Yet more Realtek Driver Woes

HI.

i did a clean install of windows 10, and it is all good, until i tried some audio. it simply didn't work.

Looking further, on the device manager i had:

and in the system devices there was:

for some reason there are 2 x high definition audio controller.
I then tried to install the latest realtek driver. it went all through, but it did nothing. there were no files copied over or anything else.
I have tried various thing, but the end result it the same. things i have tried;
- i tried to install the latest version
- install a few other versions.
- even tried to install the version that came on the motherboard dvd.
- tried it install in safe mode
- deleted the hd audio controller and get windows to retry it again.
- manually copied the driver files to the install directory

is there any other ideas?

my system is: MB: gigabyte X79-UP4, CPU: I7-3620, GFX: GTX670.

I know the drivers work, as when i updated the machine from Windows 7, the audio was working, but since then i did a clean boot, and they dont install anymore.

also in the device manger, i go to the properties of the hd audio controller that has the issue, and in the events tab, the last line says device not started, and the information displayed is:
Device PCI\VEN_8086&DEV_1D20&SUBSYS_A0021458&REV_06\3&11583659&0&D8 had a problem starting.

Yikes.

I'm not optimistic, but as you have already expanded the drivers, have you tried manually updating the drivers from Device Manager?

You shouldn't have all that trouble with a fairly new system like that, particularly with a clean install. Surprising.

yeah i tried to update from the device manager, and every update option, it says that the correct driver is already installed.

yeah i know.. i think my next action is to reformat, and install windows 7, and get all the drivers installed on there, and then try to update again.
