Corect. Few PCs do and virtually no laptops or other portable computers.

If you have no sound support then it seems unlikely that you will be able to play any sound. Your best bet would be to rely on the braille display to notify the user. I assume your user will have a connected braille display? If you have no sound support and braille isn't active at that point, you could always use a connected network to send a form of notification; that's the route I'd take if I were trying to hack some accessibility into a system for my own purposes and had to cope with such limitations.
