Maybe...   just make a voltage divider with a couple of resistors.

However, it may not be necessary.  Lots of sound cards, including many 
built in laptop computers, can be configured as  a LINE-IN device, OR as 
a MICrophone device, within the software drivers.   Most Creative SB 
cards work this way - you activate the same input as either a mic or 
line-in jack in Windows Volume Mixer.

Yours may work this way.   If so, you just set it thus, and hook it up.

If not, then post back and either I or one of the other guys will 
describe how to make a voltage divider - I build them as part of making 
electret computer microphones match dynamic mic inputs on transceivers. 
   Easy.

OR... you can buy an attenuator cable.   I used to buy them at 
RadioCrack.  Not sure, but I suspect they still sell them.
