realtek audio driver for windows 7 64 bit

but it just will not recognise the gpu as a sound device no matter what I do I can see the Nvidia driver and it's set to default and the volume bar is there. so Im convinced it's a far deeper issue than just a realtek, windows setting sort of thing. All installed just fine and I can get full surround via it. Thought I would give Asus Essence STX ii a go to see what would happen. reinstalled drivers and it rebooted just fine.

Went into windows and went to sound, video and game controllers. So, went into bios and turned off HD Audio. I am beginning to think it would be easier to do a clean windows install now. I have updated drivers for the monitor, I have installed Asus sound managers but they say they cannot find an audio device, I have installed Intels latest chipset but all still the same. The mobo supports it and the drivers are up to date (and I have tried rolling back drivers as well). First, I need to find out what the issue is with getting sound from my monitor (and why it is seen as a telephone device) and secondly, what is stopping my system from being able to use more than 2 channels. But in setup, there is no option for anything other than stereo, no matter what version of realtek I download.

Then this happened and in an effort to restore some type of audio, i connected the mobo optical out (supports 8 channel audio) to the Onkyo receiver. When I removed it I resorted to running it through the monitor which has worked fine for years. I was running full surround through the soundcard to my Onkyo receiver to provide 5.1 surround audio. I shall give more info on setup: I removed my Asus Essence Stxii about 6 months ago as it was causing issues with a game. I did a safe mode clean of gpu drivers and then checked sound - nothing.
