Audio Configuration

CD-ROM Audio-In Connector: CDIN
The CD-IN connector is used to attach an audio cable to audio devices
such as CD-ROMs, DVD-ROMs etc.
Front Panel Audio Header: AUDIO
If your case front panel has audio ports, you can connect them to the Front Audio Header of
this mainboard. First, you must remove the jumper caps on this header and then attach the
cables from the front panel to the pins on this header. You can use both the front audio panel
and back panel audio simultaneously. If you are not using front panel audio ports, leave the
jumper caps on the header pins (Note: pins 5-6 and 9-10) to avoid problems with the back
panel audio ports.
