My TV only has a DVI connection and no HDMI connection so I use and HDMI cable with an HDMI/DVI adapter to hook up TV. I then use two RCA audio cables for sound. If your surround sounds uses RCA cables for input, you should be okay. It all depends on what format of input it will take. It does have a digital audio output port that looks like it takes an RCA cable. I would assume it works it the two RCA audio ports work.
I think you want the tv, blu-ray and surround sound all hooked up together? You should be able to use the hdmi between the blu-ray to the tv which will give you the 1080 picture, then either a digital (optical) audio cord or a coaxial audio cable (orange) from the tv to the surround sound. If your TV has a second hdmi port and your surround has a hdmi port as well, just use a second hdmi cord.
I think so but you would only be getting your surround sound system's sound when playing your blu ray player. Therefore you would still be using your TV's speakers for everything else. If that is what you want, I think that it will work.
depends more on your sound system than the blu-ray. as long as your sound system has the proper inputs/outputs, it should accomodate the blu-ray player. i have my blu-ray, roku, and tv running into a sound bar via 2 hdmi cables & an optical cable, then back to the tv via an hdmi cable. your sound system probably has a similar set up.
