[Elecraft] KIO3BUPKT KIO3B Ugrade problems

[VE3CFK]

Purchased the upgrade about a year ago.  Acquired it to do digital modes and
do away with cabling, except for USB cable.
Worked great first time I plugged it in.  Worked with MMTTY and WSJTX-1.7.0
With N1MM (using USB) it would only display the operating frequency, but
function keys would not work.
With N1MM (using Serial) function keys would work but operating frequency
would not be displayed.
The problems with N1MM were duplicated on my PC (running Win7) and my laptop
(running XP).
The rig worked fine on a friends' PC (running Win7) using the USB link
between rig and PC.

Now K3 will not transmit using WSJX unless I crank the audio up very high
out of PC to the point of distortion.  And WSJTX now issues a warning that
there is something wrong with the Codec sound card.

The audio out of the K3 KIO3B works fine on WSJTX as it decodes signals. 
But audio out is the problem.

I could use some trouble shooting advice to confirm if KIO3B is working
properly or if my PCs are configured incorrectly.
