V-STACK
4 – 32 Setting up your system
If you are using audio hardware with a DirectX driver (Windows only)
If your Windows audio hardware doesn’t have a specific ASIO driver,
a DirectX driver is the next best option for stand-alone use. An ASIO
DirectX driver is available with V-STACK, “ASIO DirectX Full Duplex”.
Windows 2000 users should use DirectX version 8.1.
When the ASIO DirectX Full Duplex driver is selected in the Device
Setup you can open the ASIO Control Panel and adjust the following
settings (for more details, click the Help button in the control panel):
Direct Sound Ports
In the list to the left in the window, all available Direct Sound output ports are listed. In
many cases, there will only be one port in each list. To activate or deactivate a port in the
list, click the check box in the left column.If the check box is ticked, the port is activated.
You can edit the Buffer Size and Offset settings in this list if necessary, by
double clicking on the value and typing in a new value.
In most cases the default settings will work fine. The audio buffer is used when audio
data is transferred between V-STACK and the audio card. Having a large buffer en-
sures that playback will occur without glitches. However, the time between the mo-
ment V-STACK sends out the data and when it actually reaches on the output the
"latency" will be longer.
If you are using audio hardware with a Windows Multimedia (MME)
driver (Windows only)
When you select the ASIO Multimedia Driver for the first time, the sys-
tem will ask you whether you want to test the configuration. We strongly
recommend that you perform this test. If it fails, or if you for other rea-
sons need to make adjustments to your ASIO Multimedia configuration,
click the Control Panel button to open the ASIO Multimedia Setup con-
trol panel included with V-STACK. This control panel comes with an
HTML Help describing the features and procedures.
