This explains how to install one or more AudioScience adapters in a Windows based computer.

Setting Adapter Index – One Adapter in the PC

1. Make sure your computer is turned off.


2. PCI adapters should be installed in any empty PCI slot and PCIe adapters should be installed in any x1 (or greater) PCIe slot.


3. Make sure the adapter jumper is set to adapter index #1, the factory default.  For a new card no changes need to be made.  For an AudioScience adapter from another installation, check that it is set to adapter index #1.


Depending on the adapter family, there are different ways of setting the adapter index.


Adapter Index switch set to Adapter #1

For ASI5300, ASI6300, ASI8700, and ASI8900 families, there is a rotary switch.


NOTE: Position 0 (zero) represents adapter #1, position 1 is adapter #2, etc.

For ASI5000 and ASI6000 families, there is an adapter jumper that must be set.  The left most position represents adapter index #1.  

Adapter Jumper set to Adapter #1


 4. Turn on the computer and let it boot.  Under Windows, a dialog box will pop up informing you that the computer has detected a new Multimedia Audio card.  Cancel out of this dialog box and proceed to the software installation section of this datasheet.

Setting Adapter Index - Two or More Adapters in the PC

1. Make sure your computer is turned off.


2. PCI adapters should be installed in any empty PCI slots and PCIe adapters should be installed in any x1 (or greater) PCIe slots.  Different adapter types can coexist in the same computer; for example, an ASI6416 and ASI8921 will work correctly if installed in the same PC. Different adapter types still require unique adapter index numbers.


3. Each adapter in the PC needs to have its adapter jumper/rotary switch position set to unique numbers.  For example if you are installing two adapters, the first one would be set to adapter index #1 and the second to adapter index #2.


  1. For ASI5000 and ASI6000 families, the position to the right of index #1, when jumpered, represents adapter index #2.  The next position represents #3, and the rightmost position, when jumpered, represents #4.
  2. For ASI5300, ASI6300, ASI8700, and ASI8900 families, rotate the rotary switch to indicate what position is required.



AudioScience makes audio adapters and drivers for various operating systems. Enhancements to an adapter’s utility come from the integrators software that uses the audio driver to implement sophisticated audio playback and recording functions.

Drivers for Windows 10, 7, Server 2008, Server 2012

Typically, drivers are not included with the hardware and will need to be downloaded from the AudioScience website. They can be found here: http://www.audioscience.com/internet/download/win_drivers.htm


The first step is to determine what type of driver is needed for your operating system.  Drivers are available for 32-bit and 64-bit Windows systems. 


Driver 3.10 and later present the user with three install options during installation:

  • Install Standard PCI/PCIe Driver.
  • Install Standard + Network Audio Driver.
  • Remove all driver components

Traditional installs should select the first of these options. Users of AudioScience CobraNet and AVB products should select the second option with the “+Network Audio Driver.” in the text.

Combo Driver

The Combo driver installs WDM devices by default and presents an option to “Install legacy 32-bit WAVE driver” in case your application requires it. Download the file named ASICOMBO_xxxxxx.EXE from www.audioscience.com and run it (_xxxxxx is the version number). After the EXE has run, reboot your computer and the audio adapter will be operational. If the cover is off the computer, one can see one or two blinking LEDs on top of the card indicating its DSP is running and communicating with the driver.


Verify that the adapter is running using ASIControl (see ASIControl section in this document).


All AudioScience drivers also install an ASIO driver interface. It is installed by default.

Driver Failure

In the event that an adapter’s driver fails to load correctly, the OS’s event viewer should be checked. The event log is accessed from the Administrative Tools applet in Windows Control Panel under Event Viewer. The Windows Logs\System view should be selected.


If two or more adapters are installed in the same system, the first thing to check is that the adapters were assigned unique adapter numbers. If issues persist, please email support@audioscience.com.
