[Elecraft] K3S - Win 10 Pro USB Audio Codec Issue

[N1VH]

Thanks to everyone for your suggestions, I tried them all.  After additional
sluething, I believe our K3S has an issue with the KIO3B board.  The USB
Audio CODEC will not load or be recognized on any computer (CAT control
works fine and is recognized in the Elecraft K3 utility).

Additional testing:  I tested other devices on our club PC.  It quickly
recognized the USB Audio CODEC for an IC7300 and mini external sound card. 
I then tried my personal K3S....and it quickly recognized both the USB VCP
and the Audio CODEC.   Next I attached the club K3S to my personal PC - same
result as with the club PC, it was not recognized on my computer either.  

I then tried reloading the firmware (again).  No change.  My conclusion is
that there is an issue with our club K3S.

I will have to call Elecraft support to see if there is a way to address the
USB audio CODEC or if the KIO3B must be replaced.
