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

Thank you! It worked for me as well. But I needed a value of 128 to get a continuous sound.
