I recently set up a onkyo ht-r290 receiver I have it hooked up to a ps3, roku player and a VIP 722 box from dish. All are hooked up with hdmi going directly to the receiver and the hdmi out going to my Samsung ln40c530. Everything works fine except for when I watch tv. When watching tv it will only output sound to the front two speakers, but when I turn off the tv all of the speakers start working.as soon as the tv is turned back on the sound cuts out and comes in on the front speakers again. Not sure what I did wrong I turned off the tv speakers and I set up surround sound on the 722 box. Any help is appreciated.
