Hi, this is an edited version of the sound taking out some droan & click noises, also resetting waveform at beginning and end, see if this is better, the mixture setting for this sound is basically stock, only the priority has been lowered slightly & this wouldn't cause any sound anomilies.

I use this now but really didn't have the type of problem you have, if you are still having problems you may have to record it and upload for analysis.
