Unfortunately, uninstalling the app "Parallels Access" does not do anything. The "Parallels Virtual Audio Adapter" is worst than a virus that messed up completely my Sound Devices and there seems to be no apparent way to remove it. Parallels 7 and 8 likely don't have this nightmare and it all starts with Parallels 9. You cannot remove this adaptor from Audio MIDI audio devices and Sound Devices in Preferences. I uninstalled Parallels 9 all together and even that did solve the problem as bits and pieces do not get removed.... waiting until Parallels designs software that could be uninstalled or creates a Parallels Uninstaller script that removes their "Parallels Virtual Audio Adapter". If sound is important to you think twice before installing Parallels 9
