Hella Matthew, There is a dedicated mailing list for Debian accessibility: https://lists.debian.org/debian-accessibility/
>From what you describe I would surmise that you do have sound after install but lack accessibility features like an audio screen reader. Sorry, I have never installed or set up a system for a blind person, so I do not know what is really important or difficult in this process. Here are three links that could of help: - Accessibility in the Debian wiki: https://wiki.debian.org/accessibility - the accessibility project on the Debian website: https://www.debian.org/devel/debian-accessibility/ - Orca screen reader wiki (part of the Gnome standard Debian Desktop Environment): https://help.gnome.org/users/gnome-help/stable/a11y-screen-reader.html.en
