Disabling the microphone channel's "amplification" would only result in another line level input. And no, it's not possible....or it is, but you'd be better off not trying 
You need to use the line in on your soundcard. I know it doesn't work yet, I'm getting to that.
First of all you have to bring in enough signal. Are you running a line out from your unit? Are you SURE it's line out? Try the monitor output at a low level and see if that helps. You MUST adjust the Line Input Level from the Recording volume control. Crank it as high as it will go. And make sure it's NOT muted!
Can you monitor the sound coming in with the computer speakers or headphones? There is another volume knob for that in the Playback volume control. Often times the Line In in both the Recording and Playback controls are the same. But check it anyway, and make sure it's not muted and crank the volume up.
If you can't hear the sound coming into the computer THROUGH the computer speakers or headphones AFTER trying both of the above mentioned procedures...you have a problem. It may be that the line in on your soundcard is blown. What kind of soundcard do you have? New drivers might actually help in some cases. And cheaper soundcards will not produce good results. I used to have a cheap ESS based soundcard and all I could record with it was distortion and hum with a little bit of music in there somewhere. The signal response was horrid.
So to recap that mess...you need to verify that you do in fact have a strong signal from your source (and that your cable is good) and you need to verify that the line in port on your soundcard is working properly.
Basically, if you can't monitor what's coming in to the soundcard...and the source is producing more than enough signal...and your windows settings are correct...then you need to run down to the computer shop and pick up a new soundcard. SB PCI128 or SB/Ensoniq AudioPCI are both 30 bucks and good. The SB live is 80 bucks and pretty good.
