Audio In Plug

As you know a desktop cpu has 3 audio jack...audio in,audio out and mic...however my laptop has only 2...a mic one and a out one (the one with earphone picture)...so if i need to use the audio in jack for a external video capture...where do i place that audio cable?...my mic jack?...

thanks...

You can use the Microphone In jack, however you are going to have to play around with the Microphone Advanced sound settings so that your recorded sound isn't distorted. You may have to enable or disable Microsoft +20dB Boost.

Also, mic jacks are mono.
