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.

S/PDIF out:

The S/PDIF out jacks can transmit audio signals to an external decoder for decoding to get the best

audio quality. Install the S/PDIF in and out cable first if you want to output S/PDIF digital audio signals

to an external decoder.

A. Installing the S/PDIF Out Cable:

Step 1:

First, attach the connector at the end of the cable to the SPDIF_O

header on your motherboard.

Pin 1 (the red wire) of the S/PDIF out cable must align

with pin 1 of the SPDIF_O header. Incorrect connection

may render the device unusable or even result in

damage to the device.

Step 2:

Secure the metal bracket to the chassis back panel with a

screw.

5-2 Troubleshooting

5-2-1 Frequently Asked Questions

To read more FAQs for your motherboard, please go to the Support\Motherboard\FAQ page on

GIGABYTE's website.

Q:In the BIOS Setup program, why are some BIOS options missing?

A: Some advanced options are hidden in the BIOS Setup program. Press <Delete> to enter BIOS Setup

during the POST. In the Main Menu, press <Ctrl>+<F1> to show the advanced options.

Q:Why is the light of my keyboard/optical mouse still on after the computer shuts down?

A:Some motherboard provides a small amount of standby power after the computer shuts down and

that's why the light is still on.

Q:How do I clear the CMOS values?

A: If your motherboard has a clearing CMOS jumper, refer to the instructions on the CLR_CMOS jumper

in Chapter 1 to short the jumper to clear the CMOS values. If your board doesn't have this jumper,

refer to the instructions on the motherboard battery in Chapter 1. You can temporarily remove the

battery from the battery holder to stop supplying power to the CMOS, which will clear the CMOS

values after about one minute. Refer to the steps below:

Steps:

1. Turn off your computer and unplug the power cord.

2. Gently remove the battery from the battery holder and wait for one minute.

(Or use a metal object like a screwdriver to touch the positive and negative terminals of the battery

holder, making them short for 5 seconds.)

3. Replace the battery.

4. Plug in the power cord and restart your computer.

5. Press <Delete> to enter BIOS Setup. Select "Load Fail-Safe Defaults" (or "Load Optimized Defaults")

to load BIOS default settings.

6. Saves changes and exit BIOS Setup (select "Save & Exit Setup") to restart your computer.

Q:Why do I still get a weak sound even though I have turned my speaker to the maximum volume?

A: Make sure your speaker is equipped with an internal amplifier. If not, try a speaker with power/

amplifier.

Q:What do the beeps emitted during the POST mean?

A: The following Award BIOS beep code descriptions may help you identify possible computer problems.

(For reference only.)

1 short: System boots successfully

2 short: CMOS setting error

1 long, 1 short: Memory or motherboard error

1 long, 2 short: Monitor or graphics card error

1 long, 3 short: Keyboard error

1 long, 9 short: BIOS ROM error

Continuous long beeps: Graphics card not inserted properly

Continuous short beeps: Power error
