Which audio problems you mean?

I tested it with ibmtts module under ubuntu gutsy but 
I am not very happy with it!.
Speech interuption is very slow (not usable) for me.
The alsa output is very fast and usable on my machine.
Perhaps someone can tell me whats the advantage of a soundserver for speechd?
It is only one more layer between the soundcard and 
speech-dispatcher.

Here is my cfg of 
pulseaudio. you can have a look and please tell me if I made something wrong!
I.ll then repeat my tests!

## Configuration file for the pulseaudio daemon. Default values are

# Extra verbositiy
; verbose = 0

## Daemonize after startup
; daemonize = 0

## Quit if startup fails
; fail = 1

## Renice the daemon to level -15 and try to get SCHED_FIFO
## scheduling. This a good idea if you hear annyoing noise in the
## playback. However, this is a certain security issue, since it works 
## when called SUID root only. root is dropped immediately after gaining
## the nice level and SCHED_FIFO scheduling on startup.
; high-priority = 0

## Disallow module loading after startup
; disallow-module-loading = 0

## Terminate the daemon after the last client quit and this time
## passed. Use a negative value to disable this feature.

## Unload autoloaded modules after being idle for this time 
; module-idle-time = 20

## Unload autoloaded sample cache entries after being idle for this time

## The path were to look for dynamic shared objects (DSOs aka
## plugins).  You may specify more than one path seperated by
## colons.

## The default script file to load. Specify an empty string for not
## loading a default script file. The

## The default log target. Use either "stderr", "syslog" or
## "auto". The latter is equivalent to "sylog" in case daemonize is
## true, otherwise to "stderr".
; log-target = auto

## The resampling algorithm to use. Use one of src-sinc-best-quality,
## src-sinc-medium-quality, src-sinc-fastest, src-zero-order-hold,
## src-linear, trivial. See the documentation of libsamplerate for an
## explanation for the different methods. The method 'trivial' is the
## only algorithm implemented without usage of floating point
## numbers. If you're tight on CPU consider using this. On the other
## hand it has the worst quality of all.
 resample-method = src-sinc-fastest

## Create a PID file in /tmp/pulseaudio-$USER/pid. Of this is enabled
## you may use commands like "pulseaudio --kill" or "pulseaudio
## --check". If you are planning to start more than one pulseaudio
## process per user, you better disable this option since it
## effectively disables multiple instances.

## Do not install the CPU load limit, even on platforms where it is
## supported. This option is useful when debugging/profiling 
## PulseAudio to disable disturbing SIGXCPU signals.
