Fwd: speechd-up debian install question

I agree with you 100%.  The sound card needs to be as rock solid as
the display.  Not only that, but:

- We're doing *extra* work to make our system's sound less stable
- Is allowing other people logged into my machine to play sound
*really* a security issue?  I mean... are they kidding?  Maybe the
mic, but a pure output device?

Honestly, I think what happed is it was easier to write certain parts
of Pulse Audio in user mode, and to save the author a little work, the
majority of blind Linux users suffer.

Now, the entire community of sound developers can go ahead and
continue claiming there's some hypothetical benefit to this mess, but
in my experience, you do work to fix stuff to make it better, not
worse.
