When using gnuradio with the default values  , the sound is
fragmented when played with pulseaudio .
Using the alsa device by name is acceptable, this not a best practice
Changing the nperiods from 4 to 25 solves the issue and gnuradio play
nicely with pulseaudio
default_input_device = default
default_output_device = default
period_time = 0.010
nperiods = 25 # 4 is too low for pulsaudio hook
verbose = false
I did not find any information about this issue or if this is related to
the value of min_nperiods, max_nperiods  with pulseaudio , those
values are not printed out .
is there a way to get a verbose output without recompiling from
thanks in advance
