If the noise was the same level recording without a microphone, I am out of ideas.

You can try the line in, as long as the level isn't greater than 0.1v p-p in, a divider and/or low volume should give you a signal for that.
Thanks for all the help. I really learned a lot, and it's great to have the sound card oscilloscope set up. I had done hardly anything with audio before this.

The noise does sound the same and look the same on the scope, whether recording with or without the microphone. I'll just try to deal with it by recording as loud as possible.
