I am not using that exact setup but will throw some ideas out that may help:
MMSSTV may have a filter (LPF or a BPF). Try it on and off.
Are you recording the audio as a wav file? If so, open it in Audacity or another audio player and play it from there into the virtual audio cable and into MMSSTV.
Try RX-SSTV instead.
I'm on Mac OS at the moment and I was just using Audacity -> Soundflower virtual audio cable > Multiscan 3B and I had artifacts on a good reception so I closed Multiscan 3B and Audacity and reopened them and the artifacts went away. So may be just try "turning it off and on again."

Is anyone out there successfully using an RTL-SDR with SDR#, a virtual cable, and MMSSTV to receive the pictures from ISS? If so, can you please share your settings with me or point me to a tutorial or something. I can see the signal coming in strong on SDR# and I can see that it's not static noise on MMSSTV, but it's not a coherent photo. I'm getting offset lines of color. For some reason, MMSSTV isn't getting the sync signals (that's a guess on my part). What am I missing?
