FAQ and Trouble-Shooting
This section provides some tips to troubleshoot the sound card.
What are the Configuration Problems?
What are DMA channels and PCI?
The SF256-PCP PCI sound card has been functioning fine and
well. After adding some new devices to your computer, you are
puzzled why it stops working. Sometimes you may experience
similar situation when you replace your fax-modem card. There
maybe a conflict between the sound card and the fax-modem card
(such as I/O address or IRQ). Often, other problems are extermely
simple: poor cable connections etc. Check the obvious first, not
What are the Configuration Problems?
Adding new hardware and software to your computer requires no
conflicts existing devices in the system. If you have difficulty with
the installation procedure or are unable to make the card work, a
conflict may be present. The section provides the sound card's
resources information.
Even though the SF256-PCP PCI sound card is a Plug-and-Play
card, the presence of other legacy cards can still cause resource
FAQ and Trouble-Shooting
To resolve such conflicts, it is important to know the settings of
other cards and peripherals currently in your system, including the
mouse, fax-modem, video accelerators, etc. For detail information,
refer to the section on Resolving I/O conflicts.
There are three major configuration settings to consider:
a. I/O Port Address,
b. Interrupt Request line (IRQ),
c. Direct Memory Access channels (DMA)
Generally, you will only have a DMA conflict if your system
contains another sound card or an external CD-ROM drive. To
verify resource conflict, refer to "Resolving Hardware conflicts
under Windows 95/98" on page 5 within this chapter.
Understanding SB System Resource
SF256-PCP PCI sound card's Legacy Audio refer to SB legacy

Determine System Resources
To find out your SB16 legacy resources in Windows 95/98. Do the
1. Click on the Start button from the taskbar, select Settings
and then click on Control Panel.
2. Double-click on the System icon.
3. In the System Properties dialog box, click on the Device
Manager tab.
4. Double-click on SF256-PCP Legacy component, and then
double-click on the Resource tab.
You can use the information in the resource list to help you to
configure MS-DOS games using your sound card.
FAQ and Trouble-Shooting
The resource list shows three I/O address range entries, one DMA
entry and one IRQ entry.
Some old games have difficulty detecting the PCI audio card at
certain resource settings. as the game developer expects the PCI
card to be fixed at a set of resources and would fail to load if those
resources are not detected. If you are running older MS-DOS
games that do not work properly, try changing the PCI audio
legacy's configuration.
Most MS-DOS based games that provide sound have some
procedure for audio setup. These procedures generally present a
list of popular audio card or audio device.
Resolve I/O Resource Conflicts
Conflicts between your audio card and other peripheral device
may occur if your card and another device are using the same I/O
address range.
To resolve I/O address conflicts, change the resource setting of
your audio card or the conflicting peripheral device in your system
using the Device Manager under Windows 95/98.
If you still do not know which card is causing the conflict, remove
all cards except the sound card and other essential card (for
example, disk controller and graphics cards). Next, add each card
back one at a time until Device Manager indicates that a conflict
has occured. This way you will know which card causes the
conflict with your audio card.

FAQ and Trouble-Shooting
What are DMA Channels and PCI?
Under Windows 9x, the SF256-PCP PCI Sound card is capable of
full duplex audio. This means that the card can playback WAV file
and record another WAV file concurrently. With the PCI bus, full
duplex is possible without any DMA channels.
To test full-duplex yourself, try the following steps:
1. Launch the Sound Recorder as shown below:
2. Launch another session of Sound Recorder.
3. Use one of the Sound Recorder to play any WAV file (select
a long WAV file).
4. Use the other Sound Recorder to record your voice through
a microphone.
5. If both works, your sound card support full-duplex.
There is no microphone support in the MS-DOS Mode and
therefore only a single DMA is required for legacy emulation.
User Manual
Problems with Joystick and Games
What should I do if my joystick does not work?
1. The audio card's joystick port may conflict with the system's
joystick port. Disable the audio card's joystick port and use
the system port instead. Refer Install Joystick under chapter
4 if you are using Windows NT.
2. If you are having a problem with external joystick or game
port, make sure that the Joystick is enabled and the
Windows 9x Gameport Joystick drivers are loaded and
working properly in the Device Manager. You can test your
joystick by clicking on Game controller icon in the
Control Panel.
