I can confirm that the hardware setup menu item is ALWAYS present when I have received the dialog to choose an audio driver when opening Cubase. For those who have checked the “Don’t ask me again” button and are no longer seeing this dialog box, try switching drivers, closing Cubase and re-opening it. This should restore the dialog box pop up. If not, try installing a different device driver alongside your preferred device. Just download one from Steinberg and install it. The first time you start Cubase, you should be prompted once more. Problem solved… Er, well, worked around.
