Basically I'm recording with either reaper or audacity but none of them work well. I use a line 6 spider III amp with a distortion pedal and when i link the computer to the the amp via a cable and an adaptor going into the amp it picks up sound with reaper, but its about a second delayed and when i try with audacity it doesn't pick up anything at all.

I've tried changing the record input and output status in preferences with audacity and doesn't work at all.

Any ideas?
Are you sure you're plugging into the mic slot?
Also on Audacity is the drop down menu next to "input volume" set to "Microphone"?
