Hello to all!
I have been trolling boards from here to hell and back trying to find a resolution to my HDMI Audio connection troubles. I will try to be as brief as humanly possible, but it's a long, drawn out story...
Our story begins sometime in the middle ages, whe... Ok, maybe not that drawn out. My basic setup looks like this:
LG 55LS7600 - 55" LED 3D Television, 240hz Refresh
YMH RX-V671 - Yamaha Receiver with various other things connected to it via HDMI (they aren't important to the story, so ONWARD!)
HTPC - Older AMD Phenom Processor running on a Gigabyte Motherboard, 8GB RAM, (Coincidentally has Realtek onboard audio that has been disabled in BIOS)
ARC is enabled on the TV and the Receiver, HDMI cable is plugged into the ARC HDMI socket (HDMI 1) on the TV itself. I don't really know what that means, but it was one of the many, many... oh so stinking many... threads that I have read.
The PC is connected to the receiver with a newly purchased HDMI Detective+ in between, via HDMI of course, by way of a Sapphire Radeon HD 6950, 2GB version. The receiver is connected to the TV by HDMI, and all is right with the world with the exception of the audio feed coming from the PC. Video makes it to the television just fine, but the audio drivers are giving me fits.
What I have done:
1.) After reading a million different forums, I went to Realtek's website and found the AMD High definition Audio Drivers, downloaded and installed them. Upon installation, I am prompted to reboot, which I do, and when windows 8 Pro, 64-bit, boots back up, I have no audio devices installed. Period. The only way to alleviate this is to repeatedly uninstall the Radeon HD VIDEO driver and then scan for new hardware. Eventually, an unknown audio device will pop up, and Windows will promptly install the best driver that Windows has, which doesn't work at all. Try installing the Realtek R2.70 software again, rinse and repeat.
2.) I have tried several older versions of Catalyst to see if the older audio drivers would work instead. They don't.
What I know:
1.) Inexplicably, the R2.70 drivers will install correctly without requiring a reboot and the sound works perfectly. So, I know that the R2.70 software package contains the driver that I need.
2.) I know that the audio drivers contained in the ATI Catalyst Control Center packages do NOT work. I get very digitized sound, if it works at all.
3.) I know that at various times, the R2.70 package will install an audio device labeled as "ATI HDMI Audio" or "AMD HDMI Audio", and neither of those are correct either.
4.) The correct driver from the R2.70 package installs as "Realtek HDMI Audio" (or something very close to that, in all cases here and above).
5.) As simple as it sounds to find the right driver, there are probably ~500 drivers in the R2.70 package, and most of them are called the exact same thing.
What I don't know:
1.) Why I lose the audio device upon reboot, even with the HDMI Detective in line behind the PC and before the receiver...
2.) Which friggin driver .inf file I need to pick to find the appropriate installation...
3.) Why Windows wants to install drivers that CLEARLY don't work with the hardware.
4.) Why hot dogs come in packs of 10, and hot dog buns come in packs of 8.
5. If it was the buns in 10's, and the hot dogs in 8's...
What it is NOT:
1.) It isn't the "Not plugged in" issue that so many people seem to have. There are absolutely no devices listed in the "Playback" tab of the sound panel.
2.) It isn't the hardware. I have actually had this setup running correctly a few times, though admittedly I stumbled into it like a blind squirrel finding an acorn. Once I changed HDMI inputs on the receiver or powered down the PC, it would not work correctly again until I screwed around with it for a few more days.
I hope that someone here has already dealt with these demons and can help me out. I am at that calm part of crazy now, where you decide that "there's more than one way to skin a cat" reasonably allows you to go the pet store and pick up some new knives on the way home... I kid, really...
Thanks for any and all help!
***Oh! One last thing... This is a long shot, but anyone who has a Radeon HD setup that is working, if you can just go into Control Panel -> Device Manager -> Sound, Video, and Game Controllers -> Right Click on "Realtek HDMI Audio" -> click "properties" -> "Driver" tab -> "Driver Details", and then list the driver file locations listed, I might be able to manually install from there.
