Well, I still haven't "fixed" my loss of HDMI audio (when I turn off the receiver), but I do have a pretty reasonable workaround. HDMI audio comes back after a change of resolutions, it seems to "kick" the graphics card into realizing there is an audio capable device there again. So, as you can imagine, the workaround centers around that idea.
Anyway, here's the "fix" to make it easy to "pop" the resolutions and get the machine to realize that there's an HDMI audio device there again.
Go to this site and download the resolution changer application:http://www.softpedia.com/progDownloa...load_locations
Then, write a batch file that looks something like that:
D:\\SOUND\\DC -width=1920 -height=1080
D:\\SOUND\\DC -width=1792 -height=992 -apply
Change the "D:\\SOUND\\DC" to the path to the file you unzip from the above location.
Change the first line to a supported resolution by your TV, in my case, 1920X1080.
Change the last line to your preferred resolution (in my case, 1792X992, the custom resolution for my TV).
When you run this batch file it will flash the screen very quickly and restore the HDMI sound. Yes, it's still a PITA to have to do anything to get sound back, but this is MUCH better then going to the CCC and digging around to find the sound settings.
Hope this helps others. Also, again, is anyone else seeing the same/similar problem? It's only when I turn off the receiver; the HDMI audio device goes away and seems to not get re-detected. Also, does anyone know if a HDMI detective would fix this, or should I just wait for the next version of the driver/sound device (currently on RTK ver 2.0 of the HDMI driver)?
