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’).

Subject: [op25-dev] OP25 GRC - Almost but not quite working
I have the OP25 GRC demo that Balint provided up and running.
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
