Departed, no rush, it sure does sound confusing. First uninstall 2 remaining drivers, for Nvidia use control panel - programs, not just in the device manager. Maybe after you rebooted it installed those drivers again, they are in the cache now. Try to just disable the sound chip in the device manager. I tried your preset (without the drivers) in the virtual machine and it worked just fine. Now I wouldn't blame Realtek on this if it turns out to be just that driver. I think it could be that vLite forced the wrong driver to install. JohnnyFu, did you integrate any of the same drivers Marvell, Nvidia or Realtek?
