Sugar Live Build includes pulseaudio, which it says is needed to fix
speech synthesis, but that makes pulseaudio the first and default
mixer device. I didn't get as far as finding the ALSA runes to find
the correct mixer device. TOAST instead only presents one mixer
device, the hardware one, so I'm guessing it doesn't include PA though
speech synthesis does work.
