Re: [orca-list] Has anyone ever gotten Orca and Pulse Audio to work together well?

I've gotten them to work together without a delay, but that was with gnome-speech. Speech dispatcher seems to 
be rather unstable when espeak is used through Pulseaudio. I got rid of the delay by changing the resample 
method in daemon.conf. Ubuntu has its default set either to src-linear or ffmpeg, depending on the version of 
Ubuntu. Change this to the value:
This got rid of the delay and, incidentally, improved my resample speed and quality by a good margin. I 
haven't done much with Orca lately nor speech dispatcher, so perhaps the stability situation in sd with 
espeak has improved.

I'm trying to narrow down where the problem is that causes the 1/2

pulseaudio's main code trunk, or in Ubuntu's version of pulseaudio?

I have googled, but was unable to find a single instance where a blind
user was able to get Orca working well with Pulse Audio, without the
1/2 second delay.  I've also been able to convince myself that most of
the issues listed on

are not causing the problem.  In particular, I was able to run
pulseaudio with nice -11 and rtprio 9, and the delay is still there.
I haven't yet dealt with the out of date libcanberra.

Do any of you know of any case where pulseaudio has been configured to
deliver speech from Orca without the delay?  Is this simply a problem
now because Ubuntu was the version most blind users preferred before
Ubuntu switched to pulseaudio?  Has this problem been there forever?
