I am not sure if this is possible with the hardware i have now, but if it is possible i would like to know what i need to get my desired audio setup. So i have a 50" Samsung HDTV. The sound that it produces is ok, but im wanting to have all my tv shows (especially sports) to be surround sound. I have xfinity by the way. I have a blu-ray device hooked up to the HDTV that has surround sound speakers(but only when i watch blu-rays or stream netflix off of it of course). Is there a way for me to hook up my surround sound speakers to my xfinity cable service? Do i need anymore hardware? I don't know enough about audio in order to do this, and any help is appreciated.
