And as I mentioned when I connect the pc directly to the HDTV using HDMI I get both audio and video.
2) I am using the most current drivers for my system. Do you know of one that would work with IDT that may be better than what is recommended?
3) I agree and just to be on the safe side I did try different, brand new cables.
4) I have not tried this as I do not have any other components. All of my entertainment comes directly from my pc. No cable box, satellite, blu ray, dvd; I am a true "cord cutter." This is all the more reason why I want to hook my pc up to the receiver using HDMI
I think you may have misunderstood some of what I was explaining.
The ARC just means the audio from the TV will be used instead of the audio from the input device. What I was suggesting was that you make sure the ARC is disabled. In fact, disabling every HDMI *option* (not HDMI itself, of course) is probably a good idea (including CEC) until this problem is solved.
The comment about the driver was that not only do you have to have the right driver but it must be enabled as the primary audio in many cases. To do so, go into your "Sounds and Audio" panel (under Control Panel) and make sure HDMI is still selected after you go from a TV connection to an AVR connection. When you are connected to the TV directly, look at this to see how it is configured and then compare against when connected to the AVR - they should be the same. If not, that is a spot to look at. Check device manager, too.
The comment about trying another HDMI component was not for a permanent configuration but more for a temporary test configuration. Can you borrow a small HDMI component from a friend? It really would make things easier.
Finally, as Joe said check to make sure you are set for Auto for the audio select on the AVR. You can tell the AVR to use analog audio for an input rather than HDMI, for instance. Auto should select the highest quality input that is attached and that would only affect the audio signal.
EDID is always transferred as part of the HDMI protocol. It tells the source component what the sink device is capable of handling. An EDID grabber would simply show you that part of the HDMI stream and (hopefully) translate from bits to English.
