[op25-dev] No Audio

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
