0.8 is the first release with the audio plugin architecture.
When libao is loaded as a Speech Dispatcher audio plugin, libao's alsa
backend breaks.  This is an upstream bug in libao.  Other things that
load libao with dlopen, such as libao's Python language bindings, are
broken with libao's alsa backend as well.
See this bug report:
http://trac.xiph.org/ticket/1779
It's all well-documented there.

I could probably work up a patch to fix this for Linux, but I don't know
how to fix it for MacOS.
