The onboard audio CODEC can be enabled or disabled via this jumper to use an external CNR
card. Disable the onboard audio CODEC, if you want to use a PCI Sound Card or an CNR
Audio Card. When you install a CNR card, remember that the onboard audio CODEC uses the
primary channel; therefore, for the onboard CODEC to function, you must set the CNR card to be
secondary.
