Here is a wierd question. I have 2 HDMI's into my onkyo one is from my blue ray drive and the other is from my HTPC (home theatre pc). I have a weird phenominon that makes me wonder if i am just doing something wrong. What is the difference between the hdmi inputs for the receiver. I thought nothing. But my HTPC only works properly when connected to the DVD in. This same occurance happend with my 606. When i connect to any other port i loose sound, and i loose settings in the ati manager, ati's version of 19x10 is to large and need to scale it down to see everthing. My connection from the HTPC is pure HDMI, my video has an actual HDMI output and is able to run passthrough for even blueray just fine. When its connected to the dvd port. It may seem trivial but i simply swap the ports and both the blueray and htpc seem to work fine. However, ever the perfectionist i have trouble leave a htpc pluged into a port labeled DVD.

Any thoughts or eternal words of wisdom.

It seem in need to abridge this. The HTPC does not work properly on any of the ports on the 806. Which leads me to believe that the video card bound its self to the dvd port on my 606. So while that means i need to do some reinstalling to hopefully get this working again. It doesnt answer the underlying problem... What is different about the ports? what does the receiver report back to my box. My computer shows the tx-sr806, but how does it know what port??

Thanks!

Hey Cucore,

To be of any real help, I'd like to know what's in the guts of your HTPC. Are you using a Motherboard with integrated HDMI audio AND Video or are you using a separate video card with HDMI audio support? Some model numbers would be really helpful. I've been working on my own HTPC at home quite a bit lately and have had to tackle some issues over the last couple of months.

As for the Onkyo's HDMI inputs: The first thing you should check (provided you haven't already, of course) is that you have assigned your HDMI input ports to specific input selections. For instance: DVD will almost always have HDMI 1 assigned to it. I generally assign HDMI 2 to Video 1 and HDMI 3 to Video 2, but you can do it any way that you like. Once assigned, I might change the inputs name from "Video 1" to "HTPC" or "Xbox 360" etc.

To the best of my knowledge the 806 provides very little feedback information to the source device short of letting it know that it is active and turned on. I do not belive it is possible for your 806 to recognize anything specific about your HTPC rig. All you should need to do is ensure that you are sending it a video signal and a bitstream audio signal. If your HDMI audio driver doesn't support bitstream audio, then it should be converting everything to PCM.

It's been a couple of months since I really dug into the latest gear available for HTPC builders, but if memory serves having audio go out over the same HDMI cable as the video is a pretty new trick. Previously, it was necessary to have a separate digital audio output to get your audio. It's entirely possible you have some new gear- hence my question about the model numbers etc...

Looking forward to hearing back!

Good Evening, and thank you for your response.

I actually hade it set up quick happily. To be honest my biggest problem is i am dealing with vista, which is the most tempermental OS i have ever had to deal with in all my years. And ive been doing IT managment for a very long time. Anywho yah the audio goes out over the HDMI. Technically i also have a spidif cable but, if it tell the reciever to use it, it will ignore the hdmi cable and then i loose the video.  So the video card is a Radeon HD 3650 1GB 128-bit GDDR2 PCI Express 2.0 x16 HDCP. I havnt ever dealt with PCM or bitstream i just left it alone.

As for the input selectors on my Onkyo. I never did that. I figured the button on the front say DVD, Game/TV, DVR...etc It says the same thing on the inputs on the back. Why would i need to change them. I just press whichever  button i need. I did however rename them, which is handy.

From my understanding of Vista, which setting up a HTPC with a seperate touch screen in vista is a nightmare. Given the issues, i can only assume that my HTPC has bound it self to the ID of that port on my old 606. So all i can hope is reinstalling, and thus reassigning might resolve the issue. 

My underlying quesion is somehow my HTPC is able to tell the difference. Im wondering what the onko really reports back... hmmm

 All i know is when its not happy, the audio doesnt work and i the video is the wrong size... :?
