Something my Comp127 teach always told us in class. 'When you seem to hit a brick wall, take a step back, take a deep breath. Then go smash something destroyable. It's no use getting angry over something outside your control.'
As for the issue with no audio over HDMI, do you have the HDMI cable connected directly to an HDMI out on your video card? If not, then there won't be any audio. Where as DVI and HDMI are very similar if not the exact same in video spec, as far as I know almost no or no DVI connectors do. What is your specific Driver version, and your video card? I will see if I can dig into it deeper tomorrow.
Yeah, sadly that doesn't help. The problem is that when it automatically sets the resolution, it gets it wrong. ATI cards apparently have an option to turn this "feature" off, but looks like I'm stuck with it.
Another pain in my craw is that my SPDIF cable doesn't work. I've messed with it for hours and hours, but just can't get any audio over that HDMI cable no matter what I do. I had to compromise with the headphone out option.
I'm really stressed out over this. I have wasted I don't know how many hours researching and experimenting with this crap, and the whole reason I purchased this gear was to make my life easier!!!
Sometimes I think God really has it in for me.
I don't know if this will help or not, but I found this post specifically talking about 1080i, but it's regarding connecting to a TV. Hopefully this might help
It's NVIDIA. Here's the significant part from the NVIDIA control panel:
Driver Handling of Connected Displays on Desktop Computers (Windows Vista only)
When you connect a digital display to your computer while it is on - an action also known as hot-plugging - the driver detects the display and then configures the multi-display mode and display resolution based on the recent record of the displays connected. If no record exists, then the driver applies default settings. A popup message appears at the system notification tray alerting you of the change, giving you the opportunity to change the settings. This also applies if you disconnect, or hot-unplug, a display.
The automatic display configuration also occurs after you turn on your computer and boot into Windows Vista if the driver detects a change in display connections since the last Windows session.
It's Windows 7, but apparently this is the same. It considers disabling one of the cloned displays as "hot-plugging" apparently. Here's the error--the driver detection is wrong, assuming it's 1080p instead of 1080i.
It mentions a record existing...I wonder how I can save such a record.
Do you have an ATI or an NVidia video card? On ATI you can select an option to output in 1080i30NTSC or 1080i25PAL mode by checking a box. On an NVidia card it's possibly more difficult.
