I have same issues as you described. Think I will try that whine.wav file and see if that fixes it. Thanks.
Edit: Ahhh......That worked!!! Thanks again Falcon and Ted.
BTW, Do I still need to do this? Is this applicable?

"minimum_speed=15.00" or any speed setting you like. Also, I change to c4wind4.wav that was in the F3F sound folder.
Located in the F3F sound folder in the sound.cfg file.
