Running GNU Radio on Linux in VMware Workstation

GNU Radio
1

I have been working for a week or so on getting GNU Radio going on a
Debian
Linux platform running inside a VM.

GNU Radio is compiled and runs fine. The VM sees my Funcube Pro+ dongle.
Using ‘plughw:0,0’ got rid of the audio stuttering problem. After
struggling with a couple of the demo flowgraphs I downloaded and built
gqrx.

It runs. I can tune it to the local NOAA Weather Radio transmitter. I
use
that for testing because its very strong where I am. I have the same
problem there that I have in GNU Radio: no receive audio.

Can anyone give me some advice how to proceed? To answer the one
question,
yes, I am pursuing building a Debian system on a flash drive that I can
boot natively.

You can specify the audio output device globally for your system by
editing $prefix/etc/gnuradio/conf.d/gr-audio-alsa.conf (I’m assuming
that’s what you are working with given the use of plughw). You can set
that ‘plughw:0,0’ in as the ‘default_output_device’ argument. If you
are running PulseAudio, you can use ‘pulse’ for this, too, which tends
to work more reliably for me these days.
