Q: Windows 10 not recognizing iPhone 6s

Everything was working fine until about 2 weeks ago.  I like to download pictures directly from my iPhones to my Windows 10 computer.  Currently, iTunes will recognize the phone and work properly but the computer will not.  In the past I have heard to distinctive sounds when I plug in the phone.  Every time that I hear 2 distinctively separate sounds, everything works fine.  Starting 2 weeks ago I only hear 1 sound.  I have updated the Apple Mobile Device USB Driver in device manager.  I have also completely uninstalled iTunes and the associated programs in the proper order using the directions on the Apple Support page and then reinstalled.  I am at a loss... Can someone please help?
