How do screen video capture apps record audio?

    Trying to get to the bottom of a problem with MSI Afterburner in
    capturing online game play.

    XP Pro SP3, Audigy Platinum ES audio. I made some test captures of
    online gameplay. I find it only captured the audio in mono. It's
    supposed to do it in stereo. Tried various settings. I was getting
    stereo capturing the home screen which has some audio background but
    once it got to the level of gameplay, only mono. There are plenty of
    examples of Afterburner capturing stereo audio on YouTube.

    Normally I have the onboard audio disabled but for purposes of
    experimentation I re-enabled the Azalia audio in bios, loaded the
    Realtek drivers. The Audigy is still installed but I have the Realtek
    audio selected as the default within Windows and specified within

    Now, I get *no* audio with any captures including Youtube. Captures
    video fine but not the audio. Un/Re-installed MSI Afterburner, even
    tried the newest beta version. Audio through the speakers is fine. So
    apparently the screen cap app isn't connecting with the audio.

    Anyone have any insights?

    I've got audio recording - had to unmute the "Stereo Mix" selection in
    the Realtek mixer but I'm getting the same behavior as with the
    Audigy. I get stereo audio at the point of the home screen but only
    mono audio within the game. Stereo Youtube video records as stereo.

    I have to modify this yet again. If I start recording while I'm still
    on the main screen, I get stereo, if I wait until I'm in game, I get
    mono audio.
