Using the Mac Pro integrated microphone in VirtualBox Windows XP Host?

Is it possible to use the integrated microphone that comes with the Mac Book Pro inside Virtual Box with Windows XP Host? Because I tried and the only thing I get is noise.


Latest information I found about this topic is from September this year and it seems not to be possible:

Sorry still no support for audio in on osx. You might be able to use an external usb sound card for input but no guarantees at all. Oh and then you must use the puel-version to get usb at all.
