Here's what it looks like to me...
You're gonna need another cable for the audio. None of the connectors pictured will plug into your sound card!!!!
I don't know what you need for the camera end... You'll have to figure that out. But,
the computer-end needs a stereo mini-phone plug. This is the same connector as your soundcard's speaker connector, and the same connector thats used on portable-stereo headphones.
You should be able to find the right cable at Radio Shack, or any audio/video store... maybe even Wall-Mart.
The audio does not connect through the Belkin device. The divice has 3 connectors: USB out, S-Video-in, Composite-Video-in. You can use either the composite or S-Video input.
Traditionally -
Yellow = Video
Red = Audio Right
White (or black) = Audio Left
You do need a soundcard, but you don't need a microphone. You don't need speakers to capture the sound either... just to hear it as it's being recorded or played-back.
You don't need that red-white-black mono-to-stereo Y-adapter, unless your camera is mono. In that case, it could be used to get sound out of both speakers... If the connectors are right for your camera and the
other cable you're going to need.
The good news is, that there are not as many audio standards as video standards.
The audio signal from your camera will work with your soundcard's LINE (or AUX) input. You simply need the correct cable/connectors. There are and there are only three connector-types that you are likely to run into:
RCA (AKA Phono. Like your red-white-black cable.)
Mono mini-phone
Stereo mini-phone
How do I connect leads between camcorder and remaining single socket on Belkin device. 
Thanks in advance for all advice and ideas. PTL
so .. I dunno. It sure did cost more, but in the long run I may have saved my computer from a horrible death by hammer!
