Welcome to the Shack Garrett, Always go from the PS3 and other equipment connected to the receiver first. HDMI is the best connection method as it passes audio and video. if you want sound out of your display without having the receiver on you can then run an optical cable from the PS3 to the display as well.

Yes all you need is HDMI for both audio and video.

 

[tonyvdb]

Yes thats the best way to do it. The only issue is you will have to have the receiver on whenever you use the PS3 or any other device that runs to the receiver first and uses the display

Do you have audio out on the xbox set to bitstream?

 

[tonyvdb]

That will be in the Xbox setup menu.

Hmmm, well then Dolby 5.1 is the option you want (I assume that your already using that) it is possible that the games your using simply dont support 5.1 audio.

Ok, lets back up a bit. Are you hooking this up through a receiver before going into the soundbar?

I'm not really sure what else to suggest, Have you tried to contact Sony about this?
