If you're capturing 8-bit, then you need to store it using ALubyte 
instead of ALshort.

If the data it captures is always silence (values are all near 128), 
then check to make sure other OSX apps can properly capture audio. Make 
sure also that you've called alcCaptureStart(l_capturedevice), and that 
no errors are being generated (check alcGetError(l_capturedevice)).
