Hello: I just joined this list to find a solution. My wife has Windows XP, Jaws 10 and the Alve BC 640. When the BC 640 connects, the voice goes to it and she can barely hear it. It used to have the sound on the computer and the BC 640 had the braille. Since reinstalling the BC 640, the sound is on the BC 640. How do we get the voice back to the computer. If the BC 640 is off, the voice is on the computer. Thanks Bob
