Hi there,
I need to play a sound as a prompt for blind users in
a Linux installer.
I ship the pcspkr module so I can just issue:
echo -e "\a"
So far, so good.
But I have been told that most modern legacy-free
PCs don't have pcspkr support anymore.
Corect. Few PCs do and virtually no laptops or other portable computers.
Then, what would be the bare minimum stuff to ship
in the installer to just play a sound, knowing that it
has absolutely no sound support at the moment (no
kernel module for sound, no userspace application)?
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.
Cheers,
S.M.
Thanks Sébastien. I will just hope that users will hear a beep,
and else tell them to wait a few seconds before typing the
command line then.
Cheers,
Didier
