Some video capture cards have a small squared internal audio output, to be connected to your motherboard (or to your sound card, if you use and add-in sound card instead of your motherboard’s on-board audio). This connection allows you to listed to what is being captured thru the PC speakers. Without this connection you will be able to listen to what you have captured only after playing the generated file. For this connection you will need a cable that comes with the video capture board.

Install one end of the cable on the appropriate connector on your video capture card (see Figure 8) and the other end on your motherboard, on a connector labeled “Aux In”. Look for this connector carefully, as it may be difficult to locate it, since it is usually located near or under the video card.

Some motherboards don’t have an Aux In input. In this case you have two options. Don’t make this connection – what will prevent you to hear what is being captured in real-time – or connect the cable to the CD In connector – but in this case you will lose the audio connection of your DVD burner, which may be even worse.
