How to make an audio system in a room?

Question

3D

My parents built a house and gave me a separate room. It turned out that everything inside it will do itself. So, I would like to organize the sound output from the working machine (computer) via four channels (front left, front right, back left, back right). Can it be done?
As I understand it, you need to buy an audio card (4 channels). Maybe you can configure the channels programmatically?

On modern (in 2007 it was already on budget) motherboards, it is often possible to replace the line input with an output for the side ones in the drivers, the usual output becomes for the front ones.
