Hi guys.  I set the sample rate at 1.024M because the RTL2832's minimum sample rate is 900k, the decimation at 32 and the samp_per_sym st 8 so I get a channel rate in the decoder of 38.4k.  I watch the the FFT Plot until the carrier freq pops up, I center that channel on zero, narrow the bandwith a little, looks like good 4FSK. So then I go to the Dibits tab, change the marker to dots and there is the four lines streaming across the scope perfectly, not one dot out of place.  But no audio.  What am I doing wrong?
Thanks,
Matt
