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.

My tv is supposed to accept surround sound through HDMI. I guess there is some sort of defect that's probably not worth fixing. It's $89 for the guy to come diagnosis it.

Yep, it makes no difference. I basically tried everything. The tv is pretty simple, actually. As much as I hate to, I may try the component option with splitters to share the signal with my Slingbox. I would only need 3 splitters since the Cisco DVR has two pairs of L/R audio jacks. I already have a good set of audio cables, so I would need to purchase 3 video cables and 3 splitters. Thanks for your help.

What can I use to split the component video signal that won't degrade the picture quality significantly? Where can I get them? Maybe I should just bite the bullit and switch my Slingbox to S-video and keep the tv picture quality as good as possible. Only problem here is I'm using my Slingbox S-video input for my Roku. All of this just because I don't want to manually switch back and forth between stereo and surround sound on my U-Verse DVR. I guess I could ditch the Roku feed since I can watch Netflix directly from their website and there is now a Netflix app for my Droid.

Thanks. $15 for 3 adapters is no problem. I'm really concerned that switching from HDMI to 1/2 a component video signal might be a significant degrade of the picture. I know moving my Slingbox from component to S-video would be a hugh degrade. I'll decide tomorrow if I feel like fooling with it and, if so, ride over to Radio Shack. As you say, I can alway return them. I think a high quality picture is probably more important than trying to eliminate the manual switching back and forth between stereo and surround sound.

I just decided to go ahead and try component video. I unplugged the component cables going to my Slingbox and plugged them into the tv. The colors are way more vivid and the picture seems much better. Also, as expected, I can leave the DVR set on surround sound with or without my receiver being on. I guess tomorrow I will go to Radio Shack and pick up some splitters for the three component video cables and hook my Slingbox back up. If that doesn't work, I'll try S-video to the Slingbox.

Well, I'm back to the HDMI cable and manually switching between stereo and surround sound. The component cables were great until I split the signal between my tv and Slingbox and the picture was unacceptable. I'm not willing to switch my Slingbox to S-video, so I guess I'll just stick with this for now.
