BFO for SDR rx

I am using homebrew SDR receiver(YU1LM, DR2A) and I can see WSPR signal in the SDR waterfall . My problem is WSPR program does not decode any received signal, I can see signal receive in WSPR window as dark bands. I am using virtual cable to divert the decoded audio from SDR software to WSPR program.

Is it to do with BFO frequency?. What should be the BFO value for SDR?. Can WSPR program directly decode I/Q signals coming from SDR Rx.

Thanks in advance ,any help is very much appreciated.

happy to be a part of WSPR.
