Certainly not factor of CD s.r. ... 44100, 88200, 132300... doesn't make much
sense to me :-))

Maybe some hardware cannot support 'strange' rates (and 10000 *is* strange). It
would be safer to use 8192, 11025, 22050 or 44100 Hz. Or maybe (probable) the
problem is not in hw but in windows OS code? They (Microsoft) *never* use
anything but 11,22,44kHz (see WAV docs). On the other hand, DirectX has support
for it... at least in 3d sound api.
