alGetError works on the current context. However, capture devices don't use a 
context. Without a context, alGetError will always return 
AL_INVALID_OPERATION because it is an invalid operation to use the regular 
al* calls without a context set.

Instead, you need to use the alc* function with the capture device. 
alcGetError(mydevice) should return the proper error code.
