Figured out the problem with ATIS voice. It's in SimGear with the
code for OpenAL/Alut 1.1, whereby with in sample_openal.cxx,
alutCreateBufferFromFile() does not give us the raw sound data, and
ATCVoice depends on it, which leaves the data and the data size
uninitialized.
The patch used alutLoadMemoryFromFile() instead, pretty much the new
version of the old deprecated alutLoadWAVFile().
Also someone might know a better, more portable way of converting an
ALfloat to an ALsizei. I'm simply casting it at the moment.
Thanks.
Pigeon.
