ule which is required for digital output. The SPDIF
Out module includes an optical SPDIF Out jack and
a coaxial SPDIF Out jack. Follow the steps below
to enable digital output support.
Step 1. Connect SPDIF Out module connector to
the SPDIF_IO connector on the
motherboard.

English4-1-6DTS Introduction
1. Introduction
In a continuous effort to bring the finest cinematic surround effects to the consumers, Creative has
partnered with DTS, Inc to integrate DTS-ES and DTS-Neo:6 into their Sound Blaster line of audio
products. This paper will discuss the benefits of having these technologies and how to bring the ultimate
entertainment experience out of them via the Creative software applications.
2. DTS-ES
A new encoding scheme adopted by DTS that provides realistic home theatre experience through
discrete 6.1 channel extended surround sound while still maintaining compatibility with existing 5.1
systems. This new DTS Extended Surround bitstream is available for DTS-encoded content on all
media (CD, LD and DVD-Video) whenever the multichannel recordings are discretely mixed in 6.1.
Audio data can be decoded through either an external decoder or now, Creative built-in decoder.
When using a DVD-Video disc encoded with DTS-ES content, the audio mode has to be set to this format
before playback begins. The setting is usually in the Main Menu Audio Setup section that will automati-
cally be displayed when the disc is inserted.
2.1 Using Creative Built-in decoder
Step 1: Device Control
One of the most recent audio products that incorporate DTS technology is the Sound Blaster Live! 24-
bit integrated on motherboards. Device Control is the control application that handles the decoding. 
						

							GA-G1975X-C Motherboard - 94 -
English
By default, the on-board Creative audio device provides the decoding. The Use Installed Decoder
option will be checked.
When a 7.1 speaker system is used, a 4-channel or 6-channel audio content can be mapped to the
additional speakers. Default is a map to the side speakers.
The Creative configuration is completed once the Creative Speaker Settings is set to 6.1 or 7.1 speaker
mode.

EnglishStep 2: Configuring 3rd party SoftDVD players
All softDVD players typically have a option to use SPDIF OUT. This option needs to be turned on in
conjunction with the Creative settings above for the built-in decoder feature to work. Examples using
WinDVD and PowerDVD are illustrated below.

2.2 Using External Decoder
In  a case whereby an external hardware decoder (e/g DTS Home Theatre System) is used, the option
to use SPDIF Passthrough is to be checked. Encoded audio data will pass through Creative driver
without decoding. 
						

							Appendix - 97 -
English2.3 Decoding using SoftDVD player
A softDVD player which supports multi-channel playback offers an alternative option to external
hardware decoding. Select a 8-channel playback option if a 7.1 speaker system is used. Examples
using WinDVD and PowerDVD are illustrated below.

3. DTS Neo:6
Integrated into Creatives full-featured media player Creative MediaSource, DTS Neo:6 Settings en-
ables users with 5.1 or 6.1 speaker systems to derive five or six full-band channels of audio from two-
channel matrix-encoded sources. The result is a richer and more natural aural experience, a luxury
that owners of discrete multichannel systems have increasingly come to expect.
DTS Neo:6 Settings features two modes:
zMusic Mode: Expands stereo non-matrix recordings into five or six channel layouts without
diminishing the subtlety and integrity of the original stereo recording. It is designed to enhance
the playback of two-channel music recordings such as Compact Discs (CDs) and stereo
audio files through 5.1 or 6.1 speaker systems.
zCinema Mode: Decodes extended surround matrix soundtracks optimally. It is designed to
enhance the playback of matrix-encoded movie content through 5.1 or 6.1 speaker systems.
Note that DTS Neo:6 Settings only works in conjunction with Creative MediaSource Player and this
technology is effective on two-channel content only. It will not have an effect on content that is mono or
that has more than two channels. DTS Neo:6 Settings can only be launched from within Creative
MediaSource Player/Organizer.
3.1 Launching DTS Neo:6 Settings
To launch DTS Neo:6 Settings:
1. Launch Creative MediaSource Player/Organizer.
2. On the Menu bar, click Tools -> DTS Neo:6 Settings.
3. DTS Neo:6 Settings appears. 
						

							Appendix - 99 -
EnglishThe DTS Neo:6 is located under the time display area in Creative MediaSource Player (version 2.02
and above). It is circled in red below:
Neo:6 Mus indicates that Music Mode is enabled while Neo:6 Cin indicates that Cinema Mode is
enabled. Note that changes to DTS Neo:6 settings will not take effect on the track that is currently in
play. The changes will only take effect from the next track onwards.
4. Final Word
Neo:6 will be featured with DTS-ES in a Creative audio system that is lined up to include DTS
technologies. Together, they offer both discrete and matrix decoding that will help to bring the best audio
experience out of a Sound Blaster.

4-2 Troubleshooting
Below is a collection of general asked questions. To check general asked questions based on a specific
motherboard model, please log on to http://www.gigabyte.com.tw
Question 1: I cannot see some options that were included in previous BIOS after updating BIOS. Why?
Answer: Some advanced options are hidden in new BIOS version. Please press Ctrl and F1 keys after
entering BIOS menu and you will be able to see these options.
Questions 2: Why is the light of my keyboard/optical mouse still on after computer shuts down?
Answer: In some boards, a small amount of electricity is kept on standby after computer shuts down and
thats why the light is still on.
Question 3: How do I clear CMOS?
Answer: If your board has a Clear CMOS jumper, please refer to the Clear CMOS steps in the manual. If your
board doesnt have such jumper, you can take off the on-board battery to leak voltage to clear CMOS.
Please refer to the steps below:
Steps:
1. Turn off power.
2.  Disconnect the power cord from MB.
3. Take out the battery gently and put it aside for about 10 minutes (Or you can use a  metal object to
connect the positive and negative pins in the battery holder to makethem short for one minute).
4. Re-insert the battery to the battery holder.
5. Connect power cord to MB again and turn on power.
6. Press Del to enter BIOS and load Fail-Safe Defaults(or load Optimized Defaults).
7. Save changes and reboot the system.
Question 4: Why do I still get a weak sound after turning up the speaker to the maximum volume?
Answer: Please make sure the speaker you are using is equipped with an internal amplifier. If not, please
change another speaker with power/amplifier and try again later.
Question 5: Sometimes I hear different continuous beeps from computer after system boots up. What do
these beeps usually stand for?
Answer: The beep codes below may help you identify the possible computer problems. However, they are
only for reference purposes. The situations might differ from case to case.
