)
These connectors allow you to receive stereo audio input from sound sources
such as a CD-ROM, TV tuner, or MPEG card.
Never connect a USB cable to the IEEE 1394a connector. Doing so will damage
the motherboard!
You can connect the front panel 1394 cable to the ASUS Q-Connector (1394,
red) first, and then install the Q-Connector (1394) to the 1394 connector
onboard if your chassis supports front panel 1394 ports.
