RE: [op25-dev] OP25 GRC - Almost but not quite working

I still haven't checked out the latest code, but in my old code the default voice frame output was (null?). There are options for file output, null, external (hardware) decoder and internal decoder. You used to be able to spec this on the command line as an environment variable: export IMBE=soft I changed my default to be the internal decoder (see 'imbe_decoder_factory.cc').

Everything seems to working except I'm not getting any audio out of the OP25 block. I'm getting the "four line" output from the dibit output port when there is traffic on the channel, and the autotune output is outputting data. However, no audio. I put a scope on the audio output and it's a flat line at zero, even when the dibit output is "four lines". Any tips on how to further troubleshoot? Thanks, Andy
