Hello, I wanted to post this on the forum for any users that are having trouble with the Replay Video Capture program not
recording sound. I have a Windows XP Professional using a Realtek Hd Sound card. Here is what I did to fix the issue.
Open the Realtek Hd Sound Manager and click on the "Mixer" tab at the top, make sure that the "Line Volume and the Mic Volume" speaker icons on the bottom are X-d out. Only the "Stereo Mix" speaker icon should be open (not X-d out)
Then re-open the Replay Video Capture program and go through the steps, and Voila, the video and sound record
