Pulse Audio

I am running Jesse/Sid. I tried all of these things with no luck. I
even tried Janina's suggestion of disabling Pulseaudio (using her steps)
and that just resulted in Orca not speaking.
I thought I would try a little experimenting of my own, so I recompiled
espeak to use Pulseaudio. I then configured Pulseaudio to run as a
system service. When I attempted to restart espeakup, it said it
couldn't connect to PulseAudio: access denied.
On another note: I noticed, when booting, that speech starts before the
Pulseaudio daemon. Could this be causing a problem?
I'll keep hammering away at this. I agree with another poster that
someone should fix this bug.
Thanks,
Rob
