A question about this. Given that there's no official way to disable
Pulseaudio in Ubuntu, why is it important that the espeak command-line
binary work without it? Ubuntu seems to be going full-speed ahead with
Pulse as the audio subsystem. I don't see any problem with that, but
with this being the case why worry about things working without
Pulseaudio? They sure haven't concerned themselves much about that in
other parts of the system, i.e. GNOME no longer has a non-pulse volume
control which means that you cannot adjust the volume without dropping
to the CLI if Pulse is not running. Wav file generation from the
command-line binary, if that's what you're worried about, will work with
or without Pulseaudio being loaded, and the current situation hardly
works when Pulseaudio *is* loaded which is most of the time.
Can you clarify this please?

Ultimately I think espeak should move to a platform specific solution, i.e use the best liraries for individual platforms, but thats a lot more work.
