Thanks for the responces, guys. Spent my whole day trying to figure this out. The model of my pc is Acer Aspire X3400. In sounds and settings, I see NVIDIA hi def audio via HDMI. My pc uses windows 7 home premium. My tv is a 40" Sony Bravia xbr5. Denon 3808 reciever and Axiom 7.1 set up. I picked up the monoprice redmere HDMI's to simplify my set up and rid the clutter of bulky RCA's. I just grabbed the Oppo BDP 103 and I'm hoping not to need the comcast cable box anymore. I do have a toslink cable, but I was under the imression, sound would degrate using it. But what do I know.
If it makes a difference, I hooked up my Dell Inspiron 580S and also couldn't get any audio using an HDMI cable. It operates with windows 7 service pack 1. Thanks for any ideas.
