Re: [orca-list] Orca, gnome-speech and pulseaudio

Hi Lorenzo
Check your /usr/bin/espeak-synthesis-driver, it should be a wrapper  
script envoking the driver through Pulseaudio if it's running. I'm not  
sure if the latest gnome-speech package bypasses pulse ornot, I use  
speech-dispatcher. If it's not, and it is the actual binary, move it  
to espeak-synthesis-driver.bin and create the following script:
#!/bin/bash
PATH="/bin:/sbin:/usr/bin:/usr/sbin"
if pidof pulseaudio >/dev/null && which padsp >/dev/null; then
  exec padsp $0.bin $@
else
  exec $0.bin $@
fi
Copy this to /usr/bin/espeak-synthesis-driver. This will wrap the  
driver in padsp, causing it to go through Pulseaudio again. This  
script will work with any other driver as well, just move the driver  
to its name with the extension .bin and symlink this script into place.
Alternatively, use speech dispatcher. This is what I'd actually  
recommend, especially with espeak, as their espeak driver is quite  
good and when used with pulse is much more stable than wrapping the  
gnome-speech driver via padsp. I wish gnome-speech had its own audio  
backends, this could take care of a lot of these stability problems  
with Pulseaudio.

   The major difference between a thing that might go wrong and a  
thing that cannot possibly go wrong is that when a thing that cannot  
possibly go wrong goes wrong it usually turns out to be impossible to  
get at or repair.
