Question number two.
I am trying to see if i can set up 2 sets of speakers. One set that surrounds my PC monitor, and one set that surrounds my TV. If you take a look at the pic below, the first three circle pugs have the same symbol, yet only the 3rd one works with my pc speakers. If i plug my speakers into the first two holes i get no sound. But why wont they work if they have the same symbol? Is there a way i can go into my contol panel and get those to work too?

thanks for anyone that can help.
