I use Audacity to record the Line In of my Audigy 2 ZS. The Audacity web site has a nice wiki guide that will help you with setup.

Thanks very much. I've just downloaded it. I ran it, and attempted to make a recording, but I get complete silence. But I've just realised something. I've got an X-Fi gamer card. I looked up the spec on the net, and I think that all of its jacks are output only. I don't think that any of the 3.5mm jacks are inputs. No wonder I've never been able to record on this card - that's if I'm right about the jacks. There's another jack on the back, with a weird kind of pink glow coming from it. I don't think I can plug the 3.5mm audio cable in to it.

The last (white) one is a dual Flexijack which features line in, microphone in and optical out.

Apparently you need to configure that white jack for line-in.

Solved! Thanks very much, that's perfect. I have it working. Damn I'm stupid!

swaaye: please explain in layman terms, what you mean by configure. Cause I have an XFI Xtreme gamer soundcard, and I am using the microphone part , when I am using skype. And I record normally via the microphone, so how do I configure it ? or do I have an "older" version of that card ? cause I bought the card 2 or 3 years ago.. Or are we basically talking about, you can not plug a jack to jack stick to it, and record from the "source" which in this case could be another sound card or a stereo system ? sorry if I sound confused. Even though I do not intend to be confused. Or does it need some kind of pre amplification as a "Middleman" between the source and the card ?
