HDMI Audio & cable connection drawbacks

Well the edid emulator I picked up is a disaster, it was similar to the fueran, it is a Evanlak 4k device.

It just threw everything into chaos, reversed the TV & monitor identities, transplanted all of the monitor desktop to the tv, scrambled the desktop icons from the left side of the monitor to the right side of the tv screen, blocked any of the HDMI audio from the Radeon Graphics card to the receiver.........yikes

needless to say I have to send it back to Amazon with a description of what it has done. For whatever reason it and AMD Radeon don't like each other.....

Well, I have sorted out my issue.......

the route I took was not quite conventional, the need for having the TV being *seen* by the graphics card ALL the time just so that the audio to the AVR doesn't drop out was something I didn't realize was a prerequisite of the HDMI function.

So what I did was.........picked up a 2nd HD graphics card (fortunately for me I have a close friend who is an IT, he has quite a stockpile of older hardware from his various commercial/personal clients who upgrade their computers on a regular basis). He supplied me with a 6 yr old Geforce GTX card.
I now have 2 cards plugged into the motherboard, card 1 supplies the video to the 24" desktop monitor & card 2 supplies the video to BOTH the TV & the Receiver. I have two HDMI cables running from the pc .... 1 goes directly to the flatscreen, the other goes to the receiver, which in turns goes back to the TV to one of the 4 HDMI inputs.
So now there is never a loss of the voltage signal from the TV back to the video card which started this irritation. The cable to the receiver is the primary & sees all of the regular use where all of my video/movie/music is concerned. The cable going directly to the tv doesn't see normal use, it is just there to maintain the required voltage to keep the edid/voltage alive.
I can switch the tv HDMI inputs back & forth but the receiver input is the #1 of the two.

Not the most conventional, but it is direct, the problem is solved. No more HDMI audio loss to the receiver at all when I turn off the TV.

I appreciate the assistance that was given, had to think this thru to sort this out
