Generic Module Severely Broken!

[Steve Holmes]

I just changed the AudioOutputMethod to 'libao' and now I get some
interesting results.  Swift-generic seems to be working fine but
espeak is totally dead with this configuration.  I set the debug level
to 5 in espeak.conf and as soon as I startup speech-dispatcher, I get
a bunch of errors in espeak.log.  I will insert that file below.
Again, I'm using the system-wide service and autospawn is turned off.
Also, it's complaining about unable to load libalsa.so; well, that
file is present and accounted for.
