This is pretty weird, when I disable all HD audio channels, they're all enabled again after I reboot the system. Sorry I totally missed the part with Clean Install and yes, I do always use Clean Install. It only happened twice as far as I know but since then I always check to make sure. Needless to say I was extremely miffed finding an extra User Account when I went into the Users Folder. I had certain drivers install that 'Updatus' User Folder despite having checked only the graphics and PhysX boxes after a Clean Install.

He didn't check the box for a 'Clean Install' as far as we know.

The clean install checkbox is at the lower left part of the check box driver listings and needs to be checked for it to work. He never stated that he did check the clean install checkbox so we have to presume as many don't. He already stated he used Custom/Advanced install and unchecks everything except Graphics and PhysX drivers so IDK unless it's just left over from not deleting the previous nVidia Folder.

They provide only the driver for the device function, no funky junk. In the future, when you get this sorted out, track down the audio driver from the chipset maker. a first install check for updates kind of thing.

It cleaned up a part (?) of the original install program (it was supposed to self-clean/delete) that was trying to endlessly install an update to the program. For the wife's case, it was a matter of rolling out CCleaner from Piriform. It was light years easier than trying to decipher what is and what is not a bit of driver and where these bits are located. Instance number one was easily resolved by using a program from Treexy called Driver Fusion, It does (or did at least) do an exhaustive search to uninstall all the bits and pieces left behind even during a what was supposed to be a clean install. + for clean install! I had a problem similar to this a couple years ago and more recently with a program my wife installed for her work (it auto-updates).
