         Dave,

         One of the things I have found here, is that my 850's don't like 
it when I have isolation transformers in place.  The audio is cut back too 
far for the LINE IN, and is still way too hot for the MIC IN.
         As suggested in another response, be sure that you have the LINE 
IN selected, not muted in the sound card software.  There may be enough 
bleed over from the MIC IN that you have some indication of audio in a 
waterfall display, but not enough to drive the demods..
