I just bought a house (new to me) with a built in surround sound system. I can not figure out how to hook this thing up. It has 5 speakers and appears to have a different set of wall plugs for each speaker. My TV has two audio out ports. (Not the same type of plug for either: one says digital and one is a single black square that says audio out). The surround ports (2 for each speaker) are gold with a red stripe and a black stripe. I have no clue. Thanks for your help!
