Where did you connect the audio cable to on the camera? Having an audio out port does not neccessarily mean that there is audio on that
Did you have your cam connected to the TV once? Was ther audio from this port on your cam?
It may be that your system is not set up to accept any sound from that card either. Check in Control Panel > Sounds and Audio Devices > Audio Tab which device is listed there for recording.

Make sure your capture device is listed there. If not, select your sound card and use the line in to connect your cam.
