Usually you would do this hook up in the audio program you're using.

What audio program are you using?
Sometimes it's done through the audio card's hardware mixer. What sound

hardware does your laptop have?
Of course, maybe mono is all it has for an input. My laptop's built-in

audio has only one external input: microphone. I know from experience

it's mono (not stereo). It's intended for mic input for computer

telephony or computer gaming headsets, not recording stereo.
My Behringer UCA-202 shows me two inputs in Rosegarden. By default,

Rosegarden sees them as stereo. If I tell it to see the instrument as

mono, I get to pick left or right channel. So I can hook the left

channel to one track and the right channel to another, or both channels

to the same track as stereo.
I don't have any real pro audio card here, and don't really do much with

audio programs beyond a bit of mixing in Audacity, which some here don't

consider a pro audio program ;-). That's why I'm hoping someone else on

the list can chime in!
