Ok, thanks. Thats good! Now follows my next question:
Where can I find compiled OpenAL windows binary which supports Ogg
Vorbis extension. I tried those on Creative site: OpenAL 1.1 and also
SDK version. They doesn't support. At least alGetString(AL_EXTENSIONS)
doesn't says anything about it, and two .dll files installed haven't ogg
or vorbis strings in them.
When I looked in source code in CVS, there isn't ogg suport at all in
win directory (but for example linux have), am I right?
