John,

That K3 internal soundcard should appear to the computer just like any 
other USB soundcard.  That can be computer dependent, so no specific 
advice can be given.

Select that soundcard in your data mode application and you should be 
"good to go" other than adjusting the soundcard levels.

Use DATA A rather than SSB because the K3 automatically turns off 
compression and sets the TX EQ flat.
Adjust the soundcard output audio level to drive the K3 ALC meter to 4 
bars solid with the 5th bar flashing, and you are ready to transmit.
Adjust the soundcard input level to suit a reasonable display on your 
application's waterfall.

73,
Don W3FPR
