My father has a cheap emachine and I think the sound is built in. For Christmas he got some of the logitech z560 speakers. I assume that he will not be able to hook all of them up because he only has one speaker plug in the back. He does not have a front and back channel. Is this true? If so what would be a good option for him. He does not play games. I thought of a soundblaster live 5.1 because the price is only $34 online. He does not want to spend much. I just think that card might be troublesome for him. I have one and an audigy and the soundblaster messes up on my sons computer from time to time. Thanks!!!
