Help Me Understand The HDMI 5.1 DD Issue
I have a Cisco IPN-4320 DVR connected to my tv with HDMI. I have optical from the DVR to an Onkyo surround sound receiver. Normally, I watch tv with the surround sound system turned off. I get sound from the DVR to tv via HDMI. When I want surround sound, I turn on the Onkyo receiver and get sound from the DVR to Onkyo via optical. If I leave the Cisco DVR set on stereo, I get simulated surround sound, or I can change the DVR to surround sound and get 5.1. I would prefer to just leave the DVR set on surround sound, but if the Onkyo is turned off, I don't get any sound from the DVR to the tv via the connected HDMI cable. Why is that? This is the exact same setup I used with Charter cable and it worked. I did a search here and found threads where people are saying U-Verse now transmits 5.1 via HDMI. Is that not correct or is there something about the way I have my DVR wired that is preventing this? I'm confused on this issue. Thanks.
