[R-390] Decoding with DReaM

[quartz55]

Can someone help me with DReaM?  When I feed the mixed IF (455 mixed down to 12KHz) into my SoundBlaster Audigy I hear the input monitor (line in) as well as the DReaM output (line out).  How do I turn off the input monitor?  Or is that a function of the soundcard?  It seems like I've done this before, but I can't remember, something about disabling the input monitor, but how?  If I turn down the recording line in, the output goes away too, of course.

Also, has anyone in the US had any luck decoding the DRM stations with Dream?
