Trouble hooking up xbox with HDMI

Hey there Parrot! I understand you're having some issues hooking up your console via HDMI through your receiver. Have you tried connecting the console directly to this TV, instead of a different one? Since it works with a different TV I would say the console is working fine. Are you trying to plug it into a port on the receive you know works with other devices? Maybe try plugging the console into the blu ray player port to see if it works. Let me know, thanks!

I have connected directly to this TV with HDMI. Video worked fine.  Not sure if audio worked because I don't have any speakers connected to the Pioneer TV (everything goes through Onkyo receiver).  I've tried plugging into the blu ray port - still no luck.  I tried hooking up my neighbor's xbox through the receiver.  It didn't work.  I actually have 2 of the same Onkyo receivers.  I tried through the other Onkyo receiver - no audio/video.

Is there any reason the xbox wouldn't work through the receiver, but I have no problems hooking up blu ray players, etc in the same manner?  I really need to run it through the receiver because I don't have speakers hooked up to this TV.  HDMI should pass video and audio from xbox to the receiver and then to the TV right?  Thanks for any help!!!
