alcIsExtensionPresent looks at whatever implementation you open.  This 
could be one of the wrapper implementations (Generic Hardware or Generic 
Software), or it could be a native implementation.

First thing to check is that you've installed the latest drivers for 
your X-Fi card.  If it can't find the native implementation (ctoal.dll), 
you'll end up with a wrapper implementation, which  you probably don't want.


Next thing is to make sure you're opening the device you think you are. 
Try this:

alcGetString(<device id>, ALC_DEVICE_SPECIFIER)

(replace <device id> with the result of the alcOpenDevice function) and 
see what device actually was opened.

Hope this helps,
