Ok, here are the contents of my ~/.gnuradio/config.conf:verbose = true
[audio_alsa]
default_input_device = default
default_output_device = default
#period_time = 0.010 # in seconds (default)
period_time = 0.100 # in seconds
nperiods = 4 # total buffering = period_time * nperiods
#verbose = false
The actual change I made was to increase audio_alsa/period_time from 0.010 to 0.100. Play around with it until it works on your system. My only guess is that perhaps the default ALSA buffer sizes are small enough that they are often consumed by ALSA before GnuRadio will fill them.
