What is an ASPI driver?
An ASPI driver is required for digital audio extraction (DAE) . Windows 95 or 98 comes with the ASPI manager pre-installed, while NT does not. To tell if you have an ASPI manager installed, look for a file called WNASPI32.DLL in your Windows system directory (c:\windows\system or c:\winnt\system32 are common locations).you can download a ASPI driver from here (version 4.71)

How can I know whether the ASPI drivers are installed?
