Hi!

I have done something similar with a home made DXD

If you have your DXD playing OK with WT and only microphone
connected to the DXD mic input AND using VOX you will 
be able to use WT with soundcard. Your DXD should respond
to Tx Focus from WT, i.e. when using the *-button. 

What you have to do is to connect your microphone to
soundcard mic input and the soundcard output to the 
mic input on the DXD. You might need a isolating audio
transformer between the soundcard and DXD to avoid 
a ground loop between computer and DXD. You have to adjust
levels in Windows Audio Volume set up in order to have
the same amplitude when you speak into mic and when the
DVK is playing.
