do a proper clean install of the previous driver: download it from teh NVIDIA support page, boot into Safe Mode, run DDU , reboot, then install. A plain rollback in Device Manager sometimes leaves the problematic profiles in place.

hmmmm not sure about that sometimes the basic driver lacks features u need, like duplex options. try it, but keep teh full package handy. but hey ymmv

hmmm many GPU installers let you choose components in Custom install, and teh HDMI/DisplayPort audio driver is one of them... rerun teh AMD installer, chosoe Custom, and make suree the HD audio component is ticked. hope that helps :)
