My ps3 is hook on to my new vsx 44 receiver via hdmi n receiver to samsung 1080p tv via hdmi as well. I'm using two refrence 8" floor speakers. When I first turn on the ps3, there's sounds, but after I insert a game into the system, the screen went blank for a bit (like it had lost connection) n then back on, but then there's no sound, just pictures. Can anyone help please?
