I see that some games indicate that they are formatted in Dolby Digital. I'm thinking of a setting up my kid's game room with surround sound speakers . I note that one can buy cheap PC speakers with a sub-woofer that also are marketed as "game system" surround sound speakers. Question: How do they hook up to a Gamecube or Play Station II? The Curcuit City salesperson told me that I need a optical digital cable. That doesnt make sense to me in that the speakers designed primarily for PC suuround sound, usually do not have optical digital connectors. So, how do I get surround sound with PC-type speakers and a game system? Andy.
