No, I do not see a wave form , and, the audio does not play at all. I tried to have the video/audio play separately, from within the media viewer, but still no audio. I'm wondering if the webcam capture picked up the audio in the first palce, even though I don't know why it wouldn't.
Here, shortly, I think I'll try to "capture" some web-cam video again to test it.
