How can I connect my HDTV and playstation 3 to my surround sound?

Search Gaming or Gadget Information (i.e “Xbox 360″)

I have an Emerson HDTV which has 3 HDMI port’s, a Playstation 3 and a Philips Surround Sound System that only has 1 HDMI port. I’d like to have my playstation hooked up to where I can hear it through my surround sound instead of on my tv’s speakers. Any suggestions?
