[orca-list] pulseaudio doesn't work on desktop

[michael weaver <weavermicha googlemail com>]

i can get hardy to work with both speech and audio on my compaq 
laptop just as was suggested when i was told to select pulsesync 
in the gnome sound preferences.
however pulseaudio isn't recognised on my desktop which is an 
e-machine as it said that pulseaudio was not supported or it came 
up with some message about not supporting it when i selected 
pulsesync from the list of sound devices.
when i tried using alsa orca came up with some message about 
being unable to do sound mixing and to select a sound server or 
something like that because my sound card was tied up with using 
orca and espeak.
