Out is a connector for Speakers or Headphones. Line In is used for external CD
player, Tape player, or other audio devices. Mic is a connector for microphones.
However, there is an advanced audio application provided by Realtek ALC880
to offer support for 7.1-channel audio operation and can turn rear audio connectors
from 2-channel to 4-/5.1-/7.1- channel audio.
The mainboard also offers two SPDIF in/out connectors for stereo speaker
input/output. These connectors are used to connect SPDIF (Sony & Philips Digital
Interconnect Format) interface for digital audio transmission.
