This was answered by others before but it has to do with copy protection and more. Let Onkyo explain it in more detail if my simple answer is not enough. There may be other hookups but let Onkyo tell you that.

I've got a sony BDP-350 blue ray player hooked up to my Sony-XBR TV using an HDMI cable. When I watch a movie I only get the sound in Pro logic. My receiver is an Onkyo with Dolby digital. I didn't have this problem with my old DVD player that was hooked up without using an HDMI cable. It looks to me like I've got the Blue Ray player set up correct for Dolby digital output. Any help would be greatly appreciated.
