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.

Chet,

The fact that it worked fine with that friend's PC indicates some sort
of problem with your PCs.  I think you will find it to be a software or
computer configuration problem.
Figure out the differences between the setup on your PCs and your
friend's and you should have the answer.

Check the soundcard settings your computer has placed in the CODEC for
the K3 internal soundcard.  They should be in the 50 to 75% range.  You
should be able to use that and do the fine adjust with the K3 LINE IN
gain to achieve 4 bars solid with the 5th bar flashing on the ALC meter
- that is the proper setting for the audio.