3. In order to use two joysticks, you will need to use a
SoundBlaster-compatible Y-connector (such as Radio
Shack part # 26-380), or use an industry-standard MIDI
Joystick kit. This will make allowances for the proper direct
connections for dua joysticks.
What should I do if I have problem with playing games?
Make sure that you have the game set up in a music option that the
SF256-PCP PCI sound card supports i.e. use SF256-PCP
Internal FM in the Multimedia properties' MIDI tab. If your
game takes advantage of DirectX or DirectSound be sure that you
have the latest DirectX installed.
FAQ and Trouble-Shooting
My DOS games do not work properly with SF256-PCP
PCI sound card and the system pops up the message
"Can't find PCI Chipset Device!" during system boot-up.
If your sound card does not work properly with your DOS games,
and you see the message "Can't find PCI Chipset Device!" when
the system is executing CFG801.EXE in AUTOEXEC.BAT, open
the file C:\AUTOEXEC.BAT to check if there is one line which
states "C:\CFG801". If this line does not exist, it means the driver
is not installed properly.
Please re-install the SF256-PCP audio driver again. Double-check
and make sure that the AUTOEXEC.BAT file have the following
Problems With My Sound Card
Can I install two sound cards?
Having another sound card in your system in addition to the
SF256-PCP PCI Sound card will greatly increase the chances of
having system conflicts. We highly recommended that any other
sound devices and their associated Windows drivers be removed
before installing the SF256-PCP PCI Sound card.
Does SF256-PCP support Linux OS?
SF256-PCP PCI sound card supports Windows 95, Windows 98,
Windows NT 4.0 and DOS. Linux is not supported.
User Manual
Why are some of the Windows Multimedia Components
(i.e. Media Player) are missing?
If you install the SF256-PCP PCI sound card after Windows 9x is
installed, Windows will not install the sound utilities that you
would expect to find. Features such as the Audio CODEC, the
Media Player, and the Microsoft Mixer may not be present. This
may cause your sound card not to function properly, even when
the drivers are installed. If this is the case, these applications must
be installed onto the system from the Windows 9x installation CD.
I have bought the sound card with Yamaha software
Wavetable synthesizer in the package. But I can not
install Yamaha Wavetable synthesizer in my computer.
You need to install SF256-PCP PCI sound card driver first before
you install Yamaha SoftSynthesizer. Refer Chapter 3 to install
SF256-PCP PCI Sound card driver in Windows 9x or Chapter 4 in
Windows NT4.0. Refer Chapter 5 Installing Yamaha
Softsynthesizer Application to install the Yamaha Wavetable. The
Yamaha 256 SoftSynthesizer for Windows NT is currently not
available yet.
Yamaha soft-synthesizer or Games performance
is slow or there are intermediate pauses.
There is insufficient memory to run Yamaha soft-synthesizer or
some game. Increase memory if you encounter system slow down
when you run games or Yamaha soft-synthesizer. Since the sound
card is HSP (host-based processing), it requires enough memory to
allocate the wavetable samples bank. It is recommended to run the
application in a 32MB RAM system. If you still experience games
performance degrading, turn off the Yamaha driver.
FAQ and Trouble-Shooting
Why are two interrupts allocated for my SF256-PCP
sound card?
The PCI audio uses one PCI interrupt for operation. Additional
IRQ is used for ISA legacy support.
One PCI IRQ is needed for the audio to function under a PnP
operating systems such as Windows 9x. An additional ISA IRQ is
dedicated for legacy audio support. Legacy audio support is used
for DOS based applications and games that are SoundBlaster
compatible. Most DOS based applications and games only use
SoundBlaster compatible legacy audio requiring the use of a ISA
IRQ. By disabling the ISA legacy audio support in the operating
system the dedicated ISA IRQ is freed, thus using only one PCI
IRQ. DOS Applications and games that require SoundBlaster
Audio support will have no audio output if ISA legacy audio is
Another way to save one IRQ is to make the BIOS assign IRQ5 or
IRQ7 or IRQ9 to SF256-PCP PCI Audio. This way, ISA legacy
audio can also be supportd via SF256-PCP PCI Audio. Please
refer to the BIOS user manual of your motherboard to see the
details on how to allocate the IRQ to PCI slots.
What happened if my SF256-PCP sound card and driver
are both properly installed, yet, there is still no sound?
If the SF256-PCP PCI Sound card drivers are properly installed
with no conflicts, yet there is no sound, the problem may be with
your audio connections. Here are some suggestions:
1. Try playing both WAV file and MID file to ascertain that
there is no sound at all coming from the speakers. If you
hear one and not the other, the problem is internal and has
nothing to do with your audio system.
