[Openal] Capture problems under Windows

That is expected behaviour.   The "Generic Hardware" and "Generic Software"
are playback devices only.  For capture devices, OpenAL enumerates all the
audio input devices on the system.

Are you calling alcCaptureStart() ?  You didn't include all the code so
perhaps you do this somewhere else ... but just in case!

Could you try modifying the Capture example code that came with the SDK to
use the same settings as your code (e.g buffer frequency, sample size, etc
...) and see if that works?
