I had nothing called HD Audio bus controller under System Devices, although I did have 2 devices called High Definition Audio Controller. I uninstalled them both, then Scanned for Hardware Changes and got my old BSOD friend AtihdW73.sys. A reboot gave me another BSOD. Last Known Good Configuration got me up and running again, but with No Audio Output Device is installed, same as it's been all day.
