[Openal] Could not find capture device

For either the "Generic Hardware" or "Generic Software" devices, the 
following call should always return ALC_TRUE:

alcIsExtensionPresent(Device, "ALC_EXT_CAPTURE");

If you are using a1.1-compliant version of the wrapper (it seems like 
you are), then getting ALC_FALSE back should be impossible (make sure 
you're calling "alcIsExtensionPresent" instead of "alIsExtensionPresent" 
-- that's an easy mistake to make, but a hard one to see).  The file 
"wrap_oal.dll" in your system directory should be at version 2.0.8 if 
you have the latest version installed.

That is correct -- you want to also enumerate the available capture 
device names (ask for ALC_CAPTURE_DEVICE_SPECIFIER or 
ALC_CAPTURE_DEFAULT_DEVICE_SPECIFIER) and use one of them ("MMSYSTEM" 
will be what comes back, but your code might as well ask rather than 
assume so...).  When you open "MMSYSTEM" it should work...
