hello everyone, just purchased my first macbook and its pretty sick. Now i had a desktop before with a 5.1 speaker system and would like to use that system with my mac. I have read several threads on this topic but have not gotten a clear answer. I own the new macbook so I have no firewire; cant use firewave!!!wish i could...so I want to know if there is something in the price range of the firewire that uses usb? my speaker do not support optical! WHAT CAN I DO?
