I just bought a new pair of speakers.. The logitech x-530's. I have an image g5. I just realized i dont have all of the connections that i guess these speakers need. I had a good set of speakers before, with four speakers and a sub woofer and they all worked. Now only certain speakers work depending on which colored jack i put into my computer. Is there an adapter i can buy to make the orange, yellow, and black jack fit into my computer, enabling the use of all 5 speakers?
