Recording from my soundcard only produces a low volume recording

Hello everyone. I'm trying to record stuff from my soundcard, but the recording is barely audible. My OS is Windows XP, I'm using Audacity 1.2.6 to record and my soundcard is Realtek AC97.

It is recording what's being played, just at a really, really low volume. As far as I can see, all the microphone levels are at full, but this doesn't seem to make any difference.

Any help on sorting this will be greatly appreciated.

Cheers!
