When I ran a carwash forum, one time a guy sent me a mp3/wma of the sound, I posted it and within an hour the problem was solved. I don't think that a mp3/wma can be posted here directly, but if the OP wants to send it to me, I can post it on my site and it would be able to be listened to. I see you can post a video which would have the audio. Worth a try. My 14 seems somewhat load, but I really don't have a reference.
