Choppy sound with GNU Radio and PulseAudio
If you get choppy sound when using pulseaudio with GNU radio it might help to create a file ~/.gnuradio/config.conf (if it does not already exist) and add the following:
nperiods = 16
nperiods should be increased even more if the sound still remains choppy.
You could also set period_time to a value around 0.100 in the same file
