I have Windows 7 on my MacBook using the Virtual Box program, andeverything'sfine, except I don't get any sound. It keeps telling me that no audio devices are installed, and it won't recognize the built in speakers in my laptop. It also won't recognize my headphones. Can someone please help me?

Joshua - Normally, if you're doing Boot Camp or Parallels, there are drivers found on the OSX disk. You probably need drivers supplied by Apple to get it to recognize the audio hardware. Not quite sure how Virtual Box figures into this, but one of the drivers should work.
