well, if it has an actual jack, use that. I didn't realize that you were using a laptop. The only problem might be that the conversion might come out mono. Usually a mic jack is not setup to be stereo. (manufacturer decision) it might be, but might not too.

I suggested line-in cause alot of people use the mic jack for a microphone for web chatting. But it will work the same. Use just have to make sure Goldwave or whatever wav editor you use is set to record on the microphone.

Hoping for the best. Good luck.
