FS2004 Wind Sound trouble - help?

I can not get the wind sound to play at the correct speeds in the default 737 or with the PMDG 737.The speed settings in the sound.cfg file don't seem to relate to the speeds at which the sound plays.In general, the sound starts playing MUCH earlier than the minimum speed, and the volume maximizes well before the maximum speed setting. In fact, the "ramp up" seems to be very sharp and unrealistic.Never had this problem with FS2002. I have tried re-installing FS2004, on 2 different machines, and the problem persists.Is this a general bug with FS2004? Could it be something to do with FSUIPC?Has anyone noticed this, and do you have a fix?
