Here's a pointer from a lesson learned the hardway. I could not get audio in my "Voice Response Debugging Window" (the VRDW) after struggling with it for a long time I finally figured out my laptop had two speaker/microphone devices installed, the first a bluetooth headset and second the internal speaker/micorphone. When I started a debug session the VRDW was using the bluetooth headset (which I don't own). After I disabled the headset the VRDW worked properly using the internal speaker and microphone.
