The PCI 338 will provide a 360 degree positional-audio effect with headphones, or two
speakers. Four speakers are not required.
What is the difference between A3D and DirectSound3D?
Though Microsoft DirectSound supports 3D audio, there is no support for hardware
acceleration up through revision 3.0a of the DirectX specification. This means that all 3D
processing occurs on the host processor resulting in reduced game performance. A3D
supports basically the same programming interface as DirectSound3D but allows for
acceleration and enhancement of 3D Audio in hardware that supports the A3D engine.
The result is improved CPU performance and better sounding 3D audio. Full hardware
acceleration is supported in DirectSound version 5.0.
Why am I not getting CD Audio, Microphone or Windows Sounds?
Windows Volume Controls are defaulted to off when the PCI 338 is installed. Double
click on the yellow speaker on the bottom right of the task Bar. Adjust the volume
controls accordingly. To hear sound from the preferred device, make sure the Select
Box is checked. If the preferred device is not listed, go to Options then Properties, and
check the device listed under "Show the following volume controls", then click OK. To
Record, repeat the previous steps but select Recording after Options properties.
Why am I prompted for the Windows 95/98 CD when installing PCI 338?
The reason Windows 95/98 prompts you for the CD is because it needs one or more of
Windows system components that are not installed on your system. These are typically
audio components that are required when using the PCI 338. These components include
but are not limited to:
q
Joystick drivers.
q
Audio Compression modules.
q
Volume Control (Mixer).
q
Sound Recorder.
If Windows prompts you for the Windows 95/98 Installation CD:
q
Remove the PCI 338 CD from the CD-ROM drive.
q
Insert the Window 95/98 CD.
