As creative labs and Windows 10 have decided that my
EMU 104 192Khz 24bits USB sound card was too old
I had to use the VB audio trick with my SDRplay USB SDR.
There is one point that was not mentioned before and that may be important:
Disabling any kind of AGC from the analogue software used to feed Dream.
SDRsharper in my case.
Strange behaviour can happen if you don't do that.
On the other hand setting the RF gain correctly can be tricky mainly
if you have only 8 bits resolution as with RTLSDR.
Results are almost as good as those from my old setup.
