Hi,

With latest openal-soft, Warzone 2100 starts, but there's no sound and
this warning is printed on the terminal:

        AL lib: pulseaudio.c:370: tlength (12780) is not a multiple of
        minreq (4096)!

MPlayer with -ao openal hangs on start. I'm attaching a backtrace. 

Any ideas? Perhaps this is a problem with PA rather than openal-soft?
