pulseaudio; alsa-utils, pipewire plus pipewire-media-manager pipewire plus wireplumber sdl and enlightenment likely could all use an install feature that would locate each possible sound card on a system and try to make it speak or play tones if speaking isn't possible. Once that card is found, have the installer write a configuration such that when the sound controler is run that configuration gets used. I'm thinking along the lines of making all of these sound controlers easier to install for everybody, not just the accessibility user community.
