Can I hook the Onkyo HT-S4100 to PS3 and HDTV without dvd player? - hdtv dvd player excellent first generation high definition dvd player

I had come with a digital optical cable to the receiver to the PS3 and the PS3 connected to HDTV via HDMI connection. So to the TV with surround sound I need to hear the perspective of the PS3 to the TV to change. Is this feasible or is an easier way? I do not use a DVD player, if you do not.
