Orca does not speak on latest Ubuntu Live CD

Hi everyone,

Would it be best to download an earlier version of the Ubuntu Live CD to try
Orca while the latest one is being fixed?

I ask because it is not clear to me if Orca fails to work only in the Live
CD or also when this CD is installed to disk.  I just want to avoid
installing the most recent version if this will make it more difficult to
try out Orca.

Thanks,

Fernando
