Hy,

Some time, I don't no why if I using Speech-dispatcher with Ubuntu 
11.10, after longer time usage random time the Espeak speech begin 
distorting, and only possible resolving this problem if I kill 
Speech-dispatcher and restart again.
I using Speech-dispatcher with native Pulse driver for Speech-dispatcher.
Speech-dispatcher packaged version is 0.7.1-6-ubuntu1.
Very difficult to reproduce this problem my notebook, this problem not 
depending what task  I doing when this problem is happening.
Normal sound playing is working fine always when this distortion is 
begin happening for speech output.

My notebook have following sound card:
00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio 
Controller (rev 03)

Anybody experienced similar issues if use Speech-dispatcher with Espeak 
module and confirming this issue?
I using both Speech-dispatcher and Pulseaudio with user mode.
My question:
In Oneiric release the Libao driver for Speech-dispatcher is supported 
without need remove Pulseaudio?
How can I possible setting this driver to I see this problem is 
resolving this driver change or not my system?
Unfortunately I forgot what packages are need this driver and what the 
proper configuration for Speech-dispatcher without I lost the speech output.
