Re: pulseaudio

[Janina Sajka <janina@xxxxxxxxxxx>]

Will Walker may correct me if I'm wrong, but I don't believe Orca does
anything with pulse audio. Rather, I think pulseaudio is being
introduced by distributions. Specifically, I know for a fact that
Fedora/Red Hat has moved to it in Fedora 8. In fact it's a bit of a
problem as implemented in F-8, because it isn't launched until a gui
login, and there's no audio access before that. And, after the login,
there's still no root level access to audio--ever. I'm suggesting people
remove it for now on F-8 installations.
