eSpeak uses an AUDIO makefile variable to configure what sound API to use:

   runtime -- pulseaudio with portaudio fallback
   pulse -- pulseaudio only
   portaudio -- portaudio only

It uses a fixed value of 'runtime' that you need to change by hand
(e.g. a sed rule or patch file).

It may also be that the default device does not provide sound output
(e.g. on my Raspberry Pi I have a USB soundcard on sysdefault). In
this case, the application using eSpeak needs to process the audio
itself instead of delegating to eSpeak as eSpeak does not support a
custom (non-default) audio device name.
