How do I Hook up my PS3 to Samsung surround and Philips LCD? - philips lcd wall mount

Ok, I have a 42 inch Philips LCD and a PS3 via HDMI cable connected and gave me a new Samsung surround sound system is connected via an HDMI cable ... but I know how to get the surround sound system connected to the place where I can get the effect at play or a film with my PS3? Any help or advice is appreciated. I know I must have a digital optical cable, but I'm not sure how to do it.
