I think that depends on the implementation/hardware. The capture spec says 
that if the requested format (which includes sample rate, AFAIK) isn't 
available, the library will convert it before giving you the data. So if your 
device can only handle 48khz capture and you ask for 96khz, OpenAL will 
resample the data before giving it to you.

It's possible some implementations may just fail if the requested format isn't 
available, too. So probably the thing to do would be to try the "ideal" 
sample rate, and keep trying a lower value it until one opens.
