5-1-1 Configuring 2/4/5.1-Channel Audio

The motherboard provides three audio jacks on the back panel which support 2/4/5.1-channel(Note)audio. The picture to the right shows the default audio jack assignments.

Line In

Front Speaker Out Mic In

Audio signals will be present on both of the front and back panel audio connections simultaneously. If you want to mute the back panel audio (only supported when using an HD front panel audio module), refer to instructions on page 73.

High Definition Audio (HD Audio)

HD Audio includes multiple high quality digital-to-analog converters (DACs) that support 44.1KHz/ 48KHz/ 96KHz sampling rate. HD Audio features multistreaming capabilities that allow multiple audio streams (in and out) to be simultaneously processed. For example, users can listen to MP3 music, have an Internet chat, make a telephone call over the Internet, and etc. all at the same time.

A. Configuring Speakers:

(The following instructions use Windows XP as the example operating system.)

Step 1:

After installing the audio driver, the Audio

Manager icon will appear in your system tray.
