I'm not quite sure what you are talking about, but I'll give it a try. You will have a least a "audio out" or "line out" plug on the back of you're computer. I think you are saying you want to use something other than a computer speaker system, if this is the case, you will need a stereo mini plug adapter that y's to two RCA type plugs, these will then need to go from your computer to an input on an external amp, you will then need to hook your speakers up to the amp. If this is not what you have in mind, let us know. Depending on what features you need, if you just want stereo sound, and no effects, you don't need a specific sound card.