2. Be sure that your speakers system is properly set up. Try
connecting a sound source CD audio player other than
SF256-PCP and establishing whether or not you can hear it.
User Manual
Refer Chapter 2 Setting Up SF256-PCP Sound Board to
check on the speakers connection.
3. To eliminate the possibility of a bad cable, try plugging a
pair of high impedance headphones to the SF256-PCP PCI
sound card's Front Speaker jack or Rear Speaker jack and
see if you can hear any sound.
My speakers system has no problem, but there is no
Audio output when playing digital files such as WAV,
MIDI files or AVI clips.
Check through the following possible causes:
1. You may be using a pair of passive speaker. This sound card
does not work on passive speakers. You need to use active
speakers or external powered speakers.
2. The external amplifier speakers' volume control knob is at
minimum. Turn your external powered speakers' volume
control knob to mid-range.
3. The external amplifier speakers maybe connected to the
wrong jack. You need to check and ensure that they not
connected to Line-In jack or Mic jack or Antenna jack (on
model SF256-PCP-R).
4. You may have connected your external powered speakers to
the Rear Speakers jack and have selected dual speaker
mode in the Q3D control panel. Remove the jack and
connect it to the Front Speaker jack and unmute the Front
speaker volume and Master Volume.
5. There could be a hardware resources conflict. Refer to the
section on "Resolving I/O Resource conflicts".
FAQ and Trouble-Shooting
How do I change volume and balance levels under
Windows 9x?
To make adjustments to SF256-PCP PCI sound card's volume
settings and balance levels, use the EzAudio Rack Mixer. The
Install Wizard adds the EzAudio icon to your taskbar. Click on the
EzAudio icon and the EzAudio Rack pop-up on the screen.
Double-click on the Mixer button and the Volume control window
pop-up on the screen. You can adjust the volume bar up and down,
or adjust the balance bar left and right. Adjust the Front Master
and Rear Master to set your own preference of mixing front and
rear speakers system, this add some difference in your surround
My sound card works but there is no sound when playing
CD-audio or when playing DOS games that required a
CD-ROM drive.
1. Be sure that your CD volume is turned up to the maximum
in the volume control of the Mixer. If you hear no sound
from CD-audio, you need to verify that the internal audio
cable is connected between your CD-ROM drive and the
sound card's CD header, J3 or J4. This is typically a small
connector with three or four wires coming out of it. Refer
Chapter 1 for connectors information.
2. Another tip is to obtain a 1/8" stereo patch cord and connect
one end to the "headphone out" on the front of the CDROM drive, and the other end to the Line Input on the back
of the sound card. Make sure the headphone volume dial on
the CD-ROM drive is at maximum, and try playing a CD
audio track. You should hear the music playing. If your
internal patch cable is missing or defective, contact your
CD-ROM manufacturer for information on how to obtain
another cable.

FAQ and Trouble-Shooting
Experience choppiness in Netmeeting or InternetPhone
or other 3rd party conferencing software when you do
video conferencing.
If you experience choppiness in Netmeeting or Internet Phone, the
followings may be the possible cause:
1. Check the modem connection.
You need to check whether your modem connection speed
has dropped, or the modem connection speed at the other
end may be low. Your connection will depend on your ISP
(Internet Service Provider). Busy traffic during peak hours
may reduce the connection speed.
2. Check whether full-duplex audio is enabled.
If you use Internet Phone and have enabled your sound
card's full-duplex option, you can listen and talk at the same
time (e.g. standard telephone conversation). In order for you
to do this, the person that you are talking with also needs to
have a full-duplex card. Otherwise, you will experience
intermediate pauses during conversation.
If the other person uses a half-duplex sound card, you must
wait for the other person to stop talking before you can talk
(e.g. talking on walkie-talkie).
3. Check other application driver is enabled.
If you had installed Yamaha SoftSynthesizer, check that
your sampling rate is not at 44KHz. It is recommended to
use 22KHz sample rate for video conferencing. Otherwise,
disable the Yamaha SoftSynthesizer driver. Reboot the
system for the changes to take effect. This will improved
any choppiness.
4. Check Video is enabled.
If you have setup a video camera together with your audio
card, you will experience choppiness because more data are
being sent out to the network (internet).
