Rerouting Sound Output to Microphone Input

Hi, I'm trying to use some video capture software to make movies of what's on my screen. But the audio component only accepts input from the microphone. The only microphone I have is the one built into my computer - besides, I feel like taking input from the speakers and rerouting it back to the microphone must necessarily lose SOME quality. I wondered if there was a way to reroute my sound card's output from my speakers to my microphone. That way, the video capture software can believe it's reading audio from a microphone, when it's actually just getting the audio straight from the sound card instead of the speakers. If there's software that can do this, then great. If not, I would entertain the possibility of some kind of cord, connected to both my headphone jack and my microphone jack. If you know what that would be called, I'd gladly look for it. Thanks.
Hmm.. what screen recorder software you use? Most soundcards offer the option to stream from the pc speakers. And camtasia has the option to record from these speakers.

Another option if all fails, is to record the sounds from your speakers using a good recording software such as cool edit or goldwave, simultaneously record the video (without sound obviously), then fire up VirtualDub, read in the audio and video streams you recorded, and stream the video and audio to an avi file. I know it is a pain, but it works.

Several options:

1) Fraps. If you're just wanting to record what is on your computer screen, then why not use Fraps? Fraps can record audio and video output and will make an AVI video clip once you turn it off. The only real issue I've ever had with it is the frame rate dropping sometimes. This depends on the game you're playing and your computer's speed. This method will work without you having to change any settings or purchase any additional cords and such. Plus frapping is incredibly easy. Something to check out at least.

2) If you want to redirect your sound card, I'd open up the audio headquarters under your control panel. Different sound cards allow for different features. My old sound card would allow for an internal loop (which is what you're describing). Here is how I set it up:

Click on the audio headquarters

Click properties for recording

Click on a feature that picks up sounds made from the computer. For my card it was either "What you hear" or WAV. I have no idea what card you have- so it might take some experimenting. Also you should probably turn off your mic while doing this. You don't want outside sounds bleeding in while recording sounds from this game.

Try both of those options out and see what works for you.

Thanks!
